Abstract

The invention provides a water-soluble fertilizer for improving soil quality and a preparation method of the water-soluble fertilizer, and belongs to the technical field of water-soluble fertilizers. The water-soluble fertilizer consists of the following components: calcium carbonate, potassium silicate, calcium sulfate, sodium sulfate, ethylenediamine tetraacetic acid, bacillus licheniformis, bacillus subtilis, xylogen, potassium sulfate, urea, 2-chloro-6-nitrapyrin, polyacrylamide, citric acid, compound sugar alcohol, alanine and water. The preparation method is simple and efficient, is low in cost, and has high commercial use value. By the water-soluble fertilizer for improving soil quality, absorption of crops to cadmium can be inhibited; if the water-soluble fertilizer for improving soil quality is irrigated to plants in a dripping manner or sprayed to the plants, absorption and enrichment of the cadmium and mercury in the plants can be reduced, the water-soluble fertilizer can also be uniformly distributed in soil of the roots of the plants by integration of water and fertilizer, requirements of the plants in a growth period to various nutrients can be met, growth of the plants is promoted, the quality of the plants is improved, and maximization of utilization of the fertilizer is realized.

Description

technical field [0001] The invention belongs to the technical field of water-soluble fertilizers, and in particular relates to a water-soluble fertilizer for improving soil quality and a preparation method thereof. Background technique [0002] According to survey statistics, the area of ​​cultivated land polluted by heavy metals in my country has reached 20 million hectares, accounting for 1 / 6 of the total cultivated land area in the country. On average, 12 million tons of grains are polluted by heavy metals every year in my country, causing direct economic losses of more than 20 billion yuan. According to statistics in recent years, the area of ​​cadmium-contaminated farmland in my country has reached 280,000 hectares, and the annual output of cadmium-exceeding agricultural products exceeds 1.5 million tons (Luo Qiong, Wang Kun, Xu Jingbo, Chen Guanghui: "Cadmium pollution status, hazards, sources and production in rice fields in my country measures", "Anhui Agricultural S...
