通过研测不同土地类型沙打旺草地土壤水分消长动态及水分有效生产率,提出坡地反坡台种植沙打旺,是提高其草产量和自然降水利用率的有效措施。
By measuring the dynamic changes of soil moisture and the effective water productivity of sandy land in the different land types, we proposed that the planting of sand and anti-sloping lands on the sloping land should be an effective measure to increase its grass yield and natural precipitation utilization rate.
