| Abstract: | After plantmg two-year-living Melilotus offcinalia in shallow dryland of Qinghai,the contents of organic matter,tatal nitrogen and hydrolysable nitrogen increased 19.13%,14.20%,12.63% respectively.The contents of available P and K decresed 9.13% and 10.28% respectively.It suggested that increasing P and K fertiliers was able to improve soil fertility,melorate soil and prevent water and soil deteriorism during planting Melilotus offcinalia. |
