| 摘 要： | 在亚热带红壤地区研究有机肥(Ⅰ基肥、Ⅱ基肥+石灰、Ⅲ基肥+猪粪、Ⅳ不施肥)对苜蓿产量及红壤肥力变化的影响。结果表明,在相同的管理条件下,施用有机肥普遍提高苜蓿鲜草产量(P<0.01)。处理Ⅱ增产效果最好,比不施肥处理可提高苜蓿鲜草产量14.52%(P<0.05)。施有机肥可增加土壤pH值、有机质、全氮、全磷、速效氮、速效磷及速效钾的含量(P<0.05),但全钾含量则减少,其中第Ⅲ组提高土壤全量养分和速效养分含量显著高于Ⅰ、Ⅱ组,第Ⅱ组对速效养分的增加高于第Ⅰ组。

| Abstract: | The effects of organic manure on the output of Alfalfa and soil nutrition in red soil were studied.The results showed that applying organic manure could increase the output of Alfalfa(P<0.01)under the same management,and the treatment Ⅱ was the highest,which was more than treatment I by 14.52%(P<0.05).Applying organic manure also enhanced pH value,content of organic matter,total N,P,rapidly available N,P and K of red soil remarkably(P<0.05),whereas the content of total K decreased.Besides,the content of soil nutrition of treatment Ⅲ was remarkably higher than that of treatmentⅠand Ⅱ,and the content of soil rapidly available nutrition of treatment Ⅱ was higher than that of treatmentⅠ. |
