| 摘 要： | 采用叶面喷施的的方法研究了不同施锌水平200，500和800mg／kg对紫花苜蓿（Medicaco sativa）干草产量及品质影响。结果表明：喷施硫酸锌显著（P〈0．05）提高苜蓿草产量，其中施锌量为500mg／kg的处理产量最高。适量的锌水平可以显著提高粗蛋白含量，施锌量为500mg／kg时，可以显著提高紫花苜蓿粗脂肪、粗纤维、磷的含量，对粗灰分含量影响不大。喷施不同浓度Zn处理，除第1茬外，苜蓿中的钙含量有增加趋势。营养物质的年积累量均以施锌浓度为500mg／kg时达到最高。

| Abstract: | The effect of different levels of zinc sulfate on grass yield and quality of alfalfa through leaf surface spurting was studied.The result indicated that the treatment could remarkably(P<0.05) increase the grass yield of alfalfa,in which,the effect of treatment with 500 mg/kg was the best.Proper concentration of Zn could significantly increase the content of crude protein.Treatment with 500 mg/kg of Zn could remarkably enhance the content of crude fat,crude fiber and phosphorus except crude ash.The content o... |
