Key Technical Points for Protecting Crops from Cold and Keeping Them Warm in Winter

As the cold winter arrives, for farmers, besides keeping themselves warm and protected from the cold, they must also protect their crops from cold and freezing damage to prevent the adverse effects of low temperatures and frost. Agricultural experts offer a few tips:

For different crops and different growth stages, field fertilizer and water management should be strengthened to promote crop growth and improve cold resistance.

For open-field crops, ditches should be cleared in time for drainage; lowering the groundwater level can effectively prevent freezing damage. At the same time, in conjunction with clearing the ditches, mud should be earthed up around the crop roots, which suppresses weeds, preserves warmth and protects the seedlings.

For greenhouse facilities, measures such as covering with straw curtains, non-woven fabric, shade nets or multi-layer coverings can be adopted for insulation, while ventilation and air exchange should be carried out at the proper time; spraying Hushu Dajiangjun can maintain the plants' own temperature and prevent and control the occurrence of diseases. For vegetable seedbeds and seedling-raising plots, spraying Xin Gao Zhi Mo to form a polymer film, together with covering with small-arch greenhouse film or straw and other coverings, can provide insulation.
