| 摘 要： | 为了评价纳米型植物抗逆剂（NPA）侧柏蘸浆造林的抗旱与控制鼠（兔）害作用，以多效抗旱驱鼠剂（RPA）为参照，采用NPA和RPA比较了不同地区侧柏蘸浆造林的整体效果。结果表明，干旱和鼠（兔）害是林木致死的关键因素。其中，定植当年干旱、鼢鼠和草兔致死率占总致死比例分别为55.6%～71.1%、10.1%～17.6%和15.0%～24.2%；定植3 a分别占47.6%～73.5%、9.7%～17.5%和15.0%～33.6%。草兔和鼢鼠成为麟游点侧柏致死的首要因素。定植当年NPA蘸浆造林对干旱致死预防效果为65.2%～73.0%，比RPA增加了41.7%～53.9%；定植3 a的为75.6%～83.5%，比RPA高12.5%～20.6%；两者差异极显著。定植当年NPA、RPA对鼢鼠预防效果为92.5%～100.0%和84.7%～100.0%，差异不显著；定植3 a对鼢鼠预防效果为88.8%～97.0%和75.9%～86.3%，米脂和宝塔点差异显著。定植当年NPA对草兔预防效果为91.8%～100.0%，比RPA提高0.0%～7.6%；定植3 a NPA草兔预防效果为88.9%～97.3%，比RPA高9.0%～11.3%。其他致死因素对米脂和宝塔点鼢鼠和草兔致死预防效果影响较大，其均值变异率远超5%的统计允许要求，数据分析时必须剔除其干扰。

| Abstract: | The formation of a young plantation is a key stage to determine the success or failure of afforestation. In order to evaluate the effects of NPA on drought resistance and rodent control in the afforestation of Platycladus orientalis with the method of dipping the seedling roots in soil slurries mixed with NPA. The application of RPA was used as a control. The results showed that the drought and the rodent damages were lethal key factors to P. orientalis seedlings. One year after planting, the ratios of fatality rates to the total mortality were 55.6%-71.1%, 10.1%-17.6% and 15%-24.2% caused by rought, zokor and Lepus capensis, respectively. The ratios were. 47.6%-73.5%, 9.7%-17.5% and 15%-33.6%, respectively 3 years after planting. L. capensis and zokor became primary factors to the death of the seedlings in Linyou. The drought prevention effect of applying NPA in the first year was 65.2%-73.0%, 41.7%-53.9% higher than applying RPA, 75.6% to 83.5% in the third year, 12.5%-20.6% higher than applying RPA, and the difference was significant. The zokor prevention effects of applying NPA and RPA were 92.5%-100.0% and 84.7%-100.0% in the first year with no significant difference, and 88.8%-97.0% and 75.9%-86.3% in the third year with significant differences in Linyou and Baota. The L. capensis prevention effect of applying NPA was 91.8%-100.0% in the first year, 0.0%-7.6% higher than applying RPA, 88.9%-97.3% in the third year, 9.0%-11.3% higher than applying RPA. |
