First, organize technical forces and in-depth field guidance. Agricultural departments at all levels should regard grasping the field management in the spring as a major event, carefully organize technical forces, and go deep into the grassroots to guide production. It is necessary to conduct a survey on current spring crop production conditions, master the dynamics of seedling development, and adopt classified guidance. As seedlings and indigenous land provide specific management measures, they effectively help farmers do a good job in field management in the spring.
Second, clean drainage, prevent waterlogging. Waterlogging is a major obstacle to the high yield of spring crops in our province. All localities must firmly establish the idea of ​​preventing waterlogging early, and take advantage of the favorable conditions of the recent sunny weather to mobilize the masses. Before the Spring Festival, clean up the “three channels†and extra-territory channels in the fields and reduce the water table. At the same time, in combination with the Qing Ditch, earthworm mud soil in the roots of the crops, pressure grass insulation protection seedlings.
Third, cultivating loose soil, scientific fertilization. For soil compaction, seedlings, and weak seedlings, we must pay close attention to cultivating loose soil, increase soil permeability, apply a small amount of fast-acting chemical nitrogen fertilizer, and promote improved seedlings. For individual overgrowth plots, deep cultivating or repression of wheat seedlings can be used, while nitrogen fertilizer can be controlled to prevent leggy and enhance the ability of plants to resist cold. Before and after the Spring Festival, when the canola was applied at a height of 5cm, the fertilizer was applied in a timely manner. Generally, 10kg of urea was applied between the rows per acre to promote spring growth.
Fourth, make up herbicides, prevent pests and diseases. For those fields that have not applied chemical herbicides or are not suitable for Tianzao in the early stage, we must quickly apply supplements such as isoproturon and gaizoong according to the type of weeds to kill weeds and prevent weeds from growing in the spring. occur. According to the forecast of major crop pest occurrence trends in the province, this year, wheat head blight is a moderate occurrence, and rape sclerotia is a moderate occurrence. All localities shall strengthen the monitoring and forecasting of pests and diseases of spring crops, prepare adequate pesticides, and guide farmers to prevent and control them in due course.
Fifth, strengthen the management of vegetable fields. Before the onset of the cold wave, open-field vegetables were covered with non-woven fabrics, old agricultural films, straw, and shade nets to keep warm at night. Greenhouse vegetables should be fastened at night with a large greenhouse film to keep warm and prevent freezing. When the temperature rises on sunny days, ventilation and ventilation should be conducted in time to control the temperature and humidity in the shed. Appropriately control the growth of vegetables such as cabbage and lettuce to prevent premature bolting. Do a good job of preventing and treating diseases such as vegetable root rot, downy mildew and powdery mildew.
