| Abstract: | Comparasion experiments on the different fertilization.Use the whole comparasion among the indexes such as the plant height.branch,yield and water use efficiency.We can get the conclution that the optimum getting fertilizer in Dingxi is the Urea 22.5kg/hm2.P2O5kg/hm2 and K2O4 65.48kg/hm2.And the plant height is 73.4cm.The branch is 4.4.The yield is 896.18kg/hm2.The water use efficiency is 5.38kg/hm2.mm. |
