摘　　要：2004年~2006年在石河子大学农学院黄萎病圃对新疆棉花黄萎病的发生与气象因子的关系进行了研究,3年的试验结果显示,新疆棉花黄萎病的发生与内地明显不同,每年只有1次发病高峰;应用DPS统计软件对各气象因子与黄萎病发生的关系进行相关性分析,显示该病的发生与温度、湿度和降雨有密切的关系;在石河子棉区,若7月10日以后温度适宜(24~26℃)、雨量大、雨日多、相对湿度较高时,则黄萎病发生较重,否则发生较轻。We have studied the relationship of cotton Verticillium wilt and meteorological factors in disease garden of Agriculture College of Shihezi University from 2004 to 2006.The results of three years demonstrated that cotton Verticillium wilt only has one peak in the whole growth period in Xinjiang,which is obviously different from the result of other provinces.The DPS analysis indicates that the occurrence of cotton Verticillium wilt has close relation with the climate condition,such as temperature,relative mo...
