Preparation process of saline-alkali soil conditioner

Abstract

The invention discloses a preparation process of a saline-alkali soil conditioner. The process comprises the following steps: pretreating straws by using a straw pretreatment device, sterilizing and killing insects of the pretreated straws, mixing the sterilized and insecticidal straws with a soil structure conditioner and an organic alkali-reducing raw material, carrying out composting treatment and turning the compost materials by a turning device. By means of the straw pretreatment device, straw can be subjected to fine crushing treatment, so that composting is facilitated, the composting efficiency is improved, and decomposition of the straw can be accelerated; the straw is longitudinally split under the action of the longitudinal chopper set, so that the strength of the straw is reduced, and the follow-up refining degree is directly improved; and a cam cutterhead is of a cam disc-shaped structure, the strength of the cam cutterhead is higher, and the cutting depth is gradually and gently increased, so that harder straws can be smoothly split.

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...
