鼠害在稻田为害日益严重,在单季杂交稻田主要表现为剪株为害。选用8种检测剪株分布型方法进行测定,发现剪株的分布均属聚集型。通过分析,提出了产量损失调查计算方法,以及防治鼠害的指标确定。
Rodents in the rice fields increasingly serious damage in the monsoon hybrid rice fields mainly for the shear strain damage. Eight kinds of test methods were used to determine the distribution of the cut plants. The distribution of the cut plants was found to be aggregated. Through the analysis, the calculation method of yield loss investigation and the determination of the index of prevention and control of rodent pests were put forward.
