Saline-alkali soil conditioner and preparation method thereof

Abstract

The invention discloses a saline-alkali soil conditioner which is prepared from the following components in parts by weight: 30-70 parts of enzyme preparation filter dregs, 10-60 parts of bone meal and 1-5 parts of a microbial inoculum, wherein the microbial inoculum is one or a combination of more than one of bacillus subtilis powder, bacillus mucilaginosus powder and bacillus megatherium powder. According to the saline-alkali soil conditioner disclosed by the invention, the enzyme preparation filter dregs are used for absorbing microbial preparations and are compounded of the bone meal which is rich in biological phosphorus and calcium. The enzyme preparation filter dregs have a relatively good inhibiting effect on pathogenic bacteria of crops, can be used for effectively preventing soil-borne diseases and meanwhile, are capable of promoting proliferation of beneficial bacteria such as nitrogen-fixing bacteria, cellulose decomposing bacteria, lactic acid bacteria and actinomycetes and inhibiting growth of harmful bacteria such as mould and filamentous bacteria. The bone meal is used for adjusting alkaline ions in soil and the micro-ecological environment of soil is improved by using mixed microbial preparations such as phosphorus and potassium solubilizing preparations and bacillus subtilis. By using industrial and agricultural wastes, the production cost is lowered and the product quality is improved. The saline-alkali soil conditioner has multiple functions and remarkable effect.

Description

technical field [0001] The invention relates to a soil conditioner and a preparation method thereof, in particular to a saline-alkaline soil conditioner and a preparation method thereof. Background technique [0002] The use of a large number of chemical fertilizers and pesticides, on the one hand, solves the problem of food quantity and increases economic income; on the other hand, it brings about more serious soil acidification and salinization. , nitrite, heavy metals and other harmful substances residues exceed the standard, soil micro-ecological environment is destroyed, cultivated land degradation, soil secondary salinization and other problems, to a large extent threaten food security and sustainable development of agriculture, directly or indirectly Harm the living environment and health of human beings. [0003] my country is a country where saline soil is widely distributed, and the area of ​​saline soil is about 1.0×10 8 Hectares, of which modern saline soil acc...

Problems solved by technology

[0004] The salt content in saline soil exceeds 0.3%, which will easily lead to soil compaction and decline in fertility, which is not conducive to the absorption of nutrients by crops and hinders the growth of crops
