5. Prepare a small prescription for seedbed soil
Mix the field soil without vegetables with well-rotted organic fertilizer at 6:4, and add 100 grams of 68% refined nail cream manganese zinc water dispersible granules and 100 ml 2 per cubic meter of seedbed soil in proportion5. When it is suitable for fun, and after the seeds are sown and covered with soil, spray the surface of the seedbed with 400 times of 68 fine nail cream and manganese-zinc water dispersible granules, which can effectively avoid the occurrence of diseases such as vegetable seedling withering, anthrax and cataplexy.
6. Preparation of small prescriptions for acupoint disc nutrient matrix
The substrate was prepared according to the ratio of peat:vermiculite 2 l, and ternary compound fertilizer 1-1 was added per cubic meter of matrix5 kg (the ratio of nitrogen, phosphorus and potassium of ternary compound fertilizer is 15 15 15, if it is a winter and spring birth control seedling, 2 kg needs to be added), and 100 grams of 68 fine nail cream manganese zinc dispersible granules and 100 ml of 25% fludioxonil suspension seed coating agent was used for soil pesticide sterilization treatment.
7. Small prescription for fermentation treatment of farmhouse fertilizer
After mixing the unrotted chicken, cattle, pig and other farm manure with EM bacteria and crop straw, you can also add 5 kg of ammonium carbonate fertilizer (gas fertilizer often said by farmers), which has a high temperature and fast fermentation. (per 2 3 cubic meters of farm manure + 500 kg of crushed straw + 3 kg of em bacteria), cover with waste plastic film and seal it tightly, and it can be completely fermented in 10 15 days.
8. Small prescription for soil improvement in new sheds
After mixing 6 8 cubic meters of farmhouse fertilizer and 5 kg of EM bacteria per mu and evenly applying it to the shed, the soil is deeply cultivated to enhance soil permeability and activity, and it can be planted and produced after 7 10 days.
9. Small prescription for sterilization in high-temperature stuffy sheds
(1) Clean shed:After the harvest of the last crop in June and July, the crop residue is removed, the weeds in the field are removed, and the weeds are transported out of the shed to be buried or burned.
(2) Laying straw:Corn stalks, wheat straw, rice straw and other crop straw are cut into 3cm 5cm inch segments by means of equipment, and after corn cob and waste mushroom material are crushed, they are evenly spread in the shed according to the amount of 1000 kg and 3000 kg of mu.
(3) Paving organic fertilizer:3000 kg of 5000 kg of rotten organic fertilizer such as chicken manure, pig manure, cow manure, etc., evenly spread on the straw or fully mixed with crop straw and spread. At the same time, 30kg of ternary compound fertilizer (effective content of nitrogen, phosphorus and potassium is 15:15:15) or 15kg of diammonium phosphate are mixed. The specific dosage can be determined according to soil fertility, crop type and planting mode.
(4) Sprinkle fast preservatives:Apply fast-preserving agents such as rot enzymes, mix 2 kg per mu, and turn 25cm 40cm deep, and prepare the land to make a flat furrow conducive to irrigation.
(5) Irrigation:Irrigate the soil in the shed until it is fully moistened, and the relative humidity reaches about 85 (there is no open water on the surface, and the soil can be held by hand to not disperse).
(6) Double layer coverage:Cover the floor with mulch or a whole piece of plastic film to seal the individual joints. At the same time, close the shed and check the shed film, repair the hole hole, and keep it clean and good light transmittance.
(7) Stuffy shed time:After the closed shed, keep the high temperature and humidity in the shed for 25-30 days, of which there are at least 15 days of sunny and hot weather. During the period of high temperature stuffiness, rainwater should be prevented from entering the shed. The suffocation can last until 5 to 10 days before the next crop is planted.
(8) Planting preparation unwrapping and drying shed:Open the vents, remove the mulch covering, and carry out the drying shed. After the surface is suitable for dryness and wetness, the land can be prepared for the cultivation of the next crop.
10. Small prescription for seedlings and seedlings
After the vegetable seedlings have grown into true leaves, they can be treated with robust and disease-proof biological bacteria. The seedlings were sprayed with 500 times of raw polyglutamic acid or 200 times of Bacillus subtilis wettable powder to promote the growth of seedlings and enhance the stress resistance of seedlings.
11. Small prescription for seedling prevention and control of virus transmission

The second is to use 35% thiamethoxam suspension 2000 3000 times liquid to spray and irrigate the roots of seedlings, which can effectively prevent and control whitefly pests and aphids, and prevent the spread of virus diseases and other diseases, and the efficacy lasts for more than 30 days.
12. Small prescription for the prevention and control of seedling stem base rot
Before seedling planting, 500 times of 68% refined nail cream and manganese zinc water-dispersible granules or 6500 times of 25% dioxonil was sprayed on the soil surface of the planting hole, and then the seedlings were planted, which could effectively prevent and control stem base rot.
