There are edible variety of methods , can be dirty , Fried , soup , salad , pickles can also be pickled and production , as well as side dishes , embellishment and so on . Brussels sprouts cultivation techniques
Brussels sprouts , alias sprouts, cabbage child support , cruciferous cabbage Brassica species biennial herb , Brassica species axillary buds can form lobules ball variants. Leaflets ball with fresh edible parts is an important vegetable in Europe two centuries , North American countries in recent years become popular dishes on the Japanese market , which looks strange, the lovely , soft quality , fiber small and sweet, flavor, nutrition are better than cabbage . Mediterranean origin , previously only a small amount of cultivation in Taiwan Province . The late eighties , Beijing , Shanghai , Guangzhou and several other cities suburbs introduction, and gradually supply hotels, restaurants, Friendship Store and eleventh Asian Games athletes dine . After the mid-nineties , Shandong , Hebei , Henan , Jiangsu, Zhejiang, Guangdong , Guangxi and other provinces gradual introduction, in the outskirts of cities special vegetable base and small -scale cultivation demonstration area .

Brussels sprouts high in nutritional value of many types of vegetables , according to the determination of protein per 100 fresh vegetables 4.9 , the highest in cabbage leaf content , fat 0.4 , 8.3 carbohydrates , vitamins A883 international units of vitamin B10.14 cents, vitamin B20.16 cents, vitamin C100-150 cents, 42 cents calcium , phosphorus 80 cents, 1.5 cents iron . In recent years in hotels, restaurants, gift boxes holiday dishes, clean vegetables in supermarkets and other consumer groups are very popular. Currently still rare and special varieties of vegetables , but as people\'s living standards improve, people will gradually into the household table.
Brussels sprouts natured, sweet . It contains a special compound - iso- cyanate propionic acid such as fat . According to the latest research shows that within the ball leaves contain trace elements selenium , regular consumption of anti-cancer effect .
There are edible variety of methods , can be dirty , Fried , soup , salad , pickles can also be pickled and production , as well as side dishes , embellishment and so on . I. Characteristics and environmental conditions
( A ) Characteristics
Brussels sprouts grow erect stems , height divided into two types, high raw seed stem height 100 cm or more, and more sparsely ball shoots , leaves the ball big , mostly late-maturing , dwarf species of fast growth, stem height 50 cm or so, bud dense ball , small ball , suitable for early planting . Brussels sprouts and cabbage leaf similar , nearly oval , margin on the volume was spoon -shaped leaf surface different folds, petiole length , buds open , constantly sprouted new leaves , bottom-up around the stem leaf axils continue to give birth leaflets ball , commodities like tennis balls , 2-4 cm in diameter , compact and tight , is a miniature vegetables.
(Ii ) Environmental conditions
1. Temperature : Brussels sprouts like the cold , frost -resistant , not heat . In the autumn cold conditions , sunny during the day , at night there is a light frost , good quality. Its leaflets at high temperature ball perishable , will crack , the quality deteriorated. At high temperatures and strong sunshine , stunted growth , prone to pests and diseases . In the plant leaf growth requires temperatures higher, that is an average of around 20 °, is conducive to vegetative growth . Temperature was lowered to 5-6 °, the leaf growth inhibited. Cabbage of the requirements of a lower temperature , temperature for 10-13 °, leaves the ball in favor of the formation and nutrient accumulation , temperature higher than the above 23 °, is not conducive to the formation of leaf ball .
2. Light : Brussels sprouts is a long -day plants , but the light is not strictly required . When adequate light, vigorous plant growth , small and large solid buds , shoots the ball in the form of heat and light case , is not conducive to the formation of shoot the ball . Insufficient light and easy leggy plants , internode length , leaf ball smaller.
3. Water : hi moist soil conditions and indoor environmental conditions, but not too wet , so as not to affect the formation of root growth and shoot the ball .
4. Soil and Nutrition : Brussels sprouts suitable soil deep, fertile loose , rich in organic matter , water and fertilizer loam or sandy loam . More than the amount of fertilizer needed , they need nitrogen, phosphorus , potassium and trace elements combined application , each producing one thousand commodities for an available nitrogen 4.8 Qian, the 1.2 kb phosphorus , potassium 5.4 one thousand absorption ratio of 1 : 0.25 : 1.1 .

two. Production Technology

( A ) Crops Plan:
In North China , for example, there are several arrangements Crops
1. Spring light greenhouse : 12 Month - January nursery, planting in mid-February , after another harvest by the end of May ;
2. Chunlu ground : protected nursery in early February , late March open field planting, harvesting began in late June ;
3. Qiulu ground : the end of June nursery in late July - early August planting, in late October or solar greenhouse sheds were moved to heel , by the end of December harvest ;
The autumn light conservatory : early July - early August seeding, planting early September , January-February harvest.

