Hardened soil improvement method

Abstract

The invention provides a compacted soil improvement method, which comprises the following steps: the first step, turning over the compacted soil with a shallow tiller and breaking the soil block with a rotary tiller; The soil improver, and then use the deep tiller to bury the soil improver into the soil; the third step, apply the organic compound fertilizer on the soil surface and use the shallow tiller to bury the organic compound fertilizer into the soil; the fourth step, in the soil Sprinkle the soil conditioner on the surface and cover with 2-3 cm crushed soil, then apply organic compound fertilizer, and finally cover with a layer of 3-5 cm crushed soil. The compacted soil improvement method has fewer steps, less workload and is easy to operate. Brevibacillus lateralosporus and Streptomyces freundii in the soil conditioner used in the compacted soil can multiply rapidly in compacted soil, combined with potassium fulvic acid, can improve Soil aggregate structure, loose soil, improve soil water and fertilizer retention capacity, so as to quickly improve the growth of crops in compacted soil.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a compacted soil improvement method. Background technique [0002] With the increase in the use of chemical fertilizers, no matter how much fertilization and irrigation are increased in many rural lands, the crops will not grow well. In addition to climate factors, it is caused by poor soil aggregate structure and soil compaction caused by long-term application of chemical fertilizers. In recent years, with the improvement of people's awareness of sustainable development and the promotion of the government, more and more scientific research enterprises have begun to study compaction soil improvement methods. Most of the currently commonly used compaction soil improvement methods are complicated in steps, heavy in workload, and inconvenient to operate. In addition, although the existing improvement methods use large soil improvers to improve soil fertility and soil struct...

In recent years, with the improvement of people's awareness of sustainable development and the promotion of the government, more and more scientific research enterprises have begun to study compaction soil improvement methods. Most of the currently commonly used compaction soil improvement methods are complicated in steps, heavy in workload, and inconvenient to operate. In addition, although the existing improvement methods use large soil improvers to improve soil fertility and soil structure to a certain extent, most of them are slow to take effect. For the soil that has been severely compacted, the existing soil improvers cannot immediately improve the quality of crops. growth status
