摘　　要：为改善退化人工草地优质牧草生长条件 ,对杂草、蛴螬危害引发的退化草地 ,进行低成本免耕改良试验。结果表明 :化学除杂、全日制放牧免耕补播与常规法 (耕作重播 )均能改善人工种植牧草生长环境 ,杂草、蛴螬数量明显降低 ;两种免耕补播比常规法重播成本分别降低54.1% ,64.3% ;改良草地优质牧草覆盖度、组分。Aim of this low cost pasture renew trial is to improve the condition of pasture growing in deteriorated pasture caused by weeds and pasture grub. The results found that: apply herbicide+oversowing, 24h grazing+oversowing can increase pasture density and production and improve pasture competition, compare with cultivation, the cost was reduced by 54.1% and 64.3%.
