A field experiment was conducted to study the effects of different planting density and fertilizer rates on dry matter accumulation,chlorophyll and yield of ' Xiangzayou763 '.The results showed that Fertilizer factor was more important than planting density in chlorophyll,dry matter accumulation and yield.The highest yield was 2696.2 kg/hm 2 which fertilizer of N,P2O5,K2O,B were 180,90,157.5,0.9 kg/hm2 and planting density was 7.5×104 plants/hm 2.Chlorophyll-a,Chlorophyll-b,total chlorophyll and dry matter accumulation increased with the inc...