(B ) sterile seedlings
Brussels sprouts seedling transplanting method to use more , so that both can save a lot of seed quantity , it can shorten the crop area in the field of time . Nursery should pay attention to choose suitable varieties , cultivating robust seedlings.
1. Variety selection should be based on climatic conditions in the region and the existing agricultural facilities and market needs , select suitable varieties . Based on years of practice , in Beijing in the spring planting should be selected 90 days after planting early maturing varieties can mature within, Japan\'s early support children , green olives .
2. Seed quantity brussels sprouts seeds about 4 thousand , mu seed quantity is 10-15 per acre planting 2000 .
3 . The plant sowing season , generally about 40 days seedling age , planting seedlings 5-6 true leaves . Seedling age will be extended in early spring when the temperature is low .
4 . The best way to use plug seedling nursery or seedling raising , precision seeding , a seedling . With a 72 hole disc spring , summer and autumn hole plate 128 is available . Matrix with 1 part peat vermiculite plus half copies, or peat , vermiculite , mushroom waste material 1 , covering all material with vermiculite , added 1.2 kilograms per cubic meter matrix of urea and 1.2 kg of potassium dihydrogen phosphate , fertilizers and matrix mix mix well after use. If the hole with 128 seedlings per acre required disk 16 , the amount of 0.9 m3 matrix ; seedling tray with 72 holes per acre need 28-29 months , 2.1 m3 matrix .
Before sowing the germination rate required to detect . Plug seedlings using precision seeding , seed germination rate should be greater than 90% , with hot water soaking after sowing seed soaking method (with the exception of seed coating ) . Put 1-2 seeds per hole , after covering vermiculite 1 cm . After completion of the seedling tray cover spray permeable to moisture from dripping out appropriate plug bottom outlet , the matrix maximum water holding capacity of more than 200%. Timely investigation seedlings after emergence to fill a vacancy .
5 . Seedling management
1 temperature: early spring seedling pay attention to insulation, controlled at a temperature of 20-25 ° , the latter leaked Qimiao attention . To prevent heat summer nursery .
2water, fertilizer : water holding capacity of seedling substrate is maintained at 60 % -65 %. 3 leaves a heart , combined with water 1-2 times Yemianpenfei .
If seedbed nursery , it generally takes twice as seedlings. Seedbed should choose a well-ventilated , facilitate drainage and irrigation of land per acre field with the kind of volume is 10-15 , acreage 10 m2 , shallow covering after sowing . Summer and autumn seeding, after seeding to use black shade net directly over the bed, and then irrigated to keep moist. Seeds begin promptly removed after emergence shade net , cooling rain . High temperature hot sunny day cover to expose evening , when 2-3 true leaves, seedlings , seed separation required once per acre seedbed 15-20 square meters.
(C ) colonization
1. Soil preparation , fertilization, mounding brussels sprouts long growing season , plant height , earlier planted plots cultivated , roots , sun mattress , arable land per acre application before maturity , finely divided organic fertilizer applied per acre 3000-4000 kg , nitrogen, phosphorus and K fertilizer 20 kg , after the organic fertilizer was applied in arable land , fertilizer in the furrow at the surface mounding open 5-10 cm, so Huanmiao timely absorb nutrients. Work after leveling Zuoqi , according to the form of the plot of soil , season, breed and other circumstances. Such as high altitude, convenient irrigation and drainage of sandy loam area , can be opened flat shallow trench or furrow cultivation ; if the soil is heavy clay , high water table , easy to water or rain areas , are advised to do Takakuro or running water level plot .
2. Planting early varieties do density 1.5 -meter-wide stretch of species double line spacing 50 cm , 1800-2000 planting plants per acre , late-maturing varieties of high seedling species per plot line 1 acre 1200 .
3 . Saplings plug or nutritive soilof seedlings, root injury with little or no root damage , up to 100% survival rate after planting . If you are using fertile seedbed seedlings before planting seedlings should be irrigated day , the next day to bring soil lump lifter, lifter after planting is finished today. Beijing area in spring open field cultivation , use sturdy seedlings , mulching after planting by drilling spacing , or after planting root pouring enough water , then erected a small shed with bamboo moisture , so it early Huanmiao plants grow fast in the summer It has formed a high temperature before lobular ball , the ball loose leaf reduction ratio .
