Problems solved by technology

[0004] At present, the use of wet-flush soil in river terraces to grow potatoes cannot accurately determine the amount of nitrogen, phosphorus, and potassium fertilizers required according to the fertilization capacity of the wet-flush soil, which may easily lead to blind fertilization and excessive fertilization. The problem of low yield

Abstract

The invention provides a formulated fertilizer for planting of potatoes in damp soil of a river terrace.The formulated fertilizer is prepared from 4,800-6,000 kilograms / mu of high-quality farm manure, 30-38 kilograms / mu of ordinary urea, 36-42 kilograms / mu of ordinary superphosphate and 22-26 kilograms / mu of potassium sulfate.According to the formulated fertilizer for planting of the potatoes in the damp soil of the river terrace, the fertilizer utilization rate is increased by means of matched application of nitrogen, phosphorus and potassium and organic and inorganic combination according to the fertilizer providing capacity of the damp soil, and therefore the yield of the potatoes is effectively increased.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a formula fertilizer and a fertilization method for planting potatoes in river terrace wet-flush soil. Background technique [0002] my country's fluvo-aquic soil is widely distributed and has a large area. The fluvi-aquic soil area has flat terrain, thick soil layer, good production properties, and is suitable for planting a variety of crops. However, the fluvo-aquic soil developed with clayey sediments has a heavy texture, poor permeability and tillability, stagnant water in the upper layer when it is wet, and cracks and escapes moisture when it is dry. The suitable cultivation period is short. Although the nutrient content is high, the physical properties are poor. Production potential is difficult to realize. [0003] Potatoes are one of the main food crops after rice, wheat and corn. The planting area of ​​potatoes in my country is about 80 million mu in recent years, r...
