Soil conditioner for greenhouse continuous cropping obstacles and preparation method thereof

Abstract

The invention relates to a soil conditioner for greenhouse continuous cropping obstacles and a preparation method thereof. The soil conditioner is formed by uniformly mixing a base stock and an auxiliary material; the base stock is formed by mixing and fermenting peat soil, soybean meal slags, Chinese medicine residues, meshed grapes, meshed apples, meshed lemons, lactic acid bacteria, proteolyticenzyme, nitrogen-fixing bacteria, nodule bacteria, phosphate solubilizing bacteria, potassium bacteria, cellulose decomposition bacteria, antibiotics producing strains and water; the auxiliary material is formed by uniformly mixing wormcast, charcoal slags, medical stone powder and lime powder. The preparation method of the soil conditioner comprises: A, preparing the base stock; B, preparing theauxiliary material; C, preparing the soil conditioner. The soil conditioner disclosed by the invention is rich in nutrient substance, can effectively solve the problem of soil hardening, improves soil gas permeability, regulates soil acid-base balance, reinforces fertilizer-retaining and water-retaining capacity, promotes absorption of plants for nutrient substances, and effectively solves the greenhouse continuous cropping obstacles; the preparation method of the soil conditioner is simple and easy to operate, low in investment cost, suitable for large-area popularization and more sufficientand complete in fermentation and decomposition of raw materials.

Description

technical field [0001] The invention relates to the field of planting, in particular to a soil conditioner and a preparation method thereof. Background technique [0002] In recent years, many solar greenhouses have been built in various places for vegetable planting and production. After several years of continuous use of the greenhouses, there will be aggravated damage from diseases and insect pests, deterioration of soil chemical properties, and aggravated soil acidification. As the number of greenhouses increases continuously, the yield and quality of vegetables decrease, which seriously affects economic benefits, and some greenhouses even have to be abandoned because of this.

Problems solved by technology

[0002] In recent years, many solar greenhouses have been built in various places for vegetable planting and production. After several years of continuous use of the greenhouses, there will be aggravated damage from diseases and insect pests, deterioration of soil chemical properties, and aggravated soil acidification. increasing, the yield and quality of vegetables decrease, seriously affecting economic benefits, and some greenhouses even have to be abandoned because of this.

[0003] Continuous cropping obstacles mainly refer to the relatively single planting structure in vegetable greenhouses. At present, tomatoes, eggplants, peppers, cucumbers and other few kinds of vegetables are mainly planted. Long-term planting of a single variety will cause soil fertility imbalance and plant disease resistance. The phenomenon of production reduction

At the same time, in order to pursue high yields, most vegetable farmers use a large amount of chemical fertilizers with a single nutrient, which leads to changes in soil properties, causing soil compaction, salinization, and aggravation of diseases.

[0004] Although the existing soil conditioners have certain significance for solving soil compaction, alleviating soil saline-alkali hazards, adjusting soil acid-base balance, and enhancing soil fertility and water retention, crops cannot absorb organic matter and trace elements in the soil well. So that the soil conditioner can not play an immediate effect, continuous cropping obstacles can not be effectively resolved
