Abstract
A field experiment was done in Chifeng city to study the effect of different green manures on the soil fertility quality.The results showed that Medicago sativa,Melilotus suaveolens and Astragalus adsurgens could improve soil quality.Among the three green manure treatments,the soil improvement effect of them was in the order of Astragalus adsurgens ＞ Medicago sativa ＞ Melilotus suaveolens.Compared with leisure treatment,after returning of astragalus adsurgens,the soil organic matter content,total nitrogen content,effective phosphorus content and instant potassium content were increased by 0.3 g/kg,0.05 g/kg,0.8 mg/kg and 7mg/kg respectively.关键词
