Description
Technical field
The invention belongs to soil remediation and improving technology field, and in particular to a kind of novel environment friendly soil conditioner and its system
Preparation Method and application.
Background technology
Soil is the basis of terrestrial ecosystems, and the basic bar such as necessary nutrition, air, moisture is provided for plant growth
Part, it is the basis of developing agricultural production.But the land quality in China allows of no optimist, the hardened, salination of acidifying, nutrient loss or
The problems such as unbalance, organic matter decline, heavy metal pollution, microbial diversity reduce is on the rise.Above-mentioned soil constraint factor
In the presence of causing cultivated-land to decline, crop yield is low and unstable, and serious threat sustainable development and the national food of agricultural
Safety.According to incompletely statistics, China arable land in the presence of 78.5% the various various forms of soil constraintses in farmland.How
Pass through the method elimination limitation obstacle of soil improvement, the microbial diversity for increasing soil, the basic topography in lifting arable land, improvement
Agricultural production conditions, it is a significant problem urgently to be resolved hurrily in current agricultural production.
It is one of repairing degenerated soil, the main counter-measure for lifting soil fertility using soil conditioner.Soil conditioner can
Effectively to improve soil physico-chemical property and trophic level, and there is good facilitation to edaphon, so that soil
It is more suitable for crop growth.According to the source of its nucleus, natural type, synthesis type, bion and compound can be classified as.
Natural type conditioner mainly uses natural minerals, inorganic or organic waste, naturally extracts high-molecular compound, be natural organic
Matter etc. is prepared for raw material.Using the intrinsic physics and chemistry attribute of conditioner composition, improve the physical arrangement and liquid manure characteristic of soil；
Synthesis type conditioner is to simulate natural material, the high molecular polymer synthesized by organic chemistry means, to improved soil；It is raw
Thing type is then to use the microorganism from branch mycorhiza for representative, using its vital movement or its accessory substance, the increase content of organic matter and
Mineral nutrient is activated, improves soil quality.Compound is to be compounded above-mentioned three kinds of different types of conditioners, takes long benefit
It is short, it is used in combination, reaches more excellent improved effect.Although the soil conditioner of above-mentioned several types obtains in agricultural production
Extensive use has been arrived, but has still suffered from that improved effect is not comprehensive, or the different degrees of negative issues such as secondary pollution, side effect be more.
A kind of combined soil formed with natural minerals loading multiple-microorganism microbial inoculum of Institute of Microorganism, Academia Sinica's invention is adjusted
Agent is managed, there is natural environmental-protective, synergy of improving the soil, easy to use, cost is cheap, is a kind of green soil conditioning skill
Art, meet ecological agriculture development trend.
The content of the invention
It is an object of the invention to provide a kind of composite environment-friendly soil conditioner and preparation method thereof, it is to pass through concave convex rod
Soil, humic acid and composite bacteria agent are formulated, and wherein attapulgite is a kind of magnesium alumino metasilicate containing Shuifu County with chain layer structure
Salt attapulgite mineral, there is higher porosity and specific surface area, can be as the excellent of microorganism after humic acid is modified
Carrier；Humic acid contains the functional groups such as a large amount of carboxyls, phenolic hydroxyl group, has loose porous structure and stronger viscosity, can promote
Enter Zinc fractions crumb structure, while displace the sodium ion in soil jointly with natural clay, so as to play a part of salt reduction,
And the carbanion in deep subsoil water body can be fixed, so as to have the function that to reduce soil pH value；Addition
Composite bacteria agent is nucleus, higher from colonazition in soil, can both effectively facilitate soil mineral and organic matter
Decompose, lift soil fertility, improve the nutrition condition of soil, and can effectively lifts the quantity of beneficial rhizosphere microorganisms flora, excellent
Change soil microenvironment.
