Method for preventing and controlling salinization of planting soil in sunlight greenhouse

Abstract

A method for preventing and controlling salinization of planting soil in a sunlight greenhouse mainly comprises the steps of harvesting, ditching, film covering, filling, bacterium mixing, watering, ridging, fermentation, turning, material spraying, tillage and the like. The planting soil is wide in raw material source, low in cost, simple in process and environmentally friendly; the soil is good in air permeability and water permeability after the planting soil is used, and the good water retention and moisture preservation capacity is achieved; the planting soil has the effects of organic fertilizer and salinization retarding and has rich natural organic nutritional ingredients and a large amount of probiotics; the planting soil can break soil hardening, effectively regulate balance of microorganisms in soil, eliminate the phenomena of soil salinization and the like caused by dependence on abuse of chemical fertilizers all year round, enhance soil water and fertilizer seepage force, improve crop stress resistance and yield, and improve the yield of crops; therefore, the planting soil is an excellent saline-alkali modifier for the soil in the planting area.

Description

technical field [0001] The invention relates to the technical field of solving soil salinization, in particular to a method for preventing and controlling soil salinization in a solar greenhouse. Background technique [0002] Soil is the foundation of crop growth, maintaining the composition, structure and function of soil is the guarantee for the sustainable development of crop production. In recent years, with the rapid development of protected horticulture in northern my country, it has become very common to use solar greenhouses to grow crops. With the extension of cultivation time, due to the unreasonable management and utilization of soil, fertilizer and water, the soil environment quality in solar greenhouses is declining day by day, especially The pollution of soil pesticides, chemical fertilizers and heavy metal ions directly affects the yield and quality of crops, which has attracted great attention from the society and the public all over the world. Due to poor so...

Problems solved by technology

There are a lot of modifiers in the prior art, but most of them have insufficient improvement effects, long improvement cycle, temporary solution but not the root cause, small treatment area, and not suitable for widespread use, which limits the popularization and use of modifiers.

[0005] In addition, the improvement of salinized soil is also commonly used to wash salt with water, deep plowing foreign soil, physical and chemical methods, and plant improvement methods in agriculture. These methods can improve the physical and chemical properties of soil to a certain extent, but the operation High cost and prone to secondary pollution

[0006] At present, organic fertilizers prepared from animal and plant residues as organic sources are relatively new types of improved products. They have good application prospects in the fields of improving soil environment and utilizing salinized land. They not only have low cost, but also have the advantages of no secondary pollution. , has been recognized by many experts and scholars, but in the application of granular organic fertilizers to improve salinized land, there are still disadvantages such as slow effect and high improvement cost, and large-scale promotion and application have not yet been realized.
