摘要
选择 196个要素 ,建立数据库 ,利用关联度、图解法结合典型年份的生物学指标进行初选 ,使用了 5大类 10种以上的方法 ,计算出 60 0余个模型 ,从中选出棉铃虫第 2代、第 3代的发生期、发生量的中、短期预报模型。
Since the beginning of 90’s, the harm of cotton bollworm has been very serious and attracted people’s attention In this paper, 196 synthetic factors were selected for establiment of database By using the degree of correlation and graphic method selecting factors according to the value of typical year’s biological index, and using the method over ten types, over 600 models were calculated From these models, the medium and short term forecast models for cotton bollworm of generation Ⅱ and Ⅲ were selected
