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.
