General repression and deterrence, top of the earth.耙耱 Or repression can crush the soil, bury the soil, lift the soil, call up deep water, and promote root oysters. Through repression, the formation of capillaries in the soil, the deep soil moisture rises along the capillaries to the upper layer of soil, which is conducive to nourishing the growth of the root system. The favorable time for early spring ploughing and licking is the linging period, which starts when the top layer is 2 cm deep. In the early spring, the ploughing should be shallow, and the rake should be light to prevent injury to the roots and the cold. After the wheat has risen, it can only be plucked, and it can be properly deepened to facilitate the roots to tie down.
Early spring fertilizer. After returning the soil to the soil or rainfall in early spring, fertilize the fertilizer or open up the ditch to apply nitrogen fertilizer, and apply 5-6 kg of urea per acre. Phosphate fertilizer without applying fertilizer to the base fertilizer must be supplemented with diammonium phosphate in the nitrogenous fertilizer. Where there is biogas, biogas residue biogas slurry or filthy manure can be sprayed.
Foliar fertilization. Due to prolonged drought, the soil moisture is seriously deficient, affecting the emergence of wheat seedlings, and FA-dry land dragons and Nonghaha drought-retention and water retention agents can be used for foliar spraying to improve the drought resistance of wheat seedlings.
Pay attention to pest control and weed control. Dryland wheat is mainly controlled by aphids, spider mites, rust, and sheath blight. The control of weeds can be completely controlled before the jointing of the wheat and temperatures above 5°C.
Protecting the seedlings with membranes to prevent bruising in livestock and poultry in spring. Plastic film coverage is the main technical measure to increase wheat production in the region. In the spring, the wind is so thick that the mulching film does not cover the water. It is found that the mulching of the mulching film must be compacted in time, and the spring of livestock and poultry will seriously affect the photosynthetic area and dry matter accumulation of wheat, resulting in reduced production.
Create conditions to supplement irrigation. Spring rain is as expensive as oil. If the drought persists, it will cause incalculable losses to wheat production. Therefore, in areas where the water sources are not far away, the use of “Little White Dragon†to implement dryland wheat supplement irrigation can greatly reduce the drought.
