Problems solved by technology

[0010] Although existing soil improvers can improve soil to a certain extent, there are still many defects. On the one hand, existing soil improvers have a single active ingredient, and excessive emphasis is placed on improving soil fertilizer efficiency or soil microbial activity, while Ignoring the improvement of soil water and fertilizer retention capacity and the role of inhibiting the activity of heavy metals and harmful substances
The effect is single, unstable, and lacks comprehensive regulation of multifunctional effects. Long-term use has large side effects, and it is easy to cause soil compaction, which is not conducive to the development and growth of crop root systems; suitable for wide application

Abstract

The invention relates to the technical field of soil environment conditioning and improvement, in particular to an organic active soil agent and a preparation method thereof. The organic active soil agent includes active humic acid 20-30%; magnesium sulfate 5-15%; surfactant 0.3-0.6%; modified bentonite or modified kaolin: the balance. The organic active soil agent prepared by the invention has the characteristics of convenient preparation, excellent water absorption and water retention performance, improvement and restoration of soil environment, improvement of ion adsorption and exchange capacity, improvement of fertilizer utilization rate, increase of plant yield, improvement of plant quality and the like. Used in soil, it can increase the content of soil organic matter and nutrients, promote the formation of soil aggregates, improve soil physical and chemical properties, improve soil structure, improve soil air permeability and water permeability, and improve soil adsorption, water retention, and fertilizer retention. Inhibit the activity of heavy metals and harmful substances. It can play a very good role in improving barren land, and the effect of long-term use is better.

Description

technical field [0001] The invention relates to the technical field of soil environment improvement, in particular to an organic active soil agent and a preparation method thereof. Background technique [0002] Soil is one of the main natural resources that humans rely on for survival, and it is also an important part of the human ecological environment. Human production activities are carried out on the soil, and the required agricultural products are also produced from the soil. The soil is largely It restricts the growth and development of plants and the effect of agricultural production measures. Therefore, soil is the foundation of agriculture and the pillar of economic and social development. It is an indispensable natural resource for human beings and is inseparable from human beings. [0003] However, with the improvement of socio-economic conditions and medical level, the population continues to increase, causing enormous pressure on food production. At the same ti...
