Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of composite fertilizer for being used to adjust soil function, and further relate to
The preparation method of the composite fertilizer.
Background technology
Water is Source of life, and soil is fundamental to the building of the country, and soil is that human society is rely and existed and the basic premise of development, is most
Important basic resource.One layer loose material of the soil as earth surface, it has many important functions：First, it is native
Earth is the important supply source of nutriment necessary to terrestrial life, has the function that nutrition library；Secondly, there is biologic strut
Effect, including the mechanical support to green plants, while it is additionally included in that species in soil is various and the biological group of enormous amount,
And support the life of terrestrial life and breed；Again, soil can play regulatory role to water body and solute flowing, so as to play rain
The function of water self-restraint；Again, soil can be converted and circulated to nutrient, so as to realize following between nutrient and biology
Ring and turnover, to keep living and multiplying for biological life cycle；Again secondary, soil also has stable and buffering environmental change work
With it is included to the buffering of ambient temperature, humidity, acid-base property and oxidation-reduction quality change and to organic and inorganic pollution
Filtering, buffering, degraded, fixation and removing toxic substances；Finally, soil can also keep bioactivity, diversity and productivity.
However, the increasing both production and income for improving agricultural economy crop in China's agricultural production all the time be unable to do without chemical fertilizer
Administration, but due to it is excessive or it is irrational use chemical fertilizer, use no or little organic fertilizer, the soil in China has occurred
The problem of various, such as hardened, nutrient imbalance, acidifying salination, soil texture variation, bio-diversity decline, soil
Pollution etc., so as to cause the performance of soil function to receive serious obstruction, many unfavorable factors are brought to agricultural production, such as beneficial
The missing of microorganism has interrupted earthworm food chain, so that earthworm this " loosen the soil expert " is from soil, and soil-borne disease
Killer i.e. beneficial microbe is lacked and rampant, so as to cause soil hardening, transparency and the ability of regulation and control to water are reduced, made
Thing root system branch measures and length substantially weakens, and the waterlogging-resistant ability of drought resisting declines.In addition, bio-diversity declines, beneficial microbe subtracts
Few, soil disease is rampant and propagated wide, and serious even resulting in can not plant crops on soil, as being mandarin orange before Guangdong Province
Tangerine plantation is big to be saved, and yet with the outburst of yellow twig, causes large area soil can not plant citrus again.These problems force research
Person constantly looks for and explored the method that can recover soil.
The A of CN 102795944 disclose a kind of soil improvement type bio-feritlizer and preparation method thereof, the bio-feritlizer by
Following raw material is mixed to prepare, and is parts by weight：Turf 200-400 parts, organic fertilizer 200-400 parts, inorganic fertilizer 100-400
Part, porous mineral 50-200 parts, micro- 10-30 parts, clay 50-80 parts, complex micro organism fungicide 10-20 parts.Due to
This application teaching bio-feritlizer be complex micro organism fungicide is directly mixed with other fertilizer obtained by, complex micro organism fungicide
Survival rate be difficult control.
Under the so severe situation of soil ecology, soil and plant research person suggest, microbial bacteria is applied into soil
Agent so as to improve ecological environment of soil, and improves crop yield and quality with improved soil character.Microorganism can dissolve soil
Immobilized mineral element in earth, increases the validity of nutrient, the pollutant in soil of degrading, and solves the danger of removing heavy metals and agricultural chemicals
Evil, some microorganisms can also secreting hormone class material, stimulate and adjust the growth of crop, some microorganisms can also produce volatility
Or the non-volatile material for suppressing growth of pathogenic bacteria, the growth or metabolism of pathogen can be limited, improves plant resistance to environment stress, has and protects
Shield and treatment double effects, can effectively prevent and treat soil-borne disease.Therefore, from the perspective of the ecological agriculture, microorganism is in agricultural
Aspect has broad application prospects.
In existing microbial manure preparation technology, microbial bacterial agent, high-temperature process are mainly added in granulation process
A large amount of microorganisms can be caused dead, and after applying, the microbial inoculum effectiveness time is short, repeated and stability is poor.Further, since microorganism
Microorganism in fertilizer directly can not contact with chemical fertilizer, therefore microbial manure is low, active there is Microbial survival rate
The problems such as poor, so as to cause the improvement of soil function not fully up to expectations, so need to develop a kind of Microbial survival rate height
And the simple fertilizers of preparation technology, to improve the present situation that current soil function constantly deteriorates, so as to promote soil function
Recover.
The content of the invention
In order to solve the above problems, inventor carries out research and analysis repeatedly to soil constituent, finds ferment
It is coated with after bacterium and water-soluble organic matter mixing in the surface for the fertiliser granulates for having wrapped up separation layer, avoids ferment bacterium with changing
Fertilizer is learned directly to contact, so that the hypersaline environment of chemical fertilizer does not interfere with the survival rate of ferment bacterium, and energy when being applied to soil
Enough increase living bacteria count in soil, increase soil fertility, improve soil texture, and microorganism and fertilizer can be given full play to simultaneously
Mating reaction between material, realize crop yield synergy.
