Effects of Application Nitrogen, Phosphorus and Potassium on Vitamin C Content of Zhuangshu-Ⅲ
In order to improve the vitamin C content of Zhuangshu- Ⅲ, the fertilizer experiment on Zhuangshu- Ⅲ had been set up.The results showed the sort order of the vitamin C content different fertilizer is nitrogen(x1 ) > potassium(x3 ) > phosphorus(x2).The fertilizing plan that the vitamin C content is more than 120.0 mg·kg-1 is pure N 163.41 kg·hm-2-207.96 kg·hm-2, P2O5 98.03 kg·hm-2 ~ 141.97 kg·hm-2, and K2O 79.77 kg·hm-2 ~ 111.66 kg·hm-2.
