摘要
通过对自然光3年的逐日观测表明,一定照度的光时受天气状况影响发生明显变化,晴天光时长、阴雨天光时短,低温伴随着短光时。武汉地区光照度(E)大于501x,光时大于13h45min的持续时间是6月~8月1日,该时段内基本可满足光敏核不育的光照条件。
Three-year daily field observations show that the number of hours of usual light in-tensity varies, depending on the sky state for the research area,with the increased(decreased)number on a clear(rainy)day aidlow temperattire in connection with short period of insolation.For the study region,the period of light intensity E> 50lx and the number of insolation > 13haiid 45 min spai1s June to August 1,a condition that meets the needs of light for the photoperiod-sensitive genic male sterile rice.
