| 摘 要： | 利用铁、锌、硼和钼等4种微肥,在鸡脚草和百脉根混播草地中进行了应用性研究。研究表明,铁肥和硼肥最有效的利用浓度为6.0×10~(-4),而锌肥和钼肥则为4.0×10~(-4)和8.0×10~(-4)。铁、硼和钼肥能够促进牧草分蘖,提高叶面积指数和提高与杂草的竞争力,有利于牧草的光合作用和提高牧草质量。另外,钼肥和铁肥分别能够提高牧草产量11.84％和7.89％,锌、硼锌分别能够提高牧草种子产量11.96％和9.76％。

| Abstract: | In this study, we compared the effect of four kinds of fertilizers, including Fe, Zn, B, Mo, on the mixture pasture of cocksfoot and birdsfoottrefoil. The results showed that the optimum concentration for Fe and B was 600×10~(-6). While the optimum concentration of Zn and B was 400×10~(-6) and 800×10~(-6), respectively. Fe, B, Mo fertilizer could promote forage tillering, enlarge LAI and strengthen competition ability with weeds, which favored photosynthesis and forage quality improvement. In addition, forage yield was improved by 11. 84% and 7. 89% by using Mo and Fe fertilizer, respectively. For the Zn and B fertilizer, seed yield increased by 11. 96% and 9. 76%, respectively. |
