Drought-stricken wheat fields For wheat fields with severe drought, yellow spots and dead seedlings, water should be planted immediately after thawing in early spring, and 7-10 kg of urea per acre should be applied to promote early-onset seedlings. After returning to green, in the period of jointing and jointing, combined with watering, apply urea 10~15 kg per mu.
The three types of seedling wheat fields should have less than 450,000 total stems per acre before greening, and the three types of wheat fields with lighter leaf color and poor growth should be managed in time for fertilizer and water. Spring topdressing can be carried out twice. For the first time in the greening period, 5~8 kg of urea was applied per acre with watering; the second time was 10~15 kg of urea per acre during the jointing period.
The second type of seedling wheat field has a total stem number of between 45,000 and 600,000 per mu before returning to green, and the second group of wheat seedlings with a small population is 10 to 15 kg of urea per acre combined with watering. Wheat fields with insufficient wheat seedlings can be topdressed and watered in the early stage of the rise to the middle of the body; suitable wheat fields should be topdressed and watered in the late stage.
The first type of seedling wheat field has a total stem number of 60-800,000 per acre before returning to green. A suitable group of seedling wheat fields can be used for 12~15 kg of urea per acre combined with watering from the beginning to the jointing stage.
Wangmiao wheat field before the greening, the total number of stems per acre is more than 800,000, the color of the leaves is dark green, and the wheat field with strong trend should adopt the cultivating and suppression, reduce the application of nitrogen fertilizer, control the group length, prevent lodging and gluttony. Generally, 8~10 kg of urea can be applied per acre in the late stage of jointing.
Water-free wheat field in the dry land wheat field without water pouring conditions, it is necessary to suppress and combine the sputum, improve the drought resistance of the wheat itself. In the early spring, the soil is returned to the pulp or rain, and 5~7 kg of urea is applied with fertilizer or shovel. If the rain occurs in the middle and late stages of fertility, 5-10 kg of urea will be applied per mu.
