| 摘 要： | 对1980-1989年河南棉区棉蚜种群动态分析表明,棉蚜为害可分为苗蚜和伏蚜两个时期,根据环境因子(气温、相对湿度、降雨量)和不同危害期,建立了2个模糊预报模型,并取得了较满意的预测效果。

| Abstract: | Population dynamics of cotton aphid in cotton fields of Henan Province in 1980-1989 are analyzed in this paper. The results show that the damage period of cotton aphid is at the seedling and flowering-bolting stages of cotton. With consideration of environmental factors (temperature, relative humidity and rainfall) and different damage stages, two fuzzy predicting models are established and good predicting result are obtained. |
