Fertilizer synergist capable of promoting soil to release effective elements and preparation method thereof

Abstract

The invention relates to the technical field of fertilizer, in particular to a fertilizer synergist capable of promoting soil to release effective elements and a preparation method thereof. The fertilizer synergist is prepared from, by weight, 25-35 parts of humus acid, 15-25 parts of alginic acid, 25-35 parts of lotus fermentation enzyme and 15-25 parts of water, wherein the lotus fermentation enzyme is prepared by lotus fermentation and microelement chelation. The lotus fermentation enzyme with microelements through chelation and organic matter generated after a crosslinking reaction of the humus acid and the alginic acid under the effect of ethylenediaminetetraacetic acid are adopted as the fertilizer synergist, under the excitation of water in soil, activity is brought into play, complexation of calcium, magnesium and iron released in the soil is performed to form substances such as organic calcium, organic magnesium and organic iron capable of being absorbed and utilized by crops, and then phosphates formed by binding of metals such as calcium, magnesium and iron release phosphate radicals, so that phosphates which are hard to dissolve and abundant in soil become soluble or citric-soluble phosphates, and the obtained phosphates are absorbed and utilized by plants.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a fertilizer synergist for promoting the release of effective elements from soil and a preparation method thereof. Background technique [0002] Phosphorus is a non-renewable rare resource. In 2009, my country's phosphate rock output was 55 million tons, accounting for 35% of the world's total output of 100 million tons, ranking first in the world. Due to unreasonable "mining the rich and abandoning the poor", the recovery rate of phosphate rock is low, resulting in an annual reduction of more than 130 million tons of phosphate rock resources. The rate of consumption of phosphorus resources in my country is much higher than that of other countries. According to the budget of this consumption rate, it is difficult to maintain economically exploitable phosphate rock resources for another 30 years. If this development is carried out, my country's rich phosphorus rock will be exh...

AI Technical Summary

Problems solved by technology

The current production of high-concentration phosphate fertilizers consumes more than 80% of the phosphate rock resources, most of which are converted into insoluble compounds in the soil in a short period of time or remain in slag and phosphogypsum. The only phosphorus that is actually used in the current season is 10-25%, the use effect and economic efficiency of high-concentration phosphate fertilizer in compound fertilizer are very poor

[0003] Years of high-concentration and large-scale application of phosphorus fertilizers have made most of the soil in my country rich in phosphorus. The average amount of total phosphorus in the soil has reached more than 40 times the crop demand, and a large amount of phosphorus is deposited in the soil in the form of phosphate, causing soil micro Pore ​​blockage, hardening, acidification, affecting crop growth
