Soil melioration matrix prepared from garden waste and preparation method of soil melioration matrix

Abstract

The invention discloses a soil melioration matrix prepared from garden waste and a preparation method of the soil melioration matrix. The soil melioration matrix comprises the following components in parts by weight: 0.05-0.08 part of garden waste subjected to fermentation treatment by a microorganism bacterium agent, 0.01-0.03 part of natural mineral and 0.005-0.01 part of polymaleic anhydride. According to the invention, the soil melioration matrix is added to saline soil, so that the physicochemical property of soil can be improved, the porosity is increased, the permeability is strengthened, the soil structure is improved, and the salt-obstruction and fertilizer conservation effects are remarkable.

Description

technical field [0001] The invention relates to a soil improvement matrix, in particular to a soil improvement matrix made of garden waste and a preparation method thereof. Background technique [0002] With the continuous deepening of economic development, ecological problems have become increasingly prominent, especially the problem of land salinization, and the problem of soil salinization in coastal areas has become more prominent. Coastal saline-alkali soil has the disadvantages of high salinity, low nutrient, large specific gravity and bulk density, small porosity and permeability coefficient, etc., which greatly restricts the ecological construction and agricultural production in coastal areas. Therefore, it is of great practical significance to find an economical and effective way to treat and utilize coastal saline-alkali soil in terms of ecology. In addition, with the rapid development of ecological cities, the urban green area has increased rapidly, and the amoun...

Problems solved by technology

[0004] Although the above-mentioned improvement measures can reduce the salt content of the soil, they still have their own shortcomings. The physical and engineering improvements are more destructive to the original soil structure, and the soil fertility after improvement is low; the amount of agricultural improvement projects is large, and the objective The cost of soil and transportation increases the cost; the mechanism of chemical improvement is complex and unstable, such as gypsum improvement commonly used in the prior art, but the main component of gypsum is CaSO 4 , is also a kind of salt, if too much soil salinity is applied, it will also increase; biological improvement needs a long period, lack of biodiversity, and the landscape is monotonous
