摘要
针对江苏沿海地区转B t基因抗虫棉田棉盲蝽发生量加大、发生期提前和绿盲蝽比例明显上升等新情况,研究制定出了"两个改进、两个加强和一个建立"的B t棉田棉盲蝽预测预报新方法,即改进调查方法、改进短期预报方法,加强对成虫的预测、加强对重点发生阶段的预测,建立棉盲蝽预测预报数据库。
According to the new situations including great occurring number of cotton plant bugs, early occurrence date and rising occurrence rate of green plant bugs in transgenic Bt cotton fields in coastal area of Jiangsu province in recent years, the improvement forecasting method was set up, which contained two improvements, two strengthening and one building, namely improving investigation methods, improving short - time forecasting methods, strengthening the forecasting of adult bugs, strengthening the forecasting of key occurrence stages and building forecasting database of cotton plant bugs.