Field management ( d) after planting
1. Scientific management of water and fertilizer after planting the seedlings watered often , in order to ensure the growth of the seedlings need to water . Especially in autumn cultivation, is the hot hot season , water management even more important. Irrigation can improve the field microclimate , can play a cooling effect, reduce the incidence of aphids and virus diseases . Mid-term plant growth , water management in order to see dry see wet principle. When the lower leaflets ball begins to form , but also regular irrigation to maintain adequate soil moisture . Timely rain to drain .
2. Row crop cultivators , weeding after each irrigation fertilization To Row crop cultivators , weeding and cultivating be combined with earth to prevent plant lodging .
3 . Science Dressing : dressing 3-4 times total growth period .
( 1 ) about 30 days after planting , fertilizing acre \\"a special card\\" activity 100-200 kg of organic fertilizer per acre , or nitrogen , phosphorus and potassium fertilizer three 20 kg , the depth of 5 cm or more.
( 2 ) shoot the ball enlargement period , per acre Point nitrogen, phosphorus and potassium fertilizer three 20K .
( 3 ) shoots the ball after the first harvest , then topdressing 1-2 times , specifically according to different varieties depending on the length of the harvest period , administered once per acre Taiwan \\"agricultural treasure like\\" organic liquid fertilizer 1 liter (N, P, K content were 9 %, 6 %, 9% ) with 100-300 times IRRIGATING , if the effect of better administration of drip irrigation equipment .
( 4 ) Yemianpenfei : height 50 cm around the beginning Yemianpenfei 3-4 times, each time by 0.2% 0.2% potassium dihydrogen phosphate, urea mixed spraying , or Bao Chan of Taiwan agricultural organic fertilizer 500 times spray.
4 . Brussels sprouts when pruning plants when stems form the central lobular ball , namely to the lower part of the old leaves , yellow leaves pluck , air and light in order to facilitate and promote the development of lobular ball , but also for future harvest lobular ball . Shoot the ball with the lower part of the gradual enlargement, the blade needs to shoot the ball next to take off from petioles , petiole will squeeze due to shoot the ball , so that the deformation becomes flat . At higher temperatures , the plants can not form the lower part of the axillary buds lobular ball , or the ball has become loose leaves should also be removed as soon as possible , so as not to consume nutrient or become aphids hiding place. At the same time you want to put off some buds depending on the circumstances , in order to reduce nutrient consumption , the lower the ball shoots grow full. Dwarf varieties generally do not need to pick buds . Abstract buds time to look at need. Beijing area Qiuzai brussels sprouts , beginning after 10 months late harvest , the temperature has decreased , before winter needs transplants protected heel , then it continues to grow , continue to harvest, may be topping in the open , in order to have more brussels sprouts leaves, but more leaflets ball , to increase production.
5 . Heel Beijing suburbs exposed to Qiuzai brussels sprouts , most varieties started harvesting the temperature will gradually fall , for the continuation of the harvest , to heel in greenhouses or greenhouse, it should be completed before the beginning of winter . To lump heel with soil , trenching, spacing of 30 cm × 50 cm, planting 4,000 acres . Greenhouse heel , winter use double plastic sheeting covered harvested from November to the end of February next year . Heel in the greenhouse will have to pay attention to leaked daytime temperature controlled at about 15 °, the night is about 5 °.
( E) protected cultivation techniques
1. Autumn autumn greenhouse cultivation in north China use greenhouse cultivation , not only to take advantage of the strong sunlight greenhouses , but also to prevent storm of attacks , there is no wind and the risk of waterlogging , and Qiumodongchu energy insulation, for the growth of brussels sprouts provide longer growing season , once cultivated successfully , superior open field cultivation conditions , the yield is higher. According to the characteristics of greenhouses , Brussels sprouts can be sowing until early June in advance , in order to prevent heat affect the growth of Brussels sprouts , should be safe in the greenhouse Ejecta facilitate cooling. With greenhouse cultivation attacks do not consider the wind and rain , it can be ditching planting, it may not be earth , picking buds work may be postponed until late October , so buds buds increases.
Greenhouse cultivation should pay attention to calcium supply , because Brussels sprouts need calcium bigger. When using microjet irrigation , often resulting in high soil salinity shed , spores cabbage affect the absorption of calcium. The solution is after the high temperature phase change Weipen to furrow irrigation should be large, and foliar spray of 0.3% of calcium phosphate , or 0.3 % to 0.5 % of calcium chloride , once a week , and even spray 3-4 times. Other management may refer to conduct open field cultivation .
