A kind of environment-friendly soil conditioner and preparation method thereof

Abstract

The invention discloses an environment-friendly soil conditioner and a preparation method thereof. The environment-friendly soil conditioner is prepared from the following raw materials: 1-5 parts of kaolinite, 1-5 parts of vermiculite, 1-5 parts of bentonite, 1-5 parts of zeolite, 0.5-1 part of hydromica, 10-20 parts of urban domestic sludge and 1000-2000 parts of effluent of urban domestic sludge treatment plant. The preparation method comprises the following steps: uniformly mixing the kaolinite, vermiculite, bentonite, zeolite and hydromica, putting the mixture into a permeable container made of a metal filtering net, soaking in the effluent of urban domestic sludge treatment plant for 7 days, taking out and airing the mixture; and then mixing with the urban domestic sludge, thereby obtaining the product. The soil conditioner can be used for improving the physical and chemical properties of soil, providing nutrient elements needed by plant growth, promoting plant growth, improving the plant biomass and enhancing the stress resistance of plants. Meanwhile, the soil conditioner can be used for effectively reducing plant transpiration and improving the photosynthesis of plants and is suitable for afforestation in arid regions, and the survival rate and preserving rate of forest plantation can be improved.

Description

technical field [0001] The invention relates to an ecological (agriculture and forestry) technology, in particular to an environment-friendly soil conditioner and a preparation method thereof. Background technique [0002] Land degradation has been a problem since the beginning of human settlement for agriculture. Especially in recent decades, with the rapid growth of my country's population, the area of ​​cultivated land has been decreasing day by day. Excessive reclamation and unreasonable human use have accelerated the process of land degradation, resulting in partial or complete loss of land productivity, which has greatly affected agriculture and forestry. sustainable development of the industry. After more than 100 years of research and application practice, there are more and more types of soil improvers, ranging from natural structure improvers, artificially synthesized improvers to later biological improvers, etc., which can effectively improve the physical and chem...

Problems solved by technology

[0003] In the prior art, most soil improvers still have more or less defects, excessive use leads to increased costs, incomplete improvement effects, or negative impacts to varying degrees, etc.
