Environment-friendly chemical fertilizer capable of improving saline-alkali soil and preparation process of environment-friendly chemical fertilizer

Abstract

The invention discloses an environment-friendly chemical fertilizer capable of improving saline-alkali soil and a preparation process of the environment-friendly chemical fertilizer, and relates to the technical field of chemical fertilizer preparation. The environment-friendly chemical fertilizer is prepared from the raw materials in parts by weight: 80-150 parts of animal waste, 20-40 parts of rice washing water, 20-50 parts of traditional Chinese medicine residues, 100-200 parts of animal bones, 10-15 parts of canal mud, 10-20 parts of ammonium sulfate, 12-20 parts of straw, 30-50 parts ofpurified water, 2-10 parts of boron slag, 10-30 parts of bentonite and 20-30 parts of biological bacteria. According to the environment-friendly chemical fertilizer capable of improving saline-alkalisoil and the preparation process of the environment-friendly chemical fertilizer, the soil structure and permeability can be improved by adding the biological bacteria into the raw materials of the fertilizer, so that the soil is agglomerated without the phenomenon of hardening, saline ions in the soil are enabled to be infiltrated into a deep layer of the soil through pores of the soil, and thenthe purpose of reducing the salinity of the soil is achieved; the pH value can further be lowered, the elemental calcium in the animal bones is infiltrated into the soil to improve the absorption capacity of crops, environmental protection and no pollution are achieved, and an improvement index for the saline-alkali soil can be up to 99%.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizer preparation, in particular to an environment-friendly chemical fertilizer capable of improving saline-alkali soil and a preparation process thereof. Background technique [0002] Chemical fertilizers are referred to as chemical fertilizers. Fertilizers made by chemical and (or) physical methods that contain one or several nutrient elements needed for the growth of crops. Also known as inorganic fertilizers, including nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, micro-fertilizers, compound fertilizers, etc. [0003] Good soil quality plays an important role in agricultural production as an important means to ensure a good agricultural harvest. The main problems in the use of a large amount of chemical fertilizers are the unreasonable use of chemical fertilizers, the serious imbalance of nutrients in the soil, the deterioration of the soil ecological environment...

AI Technical Summary

Problems solved by technology

[0004] A Chinese patent discloses a chemical fertilizer and its preparation method (authorized notification number CN105272445A). This patented technology can increase production and income, improve quality and optimize quality, resist lodging, resist diseases and insect pests, and prevent premature aging; The chemical fertilizers used in this paper do not improve the quality of the soil too much, and cannot improve the soil properties, and cannot make the soil more transparent and granulated, and most of the chemical fertilizers prepared by the prior art are not environmentally friendly. Therefore, those skilled in the art provide a A kind of environment-friendly chemical fertilizer that can improve saline-alkali soil and preparation technology thereof, to solve the problems raised in the above-mentioned background technology
