Children's cuisine is also called "Super Lettuce, Nanchong Cuisine (Yibin), Baby Cuisine and Baby Cuisine (Sichuan)", and its scientific name is "Baozi Mustard", which is a kind of mustard. On the thick roots, there are green buds wrapped around each other, just as countless children surround their mothers. One mother has many children, which is why it is called "children's food". Children's vegetables have the fragrance of mustard, but the taste is much better. They are sweet without bitterness, and when chewed in the mouth, the meat is crisp with little muscle and no residue. Beautiful colors, green leaves, white heart, sliced, green and white, if you use some red pepper to decorate when cooking, it is gratifying.

Planting techniques of children's vegetables

1.

1, seed selection: There are many local varieties of Ercai, and the disease resistance, commodity appearance, maturity, yield and quality of different varieties are different, with great differences. The early-maturing varieties include Zaozaowa and Zaowa No.1, and the mid-late-maturing varieties include Duofu No.1, which has the advantages of beautiful vegetable shape, high yield and good disease resistance. Early-maturing children's vegetables and middle-late-maturing children's vegetables have the same sowing date, but the length of growth period and the early and late harvest period are different.

2. Seedbed: The seedbed for children's vegetables should be in the shady area, and the soil layer should be deep, fertile, loose, convenient for irrigation and drainage, and loam or sandy loam without pests and diseases is the best. In the first and middle of August, the kang soil should be deeply turned over, and the lime15 ~ 25 kg per mu should be sprinkled for disinfection and the soil PH value should be adjusted (neutral and weak alkaline with pH value of 6.5 ~ 8), and only the lime should be sprinkled, so that the land will become hard and thin.

3. Sowing: In order to grow children's vegetables well, the choice of sowing date is very important and the key. Different sowing dates have completely different effects. If the sowing date is too early and the temperature is too high, it is easy to pull out the moss into a stick shape, blossom and form a tall foot. The sowing date is too late or too small, which is pineapple-shaped, not easy to grow into empty plants, easy to get sick, low yield, and lose quality and commodity.

2. Seedbed seedling raising of children's vegetables

1, sowing: The optimum temperature for seed germination of Ercai is about 20 ~ 28℃. Before sowing, the compartment surface is wetted with decomposed manure water, and the sowing is ensured to be even (sand can be mixed). After sparse sowing, cover with fine sand with a thickness of 0.5 cm, stone millet or plant ash, and cover it with straw or sunshade net after spraying pesticides. When 75% of the cotyledons of seedlings spread out horizontally, the straw or sunshade should be removed in time in the evening.

2. Intercropping: Intercropping the seedlings for 2-3 times during the whole seedling stage, and applying light human and animal manure for 2-3 times. When four true leaves appear in the seedlings, the seedling age is about 25 days, and the soil is removed from the seedbed for heel in at the row spacing of 10* 15 cm, and the roots are fixed by pouring thin human and animal manure, heel in15.

3. Strong seedlings: Seedlings sown before September 10 in the Gregorian calendar must be replanted by slow seeding and cultivating strong seedlings in heel in. Seedlings sown late for about 30 days can be directly replanted. Children's vegetables are suitable for old and strong seedlings, but not for young and tall seedlings. You can also use nutrition pots and trays for specialized seedling raising, and then plant them after the nutrition pots and trays form old and strong seedlings.

3. Field management of children's vegetables

1, Planting: Choose sandy loam or loam plot or greenhouse with deep soil layer, shelter from the wind and the sun, benefit water and facilitate irrigation and drainage for planting. In the south, you can choose paddy field after rice harvest, and use Kugaji for planting in winter to make efficient use of the land. After the rice is harvested, the main ditch should be dug and drained in time to open the trunk. Generally, the depth of the main ditch is 35-40 cm, the width of the ditch is 30-35 cm, and the width of the trunk should be controlled at about 3.5 meters. The harvested straw should be mechanically cut and grown to about 5 cm, and then spread on the field.

