Suitable for planting crops in May, how to plant crops in May, in May, the weather is still often unstable, the temperature is high and low, the vegetables grow weak, so how to plant crops in May? The following hot agricultural investment network for everyone I sorted out the crop farming arrangements in May and hoped to help everyone.
Crop farming arrangements in May
Wheat: Prevention of the occurrence of pests such as powdery mildew, rust, scab, midge, aphids, and arachnids.
Rice: First, do a good job in seedling management; second, timely drainage of the field; third, do a good job in the prevention and control of pests and diseases such as rice stem borer, early rice sheath blight, and field weeds.
Vegetables: Strengthen fertilizer and water management and harvest at the right time. Strengthen prevention and treatment of diseases and insect pests such as downy mildew and blight of fruits and vegetables.
Cotton: Fertilize the soil and transplant it at the right time. After the real leaves are unfolded, the seedbed is uncovered and the seedlings are sprayed to prevent pests and diseases, water spray, and the size of the seedlings are transplanted in stages, and the united water is poured. Check the seedlings and make up the seedlings, and control the tigers and mites.
Spring corn: timely replenishing seedlings, transplanting into a living, combined with cultivating and weeding to apply a top dressing, timely discharge and irrigation.
Spring soybeans: pay attention to the control of aphids and leaf-feeding pests, and follow the flowers and flowers to protect the pods.
Rapeseed: harvested in time.
Potato: cultivating alfalfa, filling horse water, spraying leaf fertilizer.
The temperature in this spring is lower than in previous years, and the growth of vegetables in protected areas is weak. The current management is rooted and strong. For warm crops such as tomato, eggplant, spicy (sweet) pepper and cowpea, it is necessary to control vegetative growth and enlarge Temperature difference between day and night, temperature management should be controlled at 24 °C ~ 28 °C during the day, the temperature should be increased at noon, or increase the cooling facilities on the shed, such as shade nets or thin old grasshoppers or muddy mud, otherwise noon shed The internal temperature can reach above 35 °C, causing baking or leaf snoring.
When the minimum temperature of the open field is above 12 °C, do not cover the grass at night, but in the afternoon, when the temperature in the shed falls to 22 °C~24 °C, the air outlet should be closed, keeping the temperature in the middle of the night slightly higher, which is conducive to the normal crop. Growing.
Diseases that are prone to occur in this period include downy mildew, powdery mildew, blight, and blight of melons; (late) blight of the solanaceous fruit, brown spot disease, and the like. Spray 5 times a broad-spectrum fungicide for 5 to 7 days, such as can kill, good Like, Baitai, Cuili, Shigao, etc., it is best to spray bacteria with agricultural streptomycin, new The combined application of phytomycin or neutrophin has better control effect.
For the abnormal growth of cucumber, like the phenomenon of catching the tip (the growth of cucumber to the growth point of the plant), it can be combined with the spraying growth regulator Yunda-120 or Bibao. When spraying pesticides, it can be mixed with foliar fertilizer, calcium galax, and gold carat to improve the control effect. The whitefly, aphid, and spotted fly that appear in the protected area should be sprayed with concentrated drugs, and sprayed with metoclopramide, avermectin, acetamiprid, and anthrax.
It can also be used for physical control by yellow plate trapping. The yellow plate coated with oil is hung in a place where the vegetable crop grows slightly higher, and has good trapping effect on the above pests. The yellow plate can be moved upwards with the growth of the plant, and the oil can be applied repeatedly after being contaminated with the insect. In the prevention and control, it is best to prevent and control at the same time as the surrounding greenhouse area, and eliminate these pests in the protected area to reduce the damage of the open crops.
Seeding and seedling: Chinese cabbage varieties planted in early May include Zhenbai No.1 and Xiayou No.3; radish varieties include Hanting; vegetables that need to be seedlings have wheat bran eggplant, and heat-resistant and disease-resistant varieties should be selected, such as the improved century king. Or Fulu long eggplant and so on.
