Problems solved by technology

[0005] However, cellulose in wetland plants is usually connected with hemicellulose and lignin, and its heterogeneous groups are various hexose, pentose, and uronic acid polymers, which are difficult to be decomposed by microorganisms; at the same time, in The cellulose in the cell wall of wetland plants is also protected by lignin, making it difficult for many microorganisms to decompose it

Abstract

The invention discloses a coastal beach saline-alkali soil conditioner and a preparation process thereof. The preparation process of the soil conditioner mainly comprises the following steps: S1, preparing the complex microbial inoculant; s2, carrying out anaerobic fermentation; s3, preparing a soil conditioner. The invention aims at key elements in coastal tidal flat wetland soil improvement and restoration, wherein the ecological effect of wetland plant litter return is simulated, wetland plant degradation compound bacteria are used for accelerating the degradation process of wetland plants, and the prepared soil conditioner is rich in humus, humic acid and inorganic salt and high in organic carbon content and has the good application prospect. The method can effectively solve the problems of poor coastal mud flat soil, high salt content, single biodiversity, fragile ecosystem and the like, is simple in process flow, low-carbon and environment-friendly, and has very high practical value and economic value.

Description

technical field [0001] The invention relates to the technical field of ecological restoration of saline-alkali land, in particular to a soil conditioner for saline-alkali land in coastal beaches and a preparation method thereof. Background technique [0002] Coastal beach salinization will lead to sticky soil structure, poor air permeability, high soil bulk density, slow rise in soil temperature, poor activity of aerobic microorganisms in the soil, slow nutrient release, low soil permeability coefficient, strong capillary action, and intensified salinization, etc. question. In addition, the salinization of coastal beaches can also cause physiological drought of plants, damage plant tissues, affect normal plant nutrition and close the stomata of plants. Ultimately, it leads to serious problems such as poor soil, high salinity, single biodiversity, and fragile ecosystem. [0003] Studies have found that organic carbon in soil is the core factor affecting soil conditions, and...
