【摘要】 本文通过测定人工草地坡面上、中、下部土壤水分动态与牧草生长状况,研究牧草生长与土壤水分的关系,着重分析在干旱情况下对牧草生长不利的影响,从而为牧草抗旱保苗、安全越夏、创建高产稳产人工草地提供科学依据.更多还原

【Abstract】 Experiment was carried out to study the relationship between the herbagegrowth and soil water by means of determining the dynamics of soil waterand the state of herbage growth on the upper,middle and lower parts of theslope surface of artificial grassland.The focus of analysis was put on theunfavourable effect on the herbage growth under dry condition.Thus a scientificwas provided for the practice of protecting herbage seedlings from draught andsummer season and of establishing an artificial grassland with high andstable yield.更多还原
