玉米秃尖的气象条件分析

AN ANALYSIS OF METEOROLOGICAL CONDITIONS CAUSING BARE TIP OF MAIZE EARS

摘要:

本文通过对影响玉米秃尖长度的气象条件进行分析,找出了影响吉林省中部地区玉米秃尖的主要时期和主要气象因子:抽雄至8月上旬子粒发育期的降水;建立了各主要时期降水与玉米秃尖长短的定量模式。同时,确定了玉米秃尖与温度、降水、湿度匹配指标。

Abstract:

By analysing the meteorological conditions the major period and principle meteorological factors which cause bare tip of maize ears were found in central area of Jilin province. These are : heading stage to first ten—day of August （grain developing stage） and precipitation in this period. The equations of precipitation on length of bare tip of maize ears were set up. Meantime,a relative index of the length of bare tip with temperature,precipitation and moisture was determined.
