小麦冻害一定程度上影响着小麦的产量,预防措施得当能有效地防治冻害的发生,减少冻害的危害,进而提高小麦的产量。1小麦冻害发生的原因1.1施肥不合理合理施肥是小麦获得丰产的基础。但个别农户仍有重施化肥,轻施农家肥,或者不施农家肥;重施氮肥,忽视磷钾肥和微量元素肥料的合理搭配的倾向。导致小麦不能正常发育,无法形成壮苗,一旦春季出现较强冷空气侵袭,就很容易发生
To some extent, the frost damage of wheat affects the yield of wheat. Proper measures of prevention can effectively prevent the frost damage and reduce the harm of frost damage, thus increasing the yield of wheat. 1 wheat frost injury causes 1.1 unreasonable fertilization reasonable fertilization is the basis for wheat to obtain high yield. However, some peasant households still have the tendency of reusing chemical fertilizers, applying peasant manure lightly, or not applying peasant manure; reusing nitrogen fertilizer and ignoring the rational collocation of phosphorus, potassium and trace element fertilizers.
