A kind of preparation technology of saline-alkali soil conditioner

Abstract

The invention discloses a preparation process of a saline-alkali soil improver, which comprises the following steps: using a straw pretreatment device to pretreat the straw, sterilizing the pretreated straw, and killing the sterilized and insecticided straw. Mix with soil structure improver and organic alkali-reducing raw materials, and perform composting treatment, and use the composting device to turn the composted materials. In the present invention, the straw pretreatment device can be used to finely crush the straw, thereby facilitating composting, improving the efficiency of composting, and accelerating the decomposition of the straw. The strength of the straw is reduced, and the degree of subsequent refinement is directly improved. The cam cutter head is a cam disc-shaped structure, which has higher strength, and the cutting depth gradually deepens. It can smoothly split the harder straw.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil improver preparation. Specifically, it is a preparation process of a saline-alkali soil conditioner. Background technique [0002] Saline-alkali land is a type of salt accumulation. The salt contained in the soil affects the normal growth of crops and will destroy the normal structure of the soil. The current improvement methods generally include water conservancy improvement, agricultural technology improvement, chemical improvement and biological improvement. , biological improvement generally uses methods such as returning straw to the field. When using straw, the degree of refinement of straw is not enough, which affects the post-treatment of straw, especially when dealing with hard straw. The existing processing equipment has certain shortcomings, and in During post-processing of straw, it is inconvenient to turn over. Contents of the invention [0003] Therefore, the technical...
