Problems solved by technology

Considering that the dry ash of the straw-sweeping power plant itself is alkaline, the utilization rate is low in alkaline soil. After adding caustic soda and other extractants, the sudden utilization rate will undoubtedly be further reduced; and the alkaline price is expensive, and the energy consumption of roasting is huge, so also greatly increased production costs

Abstract

The invention provides a special silicon-rich compound fertilizer for rice based on power plant dry ash. The special silicon-rich compound fertilizer comprises a nitrogen fertilizer, a phosphorus fertilizer, a potassium fertilizer and the power plant dry ash subjected to acid leaching treatment, wherein the content of N in the compound fertilizer is 15-20 wt%, the content of P2O5 is 10-15 wt%, the content of K2O is 10-15 wt%, and the content of effective Si is at least 4 wt%. The special silicon-rich compound fertilizer for the rice based on the dry ash of the power plant can provide rich effective silicon element nutrition, is suitable for being used by various types of soil, and is simple in production operation and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special silicon-rich compound fertilizer for rice based on power plant dry ash and a preparation method thereof. Background technique [0002] Rice is the first of the three major grains in our country. It occupies a dominant position in our grain production and consumption and is the cornerstone of national food security. Rice is a typical silicon-loving crop and has a large demand for silicon. Studies have shown that after rice fully absorbs silicon, the plants will be stronger, the strength of the stem will increase, and the ability of rice plants to resist diseases and insects will be enhanced, and the resistance to water and mineral nutrient transport will be enhanced. obviously decased. [0003] Although silicon is the second largest element that makes up the earth, in fact, the total silicon content in soil is about 31%, of which about 99% are in crystalline and amo...
