通过对冬小麦死苗情况进行抽样调查,造成冬小麦死苗的原因主要是由于品种不对路,自身抗性差,地下有害生物危害,栽培管理不规范等。根据不同的死苗原因,采取引进抗旱抗寒品种,适时播种,提高播种质量,精细的耕作栽培管理等,培育壮苗,使植株制造和储存较多的有机营养,增强体内糖的含量,提高抗寒抗旱能力,运用综合的农业技术措施,防止有害生物侵袭,减轻冬小麦死苗。 Through the sampling survey of the dead seedlings of winter wheat, the causes of dead seedlings of winter wheat are mainly due to the different varieties, poor self-resistance, harmfulness to underground pests, non-standard cultivation and management. According to different causes of dead seedlings, it adopts the methods of introducing drought-resistant and cold-tolerant varieties, sowing them in time, improving sowing quality, fine farming and cultivation management, cultivating strong seedlings, making plants produce and store more organic nutrients, enhancing the content of body sugar, Cold drought capability, the use of integrated agricultural technology and measures to prevent the invasion of pests and reduce winter wheat seedlings.
