Abstract

The invention belongs to the technical field of soil conditioning and improvement, and relates to a method using peat soil mixture ultrafine powder to repair and improve acidified hardened soil, saline-alkali soil, sandy land, stony land, and the like. The prepared ultrafine powder with a size of 3000 meshes or more has the characteristics of rapid differentiation, high solubility, strong activity, good bio-compatibility, and many elements. During the application process, the ultrafine powder has the advantages of simple operation, little using amount, low cost, and prominent effect, and thus has a good prospect in soil improvement.

Description

A kind of micro mist soil conditioner prepare method

Technical field

The invention belongs to technical field of land improvement, be specifically related to a kind of peat soil mixture ultrafine powder and prepare method for soil improvement.

Background technology

At present, main prior art brown coal, peat soil, the peat composed of rotten mosses etc. being used for soil improvement humic acids is wherein carried out chemical extraction, preparation humate and humic acid complex fertilizer.These method ubiquity resource utilizations are low, and production process has pollution.And existing processing technology, method and apparatus, generally brown coal can only be worked into 200 object particles, for soil improvement, usage quantity is large, and limited efficiency, added value of product is low, and market application surface is narrow.

Peat soil is plant materials corruption thing, and carbonation rate is low, and main component is organism, is present in occurring in nature existing more than thousand, has formed metastable internal structure.The present invention utilizes multistage controlled change rail micro ball-mill, by peat soil after cryodrying pre-treatment, be worked into micron order or thinner, make it have extremely strong activity, keep the multiple polymer functional group in its original organic matter active, can produce actively useful effect fast to the crumb structure, material migration, moisture retention etc. of soil, and trace element can be supplemented fast, the usefulness being conducive to soil microorganisms growth and the soil organism plays.

By widely applying experiment to find, ultra-fine peat soil mixture, after entering soil, differentiation is fast, and nutrient substance is complete, and chelating ability is strong, and consumption is few, and effect is high.Use procedure is without any secondary pollution, and resource utilization is high, successful, soil remediation instant effect, builds tool be of great significance for the current soil ecology reparation of China.

Summary of the invention

The feature of this peat soil micro mist soil conditioner, comprises following integral part:

1, containing the natural peat soil of organic more than 50%, the micro mist that particle diameter is less than 5 microns, is applied to soil activation improvement.

2, the natural peat soil containing organic more than 50% and the micro mist of solid alkali hybrid process to particle diameter less than 5 microns, be applied to soil acidity or alkalinity and regulate.

3, mix containing the natural peat soil of organic more than 50% micro mist being machined into particle diameter less than 5 microns with mineral substance, be applied to soil nutrient element and supplement.

4, be 5-15% containing the natural peat soil water content of organic more than 50%.

5, peat soil micro mist soil conditioner organic content is greater than 55%.

The essential characteristic of the technology of the present invention is:

One, the peat soil that occurring in nature is natural, through rotary-cut, is crushed to below particle diameter 1mm, then through multistage controlled change rail ball mill processing, use aperture 5um screen, powder delivery median size is greater than 3000 orders, gives full play to effect of organic polymer functional group;

Two, the acidifying existed according to soil is hardened, and grinds to form mixture micro mist, adjustable soil acidity or alkalinity and sedimentation after adding solid alkali mixing;

Three, destroyed soil, as there is the disappearance of nutritive element, grinds to form mixture micro mist energy Quick uniform after adding the mixing of corresponding mineral substance and is distributed in soil;

Four, peat soil micro mist can directly be incorporated in soil, also water soluble pouring, simple to operate;

Five, peat soil micro mist soil conditioner organic content is greater than 55%.

Example one

NaOH, 5%KOH mixture that peat soil containing organic 60% adds 3% is worked into particle diameter less than 5 microns, more than 3000 orders accounts for 80%, pH value 8.5; Management goal be severe acidifying harden ground 1000 square meters, pH value 5.3.Get 30kg peat soil plant remains mixture ultrafine powder, pour in the pond of 5 cubic metres of filled with water, solubleness is greater than 90%, pH value is 8.5, after stirring, is evenly poured onto soil surface, loosing soil after half an hour, from ground, down the 35cm earth 1kg that fetches earth adds water 50kg, and chemical examination P in soil H value is 6.5, and soil conditions obviously improves.

Example two

The KOH mixture that peat soil containing organic 65% adds 3% is worked into particle diameter less than 5 microns, pH value 7.2; Management goal is heavy salinized 30 mu, ground, saltiness 9.4%, pH value 8.6.Use 10 tons of water carrying capacity water barrows, add peat soil mixture ultrafine powder 50kg at every turn, share 200 tons, water, ultrafine powder 1 ton.After 24 hours, get 30cm soil and survey pH value 7.5.Maize planting 20 mu, seedling rate is greater than 81%, surviving rate 95%, 10 mu of other crops, and surviving rate is greater than 70%, surviving rate 93%.After three months, soil organic matter content improves 17.3 times.

Example three

Management goal, desertify 20 mu, ground, and desertification thickness is greater than 30cm, and organic content is lower than 5%.Peat soil mixture ultrafine powder consumption 600Kg, usage is the same, Zhong Jie farm, Cangzhou, plantation celery 10 mu, output 21823 jin, 10 mu, romaine lettuce, output 31252 jin.After three months, soil organic matter content 17%.

Example four

Lava basin, Yunnan, on rock, soil mean thickness is less than 8.2cm, and soil organic matter content is lower than 10%.The KOH mixture using the peat soil containing organic 75% to add 3% is worked into particle diameter less than 5 microns, more than 3000 orders accounts for 70%, pH value 7.2; Administer 10 mu, soil, plantation radish, each 5 mu of pumpkin, radish yield 6350 jin, pumpkin output 12665 jin.After three months, soil organic matter content is greater than 15%, and average thickness of soil is greater than 11cm.

Claims

1. organic content is greater than the natural peat soil of 60%, pre-treatment is to water content 5%-15%, below particle diameter 1mm, the mineral substance of the alkali and 0.1%-5% that add 5%-10% is ground to the ultrafine powder of particle diameter less than 5 microns under normal temperature and pressure, admixes or dissolves in 100-300 water doubly to water at soil surface and spill with soil.

2. according to claim 1, alkali and mineral can be used alone with peat soil, or compound use.

3. according to claim 1, the method be applicable to acidity harden ground, saltings, desertification ground, stony desertification ground.
