The invention belongs to technical field of fertilizers, and in particular to a kind of natural composite fertilizer and preparation method thereof, the raw material group of the composite fertilizer becomes：Stalk, biogas residue, sodium alginate powder, buckwheat starch, attapulgite clay, modified meerschaum, hyacinth fermentation object, water.The effects that by adding the natural constituents such as modified meerschaum, biogas residue, attapulgite clay and hyacinth fermentation object, nutritional need and water conservation, fertilizer conservation, sustained release, improvement soil, bioactivation and the biological control of crops can be met comprehensively；Soil improvement and nutrition supply can be done, the yield and quality of crop is effectively improved, is a kind of environmentally protective efficient natural composite fertilizer.
Description
Technical field
The present invention relates to a kind of technical field of fertilizers, more particularly, to a kind of natural composite fertilizer and preparation method thereof.
Background technology
Compound fertilizer refers to the chemical fertilizer containing two or more nutrient, and composite fertilizer has nutrient content high, secondary
The advantages that ingredient is few and physical behavior is good improves utilization rate of fertilizer, the stable high yield of crop is promoted to have ten for balance fertilizing
Divide important role.But there are also disadvantages for it, for example its nutrients ratio is always fixed, and different soils, Different Crop
Required nutrient type, quantity and ratio is various；And people and largely make for the increasing both production and income of crop at present
With composite fertilizer, not only the quality of crop is had a huge impact, the quality of environment is also seriously affected, causes under product qualities
It drops or even harmful, soil block cures the problems such as serious.
Sepiolite is a kind of with the viscous of interlamination region ion-exchange performance, strong absorption property and strong dispersion performance (agglomeration resistance)
Native mineral, while a kind of clay mineral containing nutrient needed for crop again.The numerous characteristics of sepiolite can be agricultural production used in,
Main application has four：First, its mineral structure determines that its porosity is very high, the specific surface area of hole reaches 800~900m2/ g,
Therefore its strong adsorption, shelter have first of mineral, for the moisture content that it is adsorbed up to the 200~250% of own wt, it can fixing soil
Available nutrient, so that fast potassium is become " slow potassium ", alkali-hydrolyzable nitrogen becomes " late effect state nitrogen ", they under certain condition, by planting
Object needs rule to release again.Therefore it is chemical fertilizer, especially the nitrogen sustained release agent of nitrogenous fertilizer；Second is that its absorption other materials is
Make under the state that is impregnated with, it may have the mechanics resistance not being disintegrated, therefore its dispersion performance is good, can be used for preventing chemical fertilizer, the pesticide moisture absorption
And the dispersant to lump, it is allowed to keep dispersity without losing its effect for a long time；It is formed not third, it, is easy to dismiss in the solution
Rule network of fibers, including the solution medium and show as the suspension that very strong rheological characteristic makes stable, can be used as
The suspending agent of breeding；Fourth, it is a kind of clay mineral, clay can be increased by being added in the soil of grittiness weight, its hole is sent out very much
It educates, its drain and gas permeability can be improved in the soil for being added to viscosity weight.Therefore sepiolite is a kind of excellent soil conditioner,
It is added in composite fertilizer, can effectively solve the deficiency that conventional composite fertilizer brings environment and product.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of natural composite fertilizers and preparation method thereof, are modified by adding
The natural constituents such as sepiolite, biogas residue, attapulgite clay and hyacinth fermentation object can meet the nutrition need of crops comprehensively
The effects that wanting, and having water conservation, fertilizer conservation, sustained release, improvement soil, bioactivation and biological control concurrently；Soil improvement and nutrition can be done
Supply, effectively improves the yield and quality of crop, is a kind of environmentally protective efficient natural composite fertilizer.
