First, timely control of pests and diseases
Due to more rain in the recent period, the occurrence of wheat powdery mildew in high-yield areas is more serious, which will aggravate the occurrence of wheat scab, and aphids are also migrating to the wheat ears. It is now a critical period for prevention and control. All localities must seize the opportunity to choose appropriate chemicals, such as choosing 12.5% ​​diniconazole spray to control powdery mildew, carbendazim to control head blight, and 10% imidacloprid or 3% acetamiprid to control aphids. Wait.
Second, do a good job of spraying fertilizer outside the roots
During the period of wheat grain formation and filling, spraying fertilizer outside the roots is very important to strengthen wheat roots and protect leaves, promote wheat filling, delay senescence, and increase grain weight. It can be used for foliar spraying with 200 grams of potassium dihydrogen phosphate + 500 grams of urea per acre for 5-10 days after oxidation, and 50 kilograms of water for foliar spraying. The wheat can resist the damage of dry and hot wind.
Third, control watering in the later stage of grouting
15 days after the wheat blooms, watering should be properly controlled. One is to prevent the head of the wheat from falling down in the wind, and the other is to prevent the leaching of nitrogen, which affects the gloss of the grain, the keratin rate and the processing quality. The third is to irrigate the wheat with yellow water, which will cause the suffocation of the wheat root system, accelerate the death of aging, and reduce the grain weight.
