Effect of Different Measures for Soil and Water Conservation under Citrus reticulata Stands

摘要: 2015 年6 月,在浙江省临海市选取坡度大于25°柑橘Citrus reticulata 林试验区,建立不同类型水土保持 措施小区。2015 年8 月至2016 年10 月,测定场降雨量大于12.5 mm 的径流量和产沙量。结果表明,从蓄水保土 效果来看,竹节沟+忍冬Lonicera japonica 缓冲带>忍冬>茶Camellia sinensis 缓冲带>不套种。柑橘林下布设不同 水土保持措施的地表径流、泥沙量与不套种间差异显著(P<0.05),且柑橘林下布设竹节沟,同时栽植忍冬等经 济作物,蓄水保土效益明显,且增加了经济效益。Abstract: Sample plots were established with different measures for soil and water conservation in June 2015 at Citrus reticulata stands on slope larger than 25hin Linhai of Zhejiang province. Determinations were made on runoff and sediment yield on daily rainfall larger than 12.5 mm during August of 2015 to October of 2016. The result demonstrated that runoff and sediment yield of treated plots had significant difference with that of the control, the effect of water and soil conservation was ordered by bamboo-shaped ditch+ interplanting Lonicera japonica>interplanting L.japonica>Inter planting Camellia sinensis>control. The experiment indicated that it had great effect of water and soil conservation and even economic benefit to interplant economic crops with bamboo-shaped ditch.
