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.
