摘　　要：为探索喀斯特山区旱地施用生物有机肥对黑麦草生长的影响及增产效果,进行了白酒酒糟、奶牛牛粪及猪粪的堆肥发酵及生物有机肥(添加适当比例蚯蚓粪的有机堆肥)对黑麦草生长的影响试验。结果表明:在施用有机堆肥条件下,旱地上黑麦草的出苗率、株高及生物量生长出现明显的增加。施用添加蚯蚓粪的酒糟堆肥、牛粪堆肥、猪粪堆肥处理的地上生物量、地下根重和叶片中氮素含量比未添加蚯蚓粪的有机堆肥处理平均分别增加33.2%、24.4%和12.4%。结论:添加蚯蚓粪的生物有机肥能促进黑麦草的生长及其对氮的吸收,明显提高黑麦草的产量和质量。Waste distiller＇s grains,cow dung and pig dung were composted to study the effects of biological organic fertilizers（adding wormcast） on the growth and yield of ryegrass on the dry land in Karst mountainous areas.The results showed that the germination rate,height and biomass of ryegrass were increased significantly by using the compound fertilizers.Compared with the not adding wormcast treatment,the average overground biomass,root weight and total nitrogen content in leaves were increased by 33.2%,24.4% and 12.4%,respectively.Using the compound fertilizers by adding wormcast could promote the growth and the nitrogen absorption in the leaves of ryegrass so as to raise the grass yield and quality of ryegrass.
