Comparison Test on Fertilization of Potato in Aboveground Ridge Cultivation Model

Most farmers were used to apply mass fertilizer on potatoes,thus,caused nutrient deficiency and single component in soils,and the quality of potatoes was decreased.The test through the ridge aboveground cultivation model,studied the effects of different fertilization treatments on yield,quality and other related traits.The results showed that the treatment using Stabilized Fertilizer ENTEC had obviously improved agronomic characters,yield,vitamin C content,protein content and commodity rate of potato than other conventional fertilization treatments,and the yield and commodity rate were significantly higher than other treatments.Starch content,though,was only 15.03% in the treatment ENTEC,the starch yield in unit area increased due to the increased yield.
