随着大毫,福丁等茶树新品种的不断推广,茶园绿盲蝽(Lygus lucorum)日趋严重,在江苏茶区已成为茶树主要害虫.因其初孵若虫体形较小,活动迅速,不易发现,一般茶场只能以为害症状来确定绿盲蝽的发生情况,延误了防治适期。为了及时有效地进行防治,笔者对第一代绿盲蝽发生期及发生量的预测预报方法进行了初步研究,并在实际预报中取得了良好的效果.发生期预测1.物候预测法根据4年的观察结果,早春绿盲蝽越冬卵的孵化进度与大毫、福丁、福云6号等品种的萌发同步,大毫品种出现一芽半展叶,福丁为一芽一叶,福云6号为一芽时(修
With the continuous popularization of new varieties such as Dazhao and Fuding, the tea plant Lygus lucorum has become more and more serious and has become the major pests of tea tree in the tea area of Jiangsu Province, which is not easy to find because of its small size and quick activity , The general tea plantation can only harm the symptoms to determine the occurrence of green bug, delayed prevention and control of the right period. In order to timely and effectively prevent and control, the author carried out a preliminary study on the prediction and prediction methods of the first generation Myzus persicae occurrence and occurrence, and achieved good results in the actual forecasting.Period prediction 1. Phenology prediction method according to 4 Year observation results, the early spring Ephemeroptera odoratum hatching progress and big mill, blessing, Fuyun 6 germination and other varieties simultaneously, the big species appear a bud half budding leaves, bingding a Bud a leaf, blessing Cloud 6 when a bud (repair
