摘要
羊群在受到蛴螬严重为害的草地上宿营,对蛴螬数量有显著的控制作用,并能有效地改善土壤养分状况,促进受害牧草根系恢复生长,从而有利于草地植被的复壮更新,因而是一种廉价、有效、易行的草地管理技术。研究结果表明,对蛴螬的控制效果随载畜率的提高而增强,而就草地恢复情况而论,以载畜率为4000~5000只羊/公顷、连续宿营4天的处理效果最为显著。
Sheep night penning on pasture infected by grass grubs strongly controlled the grass grub population and was helpful to the rccovery of the grub-damaged pasture in the camping area by improving soil nutrient availability and root-soil contact.Mob night penning has proved to be a cheap, efficient and practical technique of pasture manage-ment.This study suggested that effectiveness of grub control by night penning in-creased with the increase in instocking rate. Inview of pasture recovery,the stocking rate of 4000~5000 sheep/ha for 4 nights had the best result.