2. Greenhouse cultivation Greenhouse in autumn and spring, Brussels sprouts can provide more suitable growing conditions , longer growing time , it will get better yields and quality products. Autumn sowing can be made in July to October . In addition to the choice of using a variety of early maturing varieties , but also cultivation medium-maturing varieties , picking buds of time depending on the circumstances and the cultivation conditions , to increase the number of dressing to prevent late Quefei . From November harvest close to the second in June . III. After harvest and postharvest handling
Harvesting standard : leaves the ball tight , dark , shiny , no pests . Cut with a knife or shoot the ball at the time of harvest , avoid breaking his hand down , so as not to damage the plants . In succession from the lower harvest early varieties . Late-maturing varieties can be harvested at the same time . To gently , into the perforated fresh bag , external carton , into cold storage at a temperature of about 0 °, shading, 95-100 % relative humidity conditions , can be stored for more than two months . Fourth, pest control
Common pests when planted black rot and Diaeretiella .
1. Black rot more in brussels sprouts growing late occurrence . More bacteria from the wound margin water hole , or on the blade invasion , the formation of \\"V\\" shaped or amorphous light brown necrotic spots, ill health at the junction is not obvious, lesions often have a yellow halo edge , the rapid development of outward yellowing of leaf tissue caused by surrounding dead . Bacteria enter the petioles or stems , petioles and stems make gray brown rot even necrosis , severe cases can spread to the sub- ball , causing wilting vegetables strains necrosis , severe necrosis child ball was brown dry rot .
Black rot is caused by a bacteria , germs come from plant debris in the soil , but also by seed transfer belt . Bacteria resistant to drying , can survive for two to three years , the growth temperature is 5 ~ 39 °, the optimum temperature 25 ~ 30 °. Brussels sprouts growing bacteria , mainly through watering , fertilizing , rain and strain has spread . Typically , hot and rainy , humid air , condensation or long blade pests serious wounds caused more conducive to pathogen infection . In addition, if the improper management of water and fertilizer , plant growth weak , pest control is not timely or stormy weather more severe disease .
Effective method for controlling black rot is:
1. Pursuant to black rot can harm a variety of cruciferous vegetables , it is best to take crop rotation with non- cruciferous vegetables .
2. Use disease-free seed or seed treatment agent , the choice of 47 percent of agricultural Jiarui WP 0.3% by seed weight ratio of seed dressing.
3. Brussels sprouts growing to strengthen field management , timely watering , fertilizing and pest control , reducing species wound. Timely removal of sick plants dish out outside the field properly. Dish the ball after harvest promptly clean the garden .
4. In the early stages, chemical control , the choice of 47 percent of agricultural Jiarui WP 600 times, or 77% killing WP 500 times , or 30% ammonia copper network agent 350 times, or new plant neomycin, streptomycin 5000 times spraying , 10 to 15 days prevention 1, according to the disease prevention and cure of 1 to 3 times.
(B ) there are two forms of aphids , when conditions are appropriate form wingless aphids produce winged aphids when conditions are not suitable . More damage young leaves and leaf vegetables strain , causing leaf curling and deformed leaves , poor growth vegetable plants , not the normal cabbage . Induce severe sooty , affect product quality.
Diaeretiella mostly light green, light yellow and green and yellow . A year can occur more than 10 generations in North China, South China up to 30 to 40 generations. Northern winter, generally do not form harm can occur sporadically on greenhouse vegetables. Open field vegetables often occurs there are two peaks in spring and autumn . Green peach aphid can harm occurred in the south anniversary . Persicae like yellow and orange , afraid silver . Color preferences can be used to prevent and treat it .
Control methods
1. In accordance with winged aphids afraid silver , may be in the laying of vegetable interval silver film or silver film strips hanging pull repelling aphids.
The winged aphids like yellow , can be set up in the field armyworm hang yellow sticky trap winged aphids, or about 20 cm from the ground planes yellow basin , soap or detergent 0.1% within the water trap and kill winged aphids.
3. Timely chemical control , since aphid generation cycle is short, fast breeding , spread rapidly , mostly gathered in the vegetable leaf or wrinkled dorsal shelter , spraying requires careful and thoughtful, inside protected areas or at room temperature using an aerosol mist spraying technology prevention better. Comfort spray can be used more than 20% concentration can be solvent 3000 to 4000 times, or 1% azadirachtin agent 800 to 1000 times , or 3 percent Mobi Lang EC 1000 to 2000 times spraying , the choice of 20 protected areas % off aphid aerosols, 0.4-0.5 kg per acre evenly placed , lit close shed 3 hours . start
