| 摘 要： | 通过对1—9年生红豆草地的观测表明,随着红豆草生活年限的增长,土壤有机质及氮、磷全量养分逐年提高,土壤容重,比重和坚实度递减,而土壤孔隙度,水稳性团粒递增。显示出红豆草具有改善土壤理化性状,提高土壤肥力,增加土壤养分储量,增强养分供应强度的良好作用,但红豆草利用年限以五年为宜。

The Effects of Sainfoin on the Physicochemical Properties of Soil |
| |
| Abstract: | It was shown by two-year observation of sainfoin pastures aged from one to nine years that with the development of saiufoin pasture in age the soil fertility and the amount of full-nutrients of nitrogen and phosphorus as well as the soil porosity and water-stable granules increased,while the soil density,specific gravity and compacness decreased, the result proved that sainfoin could play quite a good role in improving the physicochemical properties,raising soil fertility,making the amount of the soil nutrients reseve larger and turning nutrient supply for plants into a better condition,The optimum lengh for sainfoin pasture is about five years. |
