First, topdressing and watering   For the coming year, the wheat seedlings will return to green and improve the tillering rate to create a good soil, laying the foundation for the spring tube. The amount of winter fertilizer accounts for about 20 % of the amount of topdressing . The plots that do not apply bottom phosphate should be combined with nitrogen and phosphorus. The wheat field that has been applied to the bottom fertilizer is not chased by winter fertilizer. Watering the winter water should be carried out at a daily average temperature of 7 to 8 °C. Evening wheat fields should not be poured into winter water.  Second, deep, crackdown, loose soil Above average fertility irrigated wheat fields, the beginning of winter, the total number of tillers per acre to achieve spike plan 1. When the time is 5 times, the roots should be cut deep, and the roots should be leveled to prevent the pressure and the wind from failing, and the winter water should be poured in time. If the overgrown population is overgrown, it can be used to suppress tiller growth before wintering. In the wheat fields with extensive tillage and sloping, the soil is crushed before the ground is frozen, crushed and smashed, compensated for cracks, and kept warm. Pressing wheat should be carried out after noon, so as to avoid frost damage in the morning, and salt and alkali should not be suppressed.  Third, the freeze damage defense In the wintering period, the application of farmyard manure cover wheat and the suppression of strong seedlings can be used for heat preservation, fertilizer field and antifreeze. Wheat leaves are frozen, as long as the tiller is not frozen, the quick-acting fertilizer should be applied early to promote seedling transformation; in case of dry freezing, it should be combined with watering and drought resistance.    Metal Circular Saw Machine,Angle Iron Cutting Machine,Servo Feeding Machine,Plasma Cutting Machine Shaoxing Sunfong Intelligent Equipment Inc. , https://www.zjsxsunfong.com
