| 摘 要： | 结合宁夏南部山区的生长条件,在梯田和坡耕地两种地势条件下,设置不同比例的牧草混播组合,测定牧草群体的生长性状、地上生物量和营养成分等指标,对宁南山区苜蓿和羊草混播种植进行研究。结果表明：梯田种植的紫花苜蓿和羊草的株高和茎叶比均高于坡耕地;坡耕地的地上生物量高于梯田;梯田条件下紫花苜蓿与羊草混播比例为3∶2时紫花苜蓿的饲用价值较好,坡耕地条件下紫花苜蓿与羊草混播比例为2∶1时羊草的饲用价值较好。本研究筛选出最适宜宁夏南部山区种植牧草的混播比例,为宁南地区紫花苜蓿和羊草人工混播草地的改良建植积累基础数据。

| Abstract: | The purpose of this study is to explore the mixed sowing technology of alfalfa and Leymus chinensis in the mountainous areas of southern Ningxia.Combining with the growth conditions in the mountainous areas of southern Ningxia,in the two kinds fields of terrace and slope farmland, experiment on two species of grass mixed with different proportions were set up, and traits related to forage growth, above ground biomass and nutrient classification index were measured in groups.The results showed that plant height and stem leaf ratio of alfalfa and Leymus chinensis planting in terrace were higher than those of slope farmland; However,the biomass of slope land was higher than that of terraced field; Nutrition quality of alfalfa and Leymus chinensis showed that the feeding value of alfalfa was better when the alfalfa and Leymus chinensisin terraced field were sowed with a mixed ratio of 3:2; But the feeding value of Leymus chinensis was better when the alfalfa and Leymus chinensisin sloping farmland were sowed with a mixed ratio of 2:1; This study selected the most suitable mixed ratio for planting forage in mountainous area of southern Ningxia, and accumulated data for alfalfa and Leymus chinensis artificially mixed sowing in mountainous area of southern Ningxia. |
