AI Technical Summary

Problems solved by technology

Such chemical fertilizers have the following defects: flowing with water, resulting in waste of fertilizers, making the fertilizers not well absorbed by crops, and the utilization rate of fertilizers is only 30%-35%
This will further cause the following hazards: first, it will pollute the groundwater, and the lost fertilizer will reach the groundwater layer through leakage, causing serious pollution to the groundwater; second, it will cause soil compaction, affect the air permeability of the soil, and then affect the respiration of the roots. Affect crop growth and reduce crop yield; increase the frequency of deep plowing and increase agricultural production costs

Abstract

The invention belongs to the technical field of high-efficiency anti-seepage fertilizer, and discloses a high-efficiency anti-seepage fertilizer and a preparation method thereof. The high-efficiency anti-seepage fertilizer is mainly technically characterized by comprising the following materials in parts by weight: 1000 parts of powdered basic fertilizer, 1-3 parts of non-ionic polyacrylamide, and 1-4 parts of polyaspartic acid. The fertilizer and soil are adsorbed to form a cluster particle structure so as to be adsorbed at the roots of crops, so that seepage does not easily occur, the loss of water and fertilizer can be avoided, the permeability, water retention property and fertilizer retention property of soil can be greatly increased, the caking of the soil can be prevented, the water and fertilizer utilization rate can be improved, and the production cost of crops can be lowered, and the pollution of the fertilizer to underground water can be reduced.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency anti-leakage fertilizers, and in particular relates to high-efficiency anti-leakage fertilizers and a preparation method thereof. Background technique [0002] Most of the base fertilizer before crop planting and additional chemical fertilizers during the growth process use ordinary chemical fertilizers. The chemical fertilizers in the soil are dissolved in water, and the fertilizers migrate with the water under the leakage and flow of water. Such chemical fertilizers have the following defects: flowing with water, resulting in waste of fertilizers, making the fertilizers not well absorbed by crops, and the utilization rate of fertilizers is only 30%-35%. It not only causes waste of fertilizer, but also increases the cost of agricultural production. In order to increase crop yields, farmers generally use more additional fertilizers. This will further cause the following hazards: first, i...
