Abstract

The winter potato fertilizing method capable of reducing sugar content in potato includes the following steps: applying base fertilizer comprising organic fertilizer, coal burning fume desulfurizing side product and / or inorganic fertilizer containing N, P, K, S, Ca, Si, B, Mo and other elements before transplantation of potato seedling; applying inorganic fertilizer for the first time in the initial seedling period; applying inorganic fertilizer for the second time during initial tillering and applying inorganic fertilizer for the third time during the initial blooming period. The said method can reduce the sugar content of potato by 30-50 % while increasing yield of potato, and the starch, protein and vitamin C contents of potato.

Description

technical field [0001] The invention relates to a potato cultivation method, in particular to a fertilization method for reducing the reducing sugar content of winter potatoes. Background technique [0002] Potato is an important grain, vegetable, feed crop and industrial raw material crop. Its planting area is second only to corn among dry food crops, and its total output ranks fourth after rice, wheat, and corn. It is recognized as a nutritious Abundant, delicious agricultural products, and secondly, its processed products, potato chips and French fries, are popular foods all over the world. In recent years, with the continuous expansion of the demand for potatoes in the world market and the gradual deepening of the adjustment of agricultural structure, especially with the gradual understanding of the nutritional value of potatoes and the further improvement of the food structure of urban and rural residents, potato production has become more and more popular. The cultiva...
