| Abstract: | In this paper,17 kinds of mineral element including N,P,K,Ca,Mg,S of 24 kinds of Gramineae green manure were analyzed.The results showed that the congtent of N,P,K was in the middle with high fiberization.According to the classification criteria(National Agri-tech Extention Center of China,1999),4.2%,50.0% and 45.8% could be classified as grade 1,grade 2 and grade 3,respectively.Also,Gramineae green manure was rich in mineral nutrient content,but low in heavy metal content,so Gramineae green manure was a sa... |
