【Abstract】 The results of apprximate chemical analysis and botanical composition of Nan-jing wild grasses from April to September were presented.The moisture contentwere between 76—85%(avarage 80%).The content of crude protien and etherextract on dry matter basis decreased in August and September.There were on-ly small defferences in monthly figures of nitrogen-free extract.But the crudefibre increased from 15% in April to 35% in August.In April and Mawr,the Nanjing wild grasses contained a wide variety of spe-cies.After May,the gramincal grasses formed the major portion of wild grasses.更多还原
