First, protect the roots and protect the leaves. Baogan is mainly to protect the leaves and prevent premature aging. During this period, with little rainfall, high temperatures, and large amounts of evaporation, dry hot air sometimes occurs. Therefore, it is necessary to scientifically apply fertilizer and water by focusing on extending the functional period of plants.
1, early pouring grouting water. After the wheat flowers are poured, the slurry should be poured in time. The wind should be selected with no wind or small wind, and no flooding should be used to prevent the strong winds from pouring.
2, foliar spray fertilizer. The phenomenon of defertilization in the late growth stage of wheat can be solved by foliar fertilizer application. General foliar spraying of 0.2% ~ 0.3% potassium dihydrogen phosphate solution, sprayed every 7 to 8 days, continuous spray 2-3 times, can be used alone, can also be combined with disease prevention and pest control to do a good "one spray three defenses."
II. Pest control and prevention of lodging
1. Do a good job of pest control. Diseases to be controlled during this period include powdery mildew, rust, and leaf blight; pests to be controlled include aphids and midge insects. Wheat disease prevention and control pests should be controlled early in the period and one spray should be used for prevention.
2, to prevent lodging. When wheat is watered late, be sure to watch the weather change. Wind does not pour, heavy rain does not pour, to prevent lodging.
