小麦越冬死苗是造成小麦减产的重要原因之一。死苗的原因是由温度为主导,再加其它各因素综合作用造成的。温度是人们难以控制的,而如何通过栽培措施防止或减轻越冬死苗,就成了当前小麦栽培上急待解决的问题。我们通过对乔屯乡1983年小麦死苗现象的调查与分析,认为与栽培措施的关系,有以下四个方面:一、与整地质量及冬前镇压的关系。整 Winter wheat seedlings overwintering is one of the important causes of wheat yield reduction. Dead seedling is due to temperature-led, combined with other factors caused by the combined effect. The temperature is hard to control by people, and how to prevent or reduce winter dead seedlings through cultivation measures has become an urgent problem in the current wheat cultivation. Through the investigation and analysis of the phenomenon of dead wheat in wheat in Qiaotun Township in 1983, we think the relationship with cultivation measures has the following four aspects: First, the relationship with the quality of soil preparation and the suppression before winter. whole
