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。①在牧草上施用稀土,无论用哪种方法(包括浸种、拌种、叶面喷施)年际间总的趋势是一致的,即提高了发芽率,提早出苗1～2天,促进苗期生长,可增产鲜草5.9%～11.4%,对糖份和蛋白质含量在一定的浓度范围内有提高的趋势。②常用的浸种、拌种和叶面喷施均可在牧草上使用,栽培牧草的浸种或拌种加叶面喷施效果最好。③试验证明不同牧草对稀土浓度的要求不一
In different growth stages of several forages, different methods were used and different concentrations of rare earth solutions were applied to test. It was observed that rare earth had a significant effect on the growth and development of forage grass. ① The application of rare earth in forage grass, regardless of the method used (including soaking seed, seed dressing, foliar spray) the interannual trend is the same, that is to improve the germination rate, early emergence 1 to 2 days to promote seedling Growth, can increase the yield of fresh grass 5.9% ~ 11.4%, sugar and protein content in a certain concentration range trend to increase. ② commonly used seed soaking, seed dressing and foliar spray can be used on the forage, planting grass soaking or seed dressing and foliar spray best. ③ test shows that different forage on the concentration of rare earth requirements vary