2. Land preparation: plow the field about 20 days before transplanting. Before plowing, spread 50-80 kilograms of compound fertilizer and organic fertilizer per mu as base fertilizer, and turn it over 30 cm. After the land is leveled, open the compartment according to the formula of 1.8 meters. Before planting, open holes on 10, with 3 rows in each compartment. After mixing the soil with decomposed compost, cover the litter with calcium superphosphate, and cover the soil.

3. Transplanting: after 10, choose to transplant with soil in sunny days or sunny days, water the roots in time after planting, and after planting survives, apply fertilizer for people and animals1~ 2 times to facilitate seedling raising. 35 ~ 40 days after planting in beginning of winter, the fertilizer was applied again, with 2500 ~ 3000 kg of human and animal manure per mu, 20 ~ 30 kg of urea, 20 kg of calcium superphosphate, potassium sulfate 15 kg and a small amount of phosphate fertilizer, boron fertilizer or compound fertilizer. A small hole was opened at a distance of 15 cm from the plant, and the fertilizer was applied and covered. About 60 days after planting, the children's vegetables are in the early stage of rapid expansion, and the biogas slurry of human and animal manure and urea are applied once.

Prevention and control of diseases and insect pests of children's vegetables

1, after the seedbed is sown and covered with manure, spray 500-800 times of 40% dimethoate, aphid and chlorpyrifos, Aketail, imidacloprid and other pesticides on the surface and its vicinity to kill aphids and ants (to prevent the removal of children's vegetable seeds) and other related pests.

2. To prevent and control damping-off of children's vegetables at seedling stage, seeds can be soaked with 300-500 times solution of hymexazol, Quyi Dan and Miaojundi, and the seedbed soil can be mixed with 20 grams of fine soil10 ~15 kg to spread the bottom and surround the roots, or sprayed with 600-800 times solution.

3. In the early stage of soft rot, 300 times of 14% cupric chloride solution, 2000 times of 72% streptomycin sulfate (500 mg/kg), or 3% bio-antibiotic wettable powder 1000 times of solution can be sprayed.

4. At the initial stage of viral diseases, 300 times of 5% Zhi Bing Ling, 400 times of 5% bacterial toxin wettable powder, or 500-800 times of Banba can be sprayed. If virus-infected plants are found, they should be uprooted, packed in plastic bags and destroyed outside the field.

5. The downy mildew is sprayed on the back of leaves with 500-800 times of Frost Blight and Frost, or 500-700 times of 58% Lei Domil or 70% Paterson, once every 5-7 days and for 2-3 times in succession. The temperature is slightly higher, hot and cold, rainy and humid, etc. are prone to downy mildew.

6. Spraying 50 ~ 80% dichlorvos EC 8 ~1000 times, 50% phoxim EC 1500 times and 40% pyrethroid EC 2,000 times to prevent and control flea beetle.

7, ground maggots with 50% isocarbophos 600 ~ 800 times the liquid one tablespoon irrigation.

8. Aphids can be sprayed with imidacloprid, mixed with toxic insecticide 1000 times or lured and killed with yellow board once every 7 ~10 days. When the disease is serious, it will lead to the failure of children and vegetables or the appearance of baldness, which will seriously affect the yield and benefit.

Note: Never apply urea dry during the whole growth period of children's vegetables. Fertilization should follow the principle of light before heavy, control before chasing. Excessive use of nitrogen fertilizer should be controlled to prevent plants from growing in vain and growing too vigorously and tender, which will lead to delayed hair growth, small hair growth and little frost resistance, which will seriously affect the yield and the quality of commercial vegetables. In autumn drought and early winter drought, light manure should be frequently applied to protect seedlings, and there is redness at the top in the late stage of lack of fertilizer and water, boron fertilizer and untimely harvest during the growing period. Children's vegetables should not be deeply ploughed to remove seedlings, which may damage the roots and cause diseases. They should be shoveled 2 ~ 3 cm above the soil surface or pulled out by hand. It is not suitable to continue cropping related mustard for more than 2 years in the cultivation area of children's vegetables, otherwise the yield will be low and the disease will easily occur.
