小麦从播种到成熟都受气象条件的制约,所以,了解小麦生长发育各阶段对气象条件的要求,提供栽培管理上参考是十分必要的.1973年由于对春麦品种选择不当,生育期变长,高温引起早枯后又遇雨季,造成很多地块绝收;1976年冬季低温,致使冬麦大量死苗,毁种面积占冬麦播种面积的2/3以上,损失很大.本文着重分析了朝阳地区发展小麦生产的一些不利的气象因素,积极地,实事求是地创
Wheat from sowing to maturity are subject to weather conditions, so understanding of the wheat growth and development stages of the meteorological conditions, provide a reference to the cultivation and management is very necessary .1973 due to the improper selection of spring wheat, growing longer, High temperature caused early dry and rainy season, resulting in a lot of plots forgiving; low temperature in winter 1976, resulting in a large number of winter wheat dead seedlings, destroyed species accounted for more than 2/3 of winter wheat sown area, a great loss.This article focuses on the analysis of the sun Regional development of wheat production of some of the adverse meteorological factors, and actively seeking truth from facts
