Effect of different mulching methods on soil and water loss in young rubber plantation intercropping with pineapple in Yunnan
摘要
Abstract
The effect of different planting and mulching methods on soil and water losses in young rubberpineapple intercropping plantation was studied in order to provide basis for application of integrated intercropping technolo gy in Yunnan rubber plantations. [MethodjA split-plot experiment with two factors (pineapple planting method as main plot and mulching method as sub-plot) was carried out in young rubber plantation in Xishuangbanna, Yunnan from 2009-2010 to study the surface water runoff and soil erosion in different treatments. In main plots two types of pineapple planting (longitudinal and cross ridge) and in subplot two types of mulching (rice straw and plastic film) were applied. [Result]Planting pineapple in cross ridge decreased the runoff for 4 months (May to August) and soil erosion for 6 months (May to October) in young rubber plantation compared to planting in longitudinal ridge. Total runoff and soil erosion were also reduced in rainy season (April to October). The fields mulched with rice straw decreased the water runoff from April to September and those mulched with plastic film decreased erosion in May, July to October. The total water runoff of soil in plastic film mulched plots was more than in those plots mulched with rice straw. However, the total soil erosion was lesser in plots mulched with plastic film than in those plots mulched with rice straw. [Conclusion]In young rubber plantation, pineapple intercropping in cross ridges was found to prevent the soil and water loss. Kunoff of soil mulched with plastic film was found to be decreased more in comparison to that mulched with rice straw.关键词
