Special conditioner for facilities soil secondary salinization and preparation method thereof

Abstract

The invention discloses a special conditioner for facilities soil secondary salinization and a preparation method thereof. The conditioner comprises 40 to 60 weight parts of traditional Chinese medicine residue, 20 to 30 weight parts of livestock manures, 10 to 20 weight parts of furnace slag, 0.2 to 0.5 weight part of full nutrient elements, 0.01 to 0.05 weight part of composite fermentation bacterium agent and mycorrhizal fungus agent. The raw materials excluding the mycorrhizal fungus agent are added with water and uniformly mixed, and the mixture is piled and fully fermented. The mycorrhizal fungus agent in an amount which is 5 to 10 percent of the mass of the fermentation product is added into and uniformly mixed with the fermentation product, and the mixture is dried in the air naturally to form the conditioner. The conditioner can improve the organic matter content and aggregate structure of the soil, increase the permeability of the soil, and suppress the rise in salt content.Therefore, a solution to facilities soil secondary salinization is provided, the sustained development of facilities cultivation is ensured, the environmental pollution problem caused by waste traditional Chinese medicine residue is solved, and the pollution-control loads of enterprises are reduced.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to an agent for improving secondary salinization of facility soil caused by human effects and a preparation method thereof. Background technique [0002] With the development of protected cultivation, the utilization of protected soil has become an important part of my country's agricultural development. This production method of intensive use of land has not only enriched the food basket of our people, but also has become a pillar industry in many areas, greatly increasing the income of farmers. [0003] Facility cultivation is a land use method with strong human influence. It is characterized by the use of artificial measures to change the local ecological environment, making full use of light energy and heat energy, and creating an environment suitable for crop growth. Facility cultivation plays an important role in realizing the annual supply of vegetables and the bala...

AI Technical Summary

Problems solved by technology

Facility cultivation plays an important role in realizing the annual supply of vegetables and the balanced listing among varieties. However, due to its specific environmental conditions, cultivation methods, and partial and heavy application of chemical fertilizers, the soil quality deteriorates, and the problem of continuous cropping obstacles is becoming more and more serious. Sustainable development of vegetable production

In particular, the phenomenon of soil salt accumulation is obvious, and soil secondary salinization has become the main limiting factor for facility vegetable production.
