Under the influence of drought, the growth of wheat was characterized by sparse population, dwarf plants, fewer tillers, yellowing of lower leaves, and early earing of booting. Since March, wheat in most regions has entered the heading stage. During this period, wheat is in a period of sensitive water demand. Drought severely affects normal wheat production.

Actively seek water sources, timely irrigation and irrigation. Irrigation should not be carried out at noon. Wet irrigation techniques should be adopted. A small number of times should be used to prevent flooding. For wheat fields that are lightly affected, straw, straw, leaves, etc. should be used to cover the soil between wheat rows to reduce evaporation loss of soil moisture.

Spraying crop drought protection agent (Fulvic acid preparation) to reduce the degree of stomatal opening and inhibit water transpiration loss. Or destroy the old leaves, yellow leaves, and diseased leaves of the wheat base to reduce the consumption of water and nutrients and ensure the effective growth of the plants.

Spray foliar as appropriate. Urea can be used per acre 2 to 3 kg, watered 100 kg; or with 0.3% potassium dihydrogen phosphate solution, that is, 150 grams per acre of potassium dihydrogen phosphate water 50 kg, etc., foliar spray, can play Fertilizer water, improve the effect of drought resistance.

If strip rust, powdery mildew, and locust infestation occur at the same time, triadimefon and anticonvulsive agents can be mixed and sprayed to prevent infection.

After the drought has weakened and the ability to resist coldness has declined, we must pay close attention to the changes in the weather. Before the arrival of the cold current, we should adopt measures such as universal watering and spraying of antifreeze to prevent frost damage. Once cold injury occurs, timely remedial measures such as watering and fertilization should be taken to prompt the wheat seedlings to resume growth as soon as possible.
