通过在不同年限的造林地内设立样地，以实施林粮间作的地块为实验组，没有实施林粮间作的地块为对照组，记录被害率和捕鼠率，运用数理统计的ｕ检验法和ｔ检验法，对两组数据进行统计分析。实验结果表明，实施林粮间作对控制森林鼠害的发生及减小危害都有一定的作用。 By setting up plots in afforestation land with different years, plots of forest intercropping were taken as experimental group, plots without intercropping forest as control group, the rate of victimization and the rate of rat catching were recorded, and the u test method of mathematical statistics And t test, the two groups of data for statistical analysis. The experimental results show that the intercropping of forest and grain has a certain effect on controlling the occurrence of forest rodent and reducing the harm.
