作物抗冻性的强弱与品质的特性、栽培措施等都有密切关系。秋播作物、强冬性品种应适时早播,利用秋高气爽、强光照晒等有利条件,培育健壮的幼苗,增强抗寒能力,促使其安全越冬。春性强的品种,则不宜播种太早,否则冬前营养生长过旺,抗寒准备不足,易造成死苗。此外,适宜的播种深度、垄作、施用有机肥、增施磷钾肥等,都可增加
The frost resistance of crops and the quality of the characteristics of cultivation methods are closely related. Autumn sowing crops, strong winter varieties should be timely sowing, the use of autumn and cool, bright sun and other favorable conditions, to cultivate robust seedlings, enhance the ability of cold to promote its safe wintering. Spring strong varieties, it is not suitable for sowing too early, or vegetative growth before winter too cold, lack of preparation for cold, easy to cause dead seedlings. In addition, the appropriate sowing depth, ridge farming, the application of organic fertilizer, increased phosphorus and potassium fertilizer, etc., can increase
