| 摘 要： | 稀土是一种微肥,系镧系元素,在牧草上应用还是一项新课题。本试验是用不同浓度的稀土溶液浸种观其对种子萌发的影响及叶面喷施对牧草产量的影响。试验结果以100ppm浓度浸种发芽效果最好。叶面喷施增产效果:高浓度比低浓度好,特别是对豆科牧草效果尤为显著,可提高产量40—80％。

| Abstract: | Rare-earth element fertilizer (REEF), mainly containg lanthanum (La) element, is a kind of microfertilizers. The apllication of REEF to grassland is also a new study. The effects of seed-soaking into different concentration solutions of REEF on germination oF forage seeds and leaf-spraying at differdnt ppms on enhancing yield of forages were investigated in this experiment. The results showed that the highest germination rate was obtained by soaking seeds into 100 ppm solution. The effect of leaF-spraying of REEF at high concentration on enhancing yield was more significant than that at low concentration, especially,this effect was highly significant in legumes. The yield of legumes were increased by 40-80%. |
