Optimization of Technical Factors for High Yield Cultivation of Potato

The potato cultivar“Kexin 4”“Zhongshu 5”“Feurita”and“Huang Mazi”,using mixed level orthogonal design.The potato were used different ways of cultivation,in order that we compared the effect of potato of photosynthetic characteristics and identify the best mode of cultivation of the potato yield.Results showed that treatment 10 (Spacing 30 cm,row spacing 80 cm,potato fertilization amount 2 100 kg/hm² or 2 400 kg/hm~2,mulching,drip irrigation spacing of ridge distance fertilization fertilizer amount of potato,film,drip irrigation,foliar fertilizer).The yield and photosynthetic characteristics of the potato were significantly higher than other treatments （P＜0.05） and treatment 10 showed stablly in two years test.
