Abstract

The invention provides a soil amendment and a preparation method thereof. The method utilizes sludge to prepare the soil amendment, which has rich and comprehensive nutriments and high organic matter content. The used main raw materials are from waste reclamation and reuse, the production cost is very low, and the production process is simple, thus being conducive to large-scale popularization and application. The used raw materials do not contain any artificially synthesized chemical substance, and have no pollution to the soil environment. The soil nutritional status and soil structure can be significantly improved, crop production increase is promoted, and the ecological and economical benefits are significant.

Description

A kind of soil improvement agent and preparation method thereof

Technical field

The invention belongs to agromelioration technical field, be specifically related to a kind of soil improvement agent and preparation method thereof.

Background technology

China's agricultural development is experiencing one with the road of the modern agriculture science using chemical fertilizer, agricultural chemicals and hormone to be core in a large number, after the high strength development of many decades, and the positive all kinds of corrupt practices prevailing of chemical farming.The huge negative impact that abuse fertilizer and pesticide causes to farm crop, the problems such as soil compaction, organic matter decline, soil acidification aggravates, salinization of cultivated land is serious emerge in an endless stream in various places, and soil keeps healthy, extremely urgent.Along with a large amount of pollutant emissions in course of industrialization, and a large amount of uses of chemical fertilizer, agricultural chemicals in agricultural production process, soil is subject to pollution in various degree.Not only want to administer widespread pollution from the overuse of fertilizers and pesticides in rural area, eliminate soil compaction; And more to ensure the safety of agricultural products in China, for developing china formula Organic farming, produce health organic farm products and play vital effect.In the theory of soil health care, core solves soil aggregate problem and soil health problem.According to " the national Soil Pollution Investigation publication " issued a few days ago, the total exceeding standard rate of China's soil pollution reaches 16.1%, totally allows of no optimist, and some position exceeding standard rate of wherein ploughing is more up to 19.4%, arable soil environmental quality causes anxiety, and has also beaten alarm bell for China's soil pollution and food safety.Farmland Soil Pollution, not only causes a large amount of underproduction of agricultural-food or total crop failure, even produces serious harm to the crowd of long-term edible contaminated agricultural-food; The characteristic of flyash can promote the reunion of soil particle, increases soil granular quantity, improves water retention and biological activity, supplements the necessary trace element of soil, thus reaches the effect improved Soil structure, increase soil fertility.

Summary of the invention

In order to make up the deficiency of above technology, the invention provides a kind of soil improvement agent and preparation method thereof.A kind of method utilizing mud to prepare soil improvement agent, it is characterized in that, containing 10 parts-20 parts, mud, natural pond slag 20 parts ~ 30 parts, peanut dregs 10 parts-20 parts, crop material 10 parts-20 parts, 5 parts ~ 10 parts, sea-food shell, 10 parts ~ 20 parts, flyash, 5 parts ~ 10 parts, ground phosphate rock, complex micro organism fungicide 0.2 part ~ 0.5 part.

Preferred version of the present invention is, a kind of soil improvement agent and preparation method thereof, it is characterized in that 15 parts, mud, natural pond slag 25 parts, peanut dregs 15 parts, crop material 15 parts, sea-food shell, 7.6 parts, 14 parts, flyash, 8 parts, ground phosphate rock, complex micro organism fungicide 0.4 part.

The preparation method of soil improvement agent of the present invention comprises the following steps:

Step 1: by natural pond slag, sea-food shell, flyash, ground phosphate rock, pulverize or be ground to below 80 orders, pulverizes peanut dregs, crop material, and mixes to evenly by following weight part.Wherein, described mud is the mud that heavy metal content does not exceed standard, or after heavy metal harmless treatment, reach the mud of secondary standard, natural pile fermentation degraded;

Step 2: by above solid accumulation, long-pending heap mud is floating, insulation, prevents water loss and peculiar smell from shedding; Hide with black plastic cloth above, internal temperature remains on 50 DEG C ~ 65 DEG C, thus effectively kills worm's ovum and germ.Stack retting 15-20 days;

Step 3: by the mixture after fermentative degradation, natural air drying or less than 45 DEG C dryings, after water ratio <22%, i.e. obtained finished product.

Step 4: bag distribution packaging.

Soil improvement agent nutritive substance of the present invention is comprehensively abundant, and organic content is high; Main raw material(s) used is changing waste into resources recycling, and production cost is very low, and production technique is simple, is conducive to applying on a large scale; Raw materials is not containing the chemical substance of any synthetic, pollution-free to edatope; Can obviously improve soil nutrient status and Soil structure, promote crop yield, its Its Eco-economic Benefit is obvious.
