| 摘 要： | 在干旱半干旱地区对草地进行水分生态学研究有重要意义,笔者曾对此提出过一些见解,并做过一些工作。本文旨在从人工草地苜蓿(Medicago sativa)种群地上生物量动态方面考察,为合理管理和利用苜蓿人工草地提供科学依据。

| Abstract: | Regression analysis on Medicago sativa Population biomass and relative growth rate(RGR) versus environmental elements are made, and several regression equations are obtained. Through analysis of regression equations and local environmental conditions, it is believed that harvesting the aboveground biomass of Medicago sativa once in late July and letting it continuous growing, it will be beneficial to the increase of productivity and the maintenance of water balance of the artificial grassland. |
