Problems solved by technology

At present, problems such as excessive application of chemical fertilizers, unbalanced nutrient supply, coexistence of high yield and low efficiency and low yield and low efficiency generally exist in the production of major crops, especially: heavy nitrogen and phosphorus fertilizers, light potassium fertilizers; heavy macroelements and light trace elements; heavy inorganic fertilizers, "Triple and triple light" phenomenon of light organic fertilizer
Problems such as inappropriate fertilization time and unreasonable application methods restrict the further improvement of potato yield and economic benefits

Abstract

A planting method for improving yield of moisture soil summer potatoes comprises the steps of firstly, selecting a plot; secondly, performing formula fertilization aiming at the fertility characters of the plot; thirdly, preparing the fertilized plot; fourthly, precisely sowing on the prepared plot; fifthly, performing field managing. The applying amounts of a nitrogen fertilizer, a phosphate fertilizer and a potash fertilizer are determined by combining the fertilizer needing characters of the potatoes according to the soil fertility supplying capacity and a target yield, and the crop physiological problem caused by blindness fertilization and excessive fertilization is avoided; organic matter and inorganic matter are combined by the formula applying of N, P and K, ridging planting is adopted for the adhered and heavy soil with an irrigation condition, and the use rate of the fertilizers is improved by combining the intertillage and earth up in the later period, so the aims of improving the potato yield, saving the cost and increasing the effect are achieved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a cultivation method for improving the yield of summer potatoes in fluvo-aquic soil. Background technique [0002] The technology of soil testing and formula fertilization has been widely promoted and applied in recent years. This technology is based on soil testing and fertilizer field experiments, according to the law of crop fertilizer demand, soil fertilizer supply performance and fertilizer effect, and on the basis of rational application of organic fertilizers. And solve the contradiction between the fertilizer needs of crops and the fertilizer supply of soil, and at the same time supplement the nutrients needed by crops in a targeted manner, achieve a balanced supply of various nutrients, meet the needs of crops, and achieve the purpose of improving fertilizer utilization efficiency. [0003] Potatoes are one of the main food crops next to rice, wheat and corn. T...
