摘要
在几种牧草不同生长期,采取不同的使用方法,施入不同浓度的稀土溶液进行试验,观察到稀土对牧草的生长、发育有明显的影响,可以提高种子发芽率,增加鲜草产量,糖份和蛋白质含量也有增加的趋势。通过试验摸索出了稀土在不同牧草上的最佳使用方法和浓度范围。
Adopting different using methods and applying different concentration of rare-earth elements in different growth periods of several forage crops, we saw distinct effects, such as the increasing in germination rate,in fresh grass yields, in sugar and protein contents etc., Meanwhile we found the optimum using methods and the rang of concentrtion of rare-earth elements for forage grasses.
