Compound fertilizer preparation for improving saline alkali soil, and preparation method of compound fertilizer preparation

Abstract

The invention discloses a compound fertilizer preparation for improving saline alkali soil, and a preparation method of the compound fertilizer preparation. The compound fertilizer preparation is prepared from the following raw materials in parts by weight: 3-4 parts of amino acids, 0.2-0.3 part of polyaspartic acid, 4.78-5.66 parts of bio-carbon, 0.3-0.4 part of modified organosilane, 0.5-0.8 part of starch grafted acrylate and 0.02-0.04 part of biological strains. All the components, having unique functions, of the compound fertilizer preparation are enabled to play roles comprehensively; according to long-term practice research and application, the compound fertilizer preparation begins to take effect after being applied to the saline alkali soil for about half a month, and enables theindexes such as pH value and salinity to be significantly reduced after being applied to the saline alkali soil for about two months later. Furthermore, the compound fertilizer preparation can loosenthe soil, reduce soil bulk density, increase soil porosity, fertilize soil fertility, protect fertilizer and water, promote crop growth and the like, and is remarkable in effect.

Description

technical field [0001] The invention relates to two fields, the field of polymer organic chemistry and the field of fertilizer technology, in particular to a compound fertilizer preparation for improving saline-alkali soil. Background technique [0002] The situation of land salinization in China is very serious. According to the materials published by the State Forestry Administration Office and other government departments in 2014, China is one of the countries with the most serious land salinization in the world. According to the results of the national land salinization survey, the area of ​​saline-alkali land in China is 1.48 billion mu, and there are about 260 million mu of potential saline-alkali soil, and nearly 400 million people are affected by land salinization. Soil salinization not only causes soil compaction and decreased fertility, but also seriously affects the absorption of nutrients by crops and hinders crop growth. The importance of improving saline-alkali...
