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
preduction of herbage and improved the qtiality 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 sativa,the local Arena Vicia ave-na,Vicia sativa+locaI Avena 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.
