| 摘 要： | 为科学施用绿肥,改良酸性土壤,采用尼龙袋法研究了施用豆科绿肥尖叶木蓝(Indigofera zollingeriana)、铺地木蓝(Indigofera spicata)、扁豆(Lablab purpureus)与链荚豆(Alysicarpus vaginalis)后,酸性土壤有机磷在1年内的动态变化.结果表明:4种绿肥均可显著增加土壤有机磷的总量,但尖叶木蓝的效果最好,铺地木兰的最差.链荚豆对土壤活性有机磷的提升效果最好,铺地木蓝的效果最差;尖叶木蓝对中等活性有机磷的提升效果最好,铺地木蓝的效果最差;4种绿肥均可显著降低土壤中稳性有机磷的含量,以铺地木蓝的幅度最大,尖叶木蓝的次之,其余2种最小;对于高稳性有机磷,以尖叶木蓝处理的含量增加幅度最大,其余3种在不同施肥阶段表现各异.在施肥时间方面,以施肥30 d效果最为显著,随后因绿肥种类的不同而有所差异. |

| Abstract: | In order to amend acid soil by the rational application of green manures, a nylon bag method was used to research the dynamic change of total organic phosphorus and the contents of organic phosphorus fractions in acid soil during one year period after apply 4 tropical green manures (Indigofera zollingeriana, Indigofera spicata, Lablab purpureus, Alysicarpus vaginalis). The results indicated that the application of 4 green manures could increase the total content of soil organic phosphorus, the effect of Indigofera zollingeriana treatment was the best and that of Indigofera spicata treatment was the worst compared with others. The increase of soil labile organic phosphorus content was the most after the application of Alysicarpus vaginalis and was the least after the application of Indigofera spicata, whereas the increase of soil moderate labile organic phosphorus content was the most after the application of Indigofera zollingeriana and was the least after the application of Indigofera spicata. The decrease of soil moderately resistant organic phosphorus content after the application of Indigofera spicata was more than that after the application of Indigofera zollingeriana. The content of soil highly resistant organic phosphorus had the most increase after the application of Indigofera spicata, and decreased differently among different periods after the application of the other green manures; and the contents of soil organic fractions were also different among application periods. The apply effects of green manures were the largest after 30 d, and then differed from different green manures. |
