摘　　要：在彬县渭北黄土高原丘陵沟壑区,以常用绿化树种侧柏、刺槐为材料,在不同坡向设置单因素对比试验,进行了"深坑栽植鼠兔无害化控制与应用技术"控制和减轻鼠兔危害效果试验,结果为"深坑栽植鼠兔无害化控制与应用技术"可将侧柏幼树受鼠兔的危害率由常规技术的25.2%~25.9%降低到1.4%~3.8%,幼树死亡率由常规技术的18.0%~20.3%降低到0.2%~1.1%;刺槐幼树受鼠兔的危害率由常规技术的25.0%~29.7%降低到1.6%~2.9%,幼树死亡率由常规技术的10.0%~22.7%降低到0.7%~1.6%,在减轻鼠兔对侧柏、刺槐幼树的危害及其引起的死亡方面作用极显著,且不受树种、坡向等因素影响。In north loess plateau of Wei river,Platycladus orientalis and Robinia pseudoacacia are often applied for afforestation in different slopes of different directions.The deep pit planting technology was applied for experiment on the control Ochotona damage.The result showed that the technology can reduce the Ochotona damage to Platycladus orientalis from 25.2%~25.9%to 1.4%~3.8%and young tree death rate from 18.0%~20.3%to 0.2%~1.1%.Of Robinia pseudoacacia,the damage caused by Ochotona reduced from 25.0%~29.7%to1.6%~2.9%and young tree death rate from10.0%~22.7%to 0.7%~1.6%.The effect to control Ochotona damage was significant regardless of the tree species and slope directions.
