摘要
根据霜冻害的观测和调查资料,进行气候学研究,阐述了我国冬小麦发生霜冻害的生长发育时段、最低气温范围、地区分布规律和年际变化趋势,讨论了防御霜冻害中值得注意的几个问题.
Based on the data of frost damage observation and survey, a climatological study was engaged. The region distribution, tendency of interannual variation, harm period and minimum air temperature were expounded. Finaly, some problems of defence were also discussed in frost damage.
