This year, the area of ​​sown wheat is relatively large, and the seedlings are generally weak, and some wheat fields are biased. At present, it is the key period for strengthening the spring wheat in the wheat field, promoting the transformation of the seedlings, and setting up a high-yield shelf. 1. Crack down, increase temperature and keep warm. Repression can sink and loosen loose soil, improve soil moisture, and facilitate the absorption of nutrients by roots; planing can increase ground temperature and reduce evaporation of soil moisture. After the pressure is applied, it has the effect of lifting, protecting, and resisting drought. 2. Promote control and integration, classification management. (1) Poorly plucked wheat fields should be watered early to protect against drought and seedlings. In wheat fields with serious losses, the average temperature on that day was stable above 3°C, and water was poured at noon. The individual wheat fields combine about 10 kilograms of urea with watering Mushi, and appropriate amount of diammonium phosphate. (2) In wheat fields with good lye, the management of fertilizer and water should be based on seedlings. (3) For "a needle" wheat seedlings, early scratching and early fertilizer should be performed. In the early spring, when the top layer of soil was frozen and 2 centimeters in depth, scratching was started, and nitrogen and phosphorus fertilizers were topdressed in time to increase the number of clams and panicles. As long as the sensation is acceptable, avoid watering in early spring so as not to reduce the temperature and affect the soil permeability. When the average temperature is stable above 5°C, combined with watering Mushi 8 to 10 kg urea. In the jointing stage, 5-8 kg urea was applied to promote the development of spike flower and increase the number of grains per spike. (4) The good wheat seedlings in the growing season are treated with fertilizer and water, and combined with watering mu, it recovers 10-15 kilograms of urea. 3. Prevention and control of pests, scientific weeding. After the average daily temperature exceeds 6°C, select sunny days from 10am to 4pm, according to field weeds, scientifically spray pesticides. 4. Prevent diseases. In the spring, the weather is changeable and it is necessary to attach great importance to the prevention of cold damage to wheat in early spring. Immediately after freezing, topdressing urea, spraying plant growth regulators, foliar fertilizers, and promoting seedlings quickly restore growth and development.
