Analysis of Mineral Nutrients Contents in Grasses in Suniteyou Banner Pasture
The content and the state of sufficiency or lack of N,P,K,Ca,Mg,S,Fe,Mn,Zn,Cu,Mo、Se in 8 styles and 6 types of grassland in Suniteyou banner were analyzed.The results showed that plant community's N content from study area in August was 16.86g/kg;the pasture was rich in Ca but lack of P,and calcium-phosphorus ratio showed imbalanced seriously,so grazing livestock should pay attention to supplement of P;the content of K,Mn,and S in pasture was normal and the content of Fe,Mn was high,so grass nutrients can satisfy the demand of livestock in warm seasons;the content of Cu,Zn,Se was low,so diets should be supplied with them appropriately.The enrichment order of trace elements in different grassland type in study area was River pan and lake basin lowlands salt meadow pasture ＞＞Monadnock sloping steppe desert pasture＞ Hilly steppe pasture＞ Hilly desert steppe pasture ＞ High plain desert steppe pasture ＞ Dune vegetation pasture.
