The sowing period of wheat is a key period for controlling various pests and diseases of wheat. In this period, it can save labor, save time and save medicine, and can control a variety of pests and diseases, with remarkable effects. The main control objects of pests and diseases in wheat sowing period are underground pests such as cockroaches, cockroaches, golden worms, wheat larvae, wheat sheath blight, total etch disease, viral disease, yellow dwarf disease, clump dwarf disease, smut disease and so on. Its control measures are: Select pest-resistant varieties to select pest-resistant varieties for the main pests and diseases in the local area, and do a good job of rational distribution of varieties. Create disease-preserving ecological environment, fine-tune the land, remove the diseased debris and weeds in the field. Adhere to the application of fermented farmyard manure and scientifically balance fertilization. Cultivation techniques such as athlete's foot, late sowing in the appropriate period, semi-precision sowing, etc. are used to cultivate wheat seedlings and improve the resistance and resistance of wheat itself. Treatment of soil in the underground pests, wheat worms re-emergence area, 50% phoxim or 40% methyl isoflavone emulsifiable concentrate 0.5-1 kg per acre, add 2-3 kg of water, mix fine sand 20-25 kg to make poison Spread the ground evenly in front of the soil plow and turn it into the soil with the plow. For the total eclipse re-emergence plot, use 50% carbendazim or 50% methyl thiophanate 2 to 2.5 kg per acre, mix 15-20 kg of fine soil, evenly spread the ground before plowing the ground, and turn the soil into the soil with the plow in. For the common pests of underground pests, 40% of methamidophos or 50% phoxim emulsifiable concentrate can be used, and 4 to 5 kg of water can be added, and 40 to 50 kg of wheat seeds can be mixed. Wheat sheath blight, smut, stripe rust, can use 0.1% to 0.15% of the seed weight of 2% ricketts, or 0.15% by weight of 20% triadimefon emulsifiable concentrate, or 12.5% ​​of ciprofloxacin Seed dressing at a dose of 0.12% by weight of the seed. Excessive use of triadimefon and hepatic fruit has an effect on wheat emergence and growth, and the dosage should be strictly controlled to avoid phytotoxicity. For wheat total eclipse, use 200 ml of 2.5% cola, add 1.5 to 2 kg of water, mix 50-100 kg of wheat, and dry it for sowing. Wheat yellow dwarf disease, bush dwarf disease, use 75% phorate emulsifiable concentrate 100 ~ 150 ml, add water 3 ~ 4 kg, mix 50 kg of wheat seeds, mix well and stack for 12 hours to sow. In the mixed areas of pests and diseases, it is necessary to vigorously promote the mixing of fungicides and insecticides, each metered amount, first mix the insecticides and mix the fungicides, and strictly follow the seed dressing operation rules to prevent poisoning of humans and animals. Seed coating seed coating agent is a new type of pesticide which is processed by compounding Insecticide, Fungicide, micro-fertilizer, plant growth regulator and film-forming agent. The seed coating has the advantages of simple, slow release and long-acting effect. In addition to controlling pests and diseases, it also has the function of seed fertilizer and should be widely promoted. Appropriately formulated seed coating agents can be selected according to the type of pests and diseases.

Chemical fertilizer is the abbreviation of chemical fertilizer, which refers to the fertilizer containing one or several nutrients required for the growth of crops made by chemical and (or) physical methods. It is mainly used to improve soil fertility and increase crop yield per unit area. The most common are nitrogen fertilizers, phosphate fertilizers, and potash fertilizers, which are chemical fertilizers that plants need more.
Pesticides refer to various sterilization, insecticide, weed control and other drugs used to promote and protect the healthy growth of crops.
Agricultural film is mainly used for mulching cultivation technology, which makes a huge contribution to increasing agricultural production and income and producing off-season crops.
