Multifunctional wormcast saline and alkaline land soil conditioner and preparation method thereof

Abstract

Provided are a multifunctional wormcast saline and alkaline land soil conditioner and a preparation method thereof. The multifunctional wormcast saline and alkaline land soil conditioner is prepared from, by mass, 50%-60% of wormcast, 20%-25% of furfural residues and 20%-25% of ardealite. The preparation method comprises the steps that straw is crushed into particles; the straw and sludge are mixed and stirred to be uniform, earthworm feed is obtained, earthworms are fed, and after the sludge in the earthworm feed has no odor or peculiar smell and becomes floppy crineous, the good sludge wormcast is generated at this moment; after the earthworms and the wormcast are separated, the wormcast is aired, the moisture content in the wormcast is made to be smaller than or equal to 30%, the wormcast, the furfural residues and the ardealite are stirred to be uniform, and the saline and alkaline land soil conditioner is obtained. The multifunctional wormcast saline and alkaline land soil conditioner has the advantages that the multifunctional wormcast saline and alkaline land soil conditioner has a good improvement effect on the severe physical and chemical properties and soil structure of saline-alkali soil, the harmful salt and alkalization degree of the soil are reduced, the porosity of the soil is improved, the saline-alkali soil is improved, the yield of crops is increased, and saline-alkali wasteland can gradually become farmland.

Description

technical field [0001] The invention relates to a saline-alkali soil improver and a preparation method thereof, in particular to a multifunctional vermicompost saline-alkali soil improver and a preparation method thereof. Background technique [0002] Saline-alkali soil is a kind of soil formed by salinization or alkalization. The surface soil of saline-alkali soil is mostly dry and white, and even forms salt crust, hardened and cracked, with high mineralization and strong corrosion, which can damage plant cell tissue and hinder plant growth. High salinity soil can even directly rot the root system of the plant and cause the plant to die. [0003] In view of the current situation that my country's per capita arable land is scarce, saline-alkali soil improvement technology can increase the area of ​​arable land that is the basic material for human survival, which has far-reaching significance for farming. [0004] At present, the treatment of saline-alkali land generally ado...

Problems solved by technology

[0004] At present, the treatment of saline-alkali land generally adopts acid neutralization method and water irrigation method. The acid neutralization method is to sprinkle acid liquid such as sulfuric acid on the saline-alkali land to make the pH value of the soil tend to be neutral, but it will cause further compaction of the soil; Water irrigation requires large amounts of fresh water to flush the soil from salt and alkali, but there is not enough water in many places
