近年来由于暖冬的影响,小麦生育进程普遍加快,造成年前拔节,遇冬春寒袭击后部分小麦主茎幼穗被冻死。不同品种冻害程度不同,苏麦6 号由于春性偏强,冻害偏重。其冻害程度与播种迟早、土壤质地、幼苗素质密切相关。适期晚播、半精量播种、提高麦苗素质、冬季镇压可预防或减轻冻害的发生。苏麦6 号受冻后恢复能力强,及时追施速效氮肥可使麦苗迅速恢复生长。
In recent years due to the influence of warm winter, the process of wheat growth generally accelerated, resulting in jointing years ago, after the winter and spring cold hit part of the main stem of young wheat was frozen to death. Different varieties of frost damage to different degrees, Sumai 6 due to strong spring, frost damage emphasis. The degree of frostbite sooner or later sowing, soil texture, seedling quality are closely related. Suitable late seeding, semi-precision sowing, improve wheat quality, winter suppression can prevent or reduce the occurrence of frost damage. Sumai 6 after the cold recovery ability, timely and timely topdressing nitrogen fertilizer can quickly restore the growth of wheat seedlings.
