摘要: 为改善胶园土壤肥力状况,通过胶园行间挖大通沟(宽×深为100×80cm)施用有机肥(处理Ⅰ)、施用有机肥 薄膜覆盖(处理Ⅱ),以胶园常规管理为对照(CK)。分析5年全量养分、速效养分以及有机质的变化,处理Ⅰ和处理Ⅱ土壤养分含量显著高于CK,每年的养分含量显著高于基础含量;处理Ⅰ和处理Ⅱ中20-40cm土层的养分含量高于0-20cm土层的含量;经过薄膜覆盖的处理Ⅱ土壤养分含量高于处理Ⅰ。施用有机肥明显提高了土壤肥力,土壤养分含量趋势为施用有机肥 薄膜覆盖>施用有机肥>常规管理。

Abstract: To improve soil fertility in rubber plantation, by means of digging big furrow (wide×deep: 100 cm× 80 cm) between lines, soil total nutrients, available nutrients and organic material in five years were studied under the treatments of manure (Treatment Ⅰ) and manure film covering (Treatment Ⅱ), and traditional management (CK) was used as control. The results showed that soil nutrients content of Treatment Ⅰ and Treatment Ⅱ were significantly higher than that of CK, contents of soil nutrients in every year were significantly higher than that of base contents; soil nutrient in 20-40 cm soil layer were higher than that of 0-20 cm soil layer in TreatmentⅠand Treatment Ⅱ; after film covering, soil nutrient of Treatment Ⅱ were higher than that of TreatmentⅠ. The application of manure obviously increased soil fertility, the tendency of soil nutrient followed the order of manure film covering> manure> traditional management.
