种植年限对胡椒园土壤化学肥力指标的影响

Effects of the Planting Period on the Soil Chemical Fertility Parameters in Pepper Garden

系统探讨了不同种植年限胡椒园土壤化学肥力指标的变化状况,结果表明:随种植年限的推移,上层土壤有机质和全氮、土壤有效锰含量明显下降,有效硼与下层土壤有效铜含量明显上升,部分养分含量有下降趋势,须通过强化土壤养分管理、改进施肥方式等措施,阻止老龄胡椒园部分养分继续下降。

This paper was aimed to explore the variation of soil chemical fertility parameters of the planting period in pepper garden. With the planting period lengthened, the amount of soil organic matter, total N and available Mn were reduced remarkably on the 0-20 cm layer, while the amount of available Cu on the 20-40 cm layer and available B were increased, and some of the soil chemical fertility parameters got worse. In order to change these, it was necessary to apply fertilizers rationally, strengthen soil nutrient management and improve management practice.
