1. Drought-resistant and flood-proof wheat in the late growth period, with high temperature and large evapotranspiration. Watering flowering and grouting water at the right time has the best effect on increasing yield. The wheat yellow water can also regulate the field microclimate and prevent or reduce the damage of dry hot wind . Irrigation frequency and water volume should be adapted to local and seedling conditions, so as to maintain the field's maximum water holding capacity of 70-80%. At the same time, as the grain weight increases, the center of gravity of the plant rises, and attention should be paid to rapid irrigation and drainage; to prevent lodging. 2. After foliar spraying and heading and flowering, the plants have already been closed. For wheat fields that lack fertilizer, foliar sprays are used, which can not only be directly absorbed and utilized, but the efficiency can reach more than 90%. The type and concentration of fertilizer are 0.2% potassium dihydrogen phosphate, 5% plant ash, 1-2% urea, ammonium sulfate, superphosphate, etc., and the liquid volume per mu is about 50 kg. Generally, it is sprayed once at the beginning of grouting. The second time, the first time is at the booting stage. 3. For head blight, 50% carbendazim wettable powder or 50% thiophanate powder diluted 1000 times can be used to prevent and control, and as a conventional measure, spray it continuously from the beginning of flowering. For rust disease, 8-9 grams of active ingredients of Fenmeining can be used per acre and sprayed with 50-100 kg of water. Both thiophanate and Fenmeining can cure powdery mildew, while Jinggangmycin is better for sheath blight. For aphids, use 6-8 grams of 50% Dimethoate wettable powder (3 to 4 grams per mu) with water 30-60 kg, or 40% dimethoate 1000-1500 times solution, 40% dimethoate 1500～ 2000 times liquid control, and can also cure planthoppers, leafhoppers and so on.
