安徽省冬小麦春霜冻害气象指标的研究
Study on Meteorological Index of Spring Frost Damage to Winter Wheat in Anhui Province
摘要
Abstract
Based on the data of 12 agro-meteorological observation stations in Anhui Province,the variation of daily minimum temperature from 15 days before jointing stage to 20 days after jointing stage was ana-lyzed,aiming at different varieties of winter wheat (springiness and semi-winter).Taking daily minimum temperature as index,spring frost damage to winter wheat is divided into two grades:light and severe. The verification results show that,although the spring frost damage is affected by many factors such as landform,soil etc.,the index based on daily minimum temperature can basically reflect the regulation of the spring frost damage to different varieties of winter wheat,and can be used in the monitoring and warn-ing services.Then,the risk of frost was analyzed using this index,and the results show that,in the wheat producing regions of Anhui,light spring frost occurs frequently while severe spring frost hardly takes place .The high-incidence areas of spring frost damage to springiness wheat is obviously further south than that of semi-winter wheat.This conclusion can be used to guide the rational distribution of winter wheat varieties,and reduce the risk of spring frost injury.关键词
