摘要
试验结果表明,采用合适浓度的稀土溶液浸种可促进牧草的生长发育,提高牧草产量,改善牧草品质。经过二年试验,箭舌豌豆、当地燕麦、箭舌豌豆和当地燕麦混播平均增产分别为29.18%、19.92%和30.00%,稀土浓度应控制在300×10^(-6)～400×10^(-6)之间,是提高一年生牧草产草量的有效技术措施之一。
This experiment was carried out in the alpine meadow.The results showed that the rare elements fertilize not only promoted the growth of herbage and the development of herbage but also increased the production of herbage and improved the quality of herbage by the herbage seeds which were soaked in the suitable rare elements solution.Thyough two yers of test,the average Yields of Vicia satiua,the local Arena Vicia ave-na,Vicia satiua+local Arena have been improred,they were 29.18%,19.92% and 30.00% in order.The range of the contents of the rare elements solution should be controled 300ppm～400ppm,the method motioned above is a effective way of improv-ing the Pasture Yields.
