摘要
本文研究了春大豆果荚期以黄毛鼠为优势种的鼠害防治指标,建立了春大豆果荚期鼠害的动态防治指标模型(X_s=341.14×(CF)/(EYP)+8.4034),提出了春大豆果荚期在不同经济系数(F)和不同产量水平下各种不同的防治指标。
The economic threshold for the rodents as pests of which Rattus losea Swinhoe was the domi- nant during the early soybean pod periods had been studied in this paper.By investigating,the mordel (X, =341.14×(CF)/(EYP)+8.4034) of dynamic ET during early soybean pod periods was provided under different economic coefficients (F) and yield level (Y).
