摘要
本文论述了沙地羊柴人工草地土壤水分条件与生产力的关系。在毛乌素沙地,土壤水分条件是限制植被生产力的主要因素;选择抗旱植物种及控制适宜的栽植密度,是提高羊柴人工草地生产力的重要手段。
In this paper, the relationships between the soft moisture and the productivities of sweetvetch (Hedysarum laeve) seeded pastures in sandy lands are descriobed. In Mowusu sandy lands, the soil moisture conditions should be the main factors that influence the productivities of seeded pastures. It is suggested that gigher of the seeded pastures in sandy lands could be obtained when drought resistomt plant species are selected and the density of plomts is controlled.
