Vegetable field soil improving agent and its preparation method

Abstract

The invention relates to a vegetable fields soil amendment and a preparation method thereof, pertaining to the technical field of soil amendment. The vegetable field soil amendment comprises the materials: cattle manure, wheat bran, lignite, calcium nitrate, magnesium sulfate, borax, zinc sulfate, ferrous sulfate and water. According to weight proportion, the materials are mixed together and composted to fully ferment. The fermentation product is added with bacillus subtilis agent to make the final product of the soil amendment. The soil amendment of the invention contains rich organic matter, mineral and bacillus subtilis. The base fertilizer of 1000-2000Kg is applied in every 667 m2 of vegetable field, and can effectively improve soil properties of vegetable field, enhance soil power, increase vegetable yield and benefit. The invention has clear purpose and no pollution to environment.

Description

A vegetable field soil improver and preparation method thereof technical field The invention relates to the technical field of soil improvement, in particular to a vegetable field soil improver and a preparation method thereof. Background technique A good soil environment is the basis for high-yield, high-quality and efficient cultivation of vegetables. Vegetables grow fast, have a high multiple cropping index, and have weak disease resistance. The soil is required to have a good aggregate structure, a deep and loose tillage layer, appropriate porosity, high organic matter content, complete and sufficient effective nutrients, and a reasonable microbial flora structure. However, in recent years, the sown area of ​​vegetables has expanded rapidly, and a large number of unripe farmlands have become vegetable fields. In addition, unreasonable cultivation systems and field management measures in the later stage, such as continuous cropping, large-scale application of chemical ...

Problems solved by technology

However, in recent years, the sown area of ​​vegetables has expanded rapidly, and a large number of unripe farmlands have become vegetable fields, coupled with unreasonable cultivation systems and field management measures in the later period, such as continuous cropping, large-scale application of chemical fertilizers, and flood irrigation, etc., resulting in deterioration of the soil ecological environment of vegetable fields. The specific manifestations are: damage to the soil aggregate structure, easy compaction, and reduced permeability; organic matter content decreased, mineral nutrition unbalanced (overload accumulation of nitrogen and phosphorus and lack of trace elements such as calcium, zinc, and boron); accumulation of pathogenic microorganisms, etc. ( "Shanghai Vegetables", No. 6, 2006; "Journal of Plant Nutrition and Fertilizer", No. 1, 2003)

The deterioration of the soil ecological environment of the vegetable field directly leads to the poor growth and development of vegetable plants, and the decline in yield and quality
