本文测定了吉林省公主岭市玉米地中20 m×20 m矩形TBS(R-TBS)及长60 m和30 m的线形TBS(L-TBS)的控鼠效果、保护辐射半径及其防控害鼠的经济效益。在此基础上评估了玉米产量与L-TBS捕获量之间的关系。结果发现,当地优势害鼠最大活动距离(TBS保护辐射半径)超过100 m;R-TBS、L-TBS(60m)、L-TBS(30 m)的鼠害控制效果分别为84.57%、77.26%、66.77%,在保护辐射范围内(r=100 m)单位面积玉米产量与对照区产量差异不显著。但可挽回损失755、744、713 kg/hm2。通过计算其投入产出关系,建议东北地区玉米地每3 hm2使用一个60 m长的LTBS进行害鼠防控。
In this paper, the control effects of 20 m × 20 m TBS (T-TBS) and linear TBS (L-TBS) of 60 m and 30 m in maize field in Gongzhuling City, Jilin Province, were measured to protect the radiation radius and its control Economic benefits of rats. Based on this, the relationship between maize yield and L-TBS capture was evaluated. The results showed that the maximum activity distance (TBS) of local dominant pests exceeded 100 m; the control effects of r-TBS, L-TBS (60m) and L-TBS at 30m were 84.57% and 77.26% , 66.77% respectively. There was no significant difference in yield per unit area of corn between the protected area and the control area (r = 100 m). But can recover the loss of 755,744,713 kg / hm2. By calculating the relationship between inputs and outputs, it is suggested that a 60 m long LTBS should be used to prevent and control pests in every 3 hm2 of maize field in Northeast China.
