A field plot experiment was conducted to study the impacts of three planting densities on the yield of Xiangzayou763 under two fertilizer rates(high and low fertilizer rates).The results showed that under high fertilizer rate,the inhibitory effects of increasing planting density on growth of stem and leaf were obviously stronger than that under low fertilizer rate,and the strongest inhibitory effect was on the length and width of leaf,the following was on the diameter of root and stem,the last one was on the number of green leaves;under low f...
