Preparation method of seaweed biological soil conditioner with saline and alkaline land improvement function

Abstract

The invention discloses a preparation method of a seaweed biological soil conditioner with a saline and alkaline land improvement function. The soil conditioner is prepared with a compound microbial fermentation technology from raw materials including Enteromorpha, kelp and oyster shell powder, has the functions of seaweed fertilizer, microbial fertilizer and organic fertilizer, contains rich seaweed functional active ingredients and large quantities of probiotics, can effectively regulate microbial balance of soil, decompose organic or inorganic constituents such as organic matters, mineral substances and the like in the soil, eliminate soil hardening, desertification, salinization and the like caused by abuse of chemical fertilizer all year round and improve the soil effectively, has the specific function of improving the stress resistance of crops, and improves the crop capacity; the soil conditioner can especially promote release of the organic matters in the soil, improves the physicochemical structure of salinity soil, improves the soil aggregate and permeability, improves the soil fertility, improves the grain yield increase capacity of a saline and alkaline land and is an excellent saline and alkaline land soil conditioner and a crop growth promoter.

Description

technical field [0001] The invention belongs to the technical field of fertilizer processing, and relates to soil conditioner technology, in particular to a preparation method of a seaweed biological soil conditioner with the effect of improving saline-alkali land. Background technique [0002] At present, soil salinization is very serious, which has a great impact on agriculture and is not conducive to planting. Due to the poor physical and chemical functions of salinized soil, the microbial activity in the soil is very low, and plants cannot grow normally, which has brought adverse effects on agricultural production. The area of ​​salinized soil in the world is about 8.97 million square kilometers, accounting for about 6.5% of the world's land area and 39% of the total area of ​​arid areas. The area of ​​salinized soil in my country is about 200,000 square kilometers, accounting for about 2.1% of the total land area. In my country's 100 million square kilometers of arabl...

Problems solved by technology

[0003] For the improvement of salinized soil, irrigation and salt washing, deep plowing of foreign soil, physical and chemical methods, and plant improvement methods in agriculture are commonly used. These can improve the physical and chemical properties of soil to a certain extent, but the operation cost is high and easy. produce secondary pollution

Seaweed fertilizers and microbial fertilizers are relatively new improved products at present. They have good application prospects in the fields of improving the soil environment and utilizing salinized land. They are not only low in cost, but also have no secondary pollution. They have been recognized by many experts and scholars. The improvement effect of seaweed functional substances and microorganisms; however, in the application of seaweed fertilizers and microbial fertilizers to improve salinized land, there are still disadvantages such as poor effect and high improvement cost, and large-scale promotion and application have not yet been realized
