摘要
在耕地上建立放牧型人工草地并进行了观测分析 ,以探讨其利用方法。结果表明 ,推迟播种期可减轻一年生杂草的危害 ,但当年产草量较低 ;草地建植初期 ,草地质量较在原有草地上重建的草地差 ,但通过放牧或刈割后 ,草地质量迅速提高 ;第二年播种牧草长势好 ,杂草少 ,成为一片优质高产的放牧型人工草地。
The grazing type sown grassland was established on cropland and its management and utilization were proposed. The results showed that late seeding time could lighten encroachment by annual weeds, but the pastural yield was lower in the same year. In early stage of established grassland on cropland, there was poor quality than established on old pasture land. However, its quality became better quickly after grazing and cutting. In next year, the new grassland were going well, better growth and less annual weeds.
