Technology for preparing soil repairing agent containing multiple elements

Abstract

The invention relates to a technology for preparing a soil repairing agent containing multiple elements. The soil repairing agent comprises, by weight, 30-70 parts of a bioorganic fertilizer, 0.5-1 part of composite Bacillus subtilis, 10-25 parts of a nano-porous mineral repairing agent, 5-10 parts of potassium fulvate and 5-20 parts of bentonite. The invention also provides a multifunctional soilrepairing agent. The multifunctional soil repairing agent comprises, by weight, 5-10 parts of the composite Bacillus subtilis, 20-50 parts of the nano-porous mineral repairing agent, 10-20 parts of chelated medium trace elements and 5-20 parts of bentonite. Compared with soil repairing agents in the prior art, the soil repairing agent prepared in the invention has the ability to improve the micro-ecology of soil, improve the functions of beneficial bacteria in the soil, improve soil hardening and regulate and buffer the pH value of the soil, also can comprehensively supplement the medium trace elements in soil, promote the growth of roots and comprehensively improve the fertilizer utilization rate, and can significantly reduce environmental pollution and improve the safety of foods and the quality of crops.

Description

technical field [0001] The invention relates to the fields of soil conditioners and fertilizers, in particular to a preparation process of a soil remediation agent capable of improving soil compaction and soil micro-ecological environment balance, and having the functions of soil remediation and anti-heavy cropping. Background technique [0002] Since the introduction of chemical agriculture, especially the mass production and use of chemical fertilizers, agriculture has developed rapidly, meeting the supply of food and the needs of a large number of materials. However, the efficiency of chemical fertilizers produced with high energy consumption is very low in the process of use, such as Plants can only absorb and utilize 20%-30% of chemical fertilizers applied in conventional ways, and 70%-80% of chemical fertilizers are wasted. Therefore, excessive use of chemical fertilizers is often used to provide continuous nutrients for plants to absorb and grow, which is both Cause h...

[0002] Since the introduction of chemical agriculture, especially the mass production and use of chemical fertilizers, agriculture has developed rapidly, meeting the supply of food and the needs of a large number of materials. However, the efficiency of chemical fertilizers produced with high energy consumption is very low in the process of use, such as Plants can only absorb and utilize 20%-30% of chemical fertilizers applied in conventional ways, and 70%-80% of chemical fertilizers are wasted. Therefore, excessive use of chemical fertilizers is often used to provide continuous nutrients for plants to absorb and grow, which is both Cause huge economic losses and easily lead to serious pollution of soil, air and water environment

[0003] The excessive use of chemical fertilizers and the unreasonable phenomenon of agricultural fertilization structure lead to soil compaction, serious acidification, and micro-ecological environment imbalance. Soil compaction hinders the rooting of crops, reduces the utilization rate of fertilizers, makes it difficult for crops to breathe, and hinders the growth of crops, eventually leading to crop yields. decline

[0004] In summary, the existing soil remediation agents and chemical fertilizers still have problems such as low utilization rate and poor soil remediation ability. Therefore, it is necessary to develop a new remediation agent for improving and repairing soil to further promote the utilization rate of chemical fertilizers and improve Soil environment, promoting the healthy growth of crops
