从1976年以来,我县曾经有3年出现过小麦死苗,受害面积大,受灾重,不论是早麦还是晚麦,不论是冬性还是弱冬性品种,均发生不同程度的死苗现象。为了摸清小麦死苗的原因,我们进行了多年调查研究,认为小麦死苗主要是由低温、干旱造成的,而土壤水分的含量直接影响着小麦的安全越冬。 Since 1976, there have been three dead smuggling of wheat in our county in the past three years. The area affected by the disease is so big that it is severely affected. Whether it is early or late wheat, both winter and weak winter varieties experience varying degrees of dead seedling . In order to find out the reason why dead wheat seedlings, we conducted years of investigation and study, that dead wheat seedlings mainly caused by low temperature and drought, and soil moisture content directly affects the safety of winter wheat.
