Title: Study on the Yield-increasing Effect of Multi-cropping Vicia Villosa after Wheat
Abstract: The experiment was carried out at Dalate County and two kinds of green manure crops(hairy vetch and common vetch)were cropped after wheat.The results were as the followings: The yield of hairy vetch(Vicia villosa Roth.) and common vetch(Vicia sativa L.) was 23.8 t/hm2 and 20.1t/hm2 respectively when they were ploughed down in the first autumn.In the following year,when the N fertilizer was decreased by 30% the yield of wheat decreased by 4.4% and 5.8% if the hairy vetch and common vetch were cropped in the last year and decreased by 10.1% if without any green manure.When the N fertilizer was decreased by 60% the yield of wheat decreased by 15.6% and 13.7% if the hairy vetch and common vetch were cropped in the last year and decreased by 17.6% if without any green manure.So the green manure cropping could increase the N supplying of the soil.
