Abstract
The invention discloses a preparation method of a phosphate-coated fertilizer storage ceramisite, relating to the technical field of plant and vegetation fertilizer production. The preparation method comprises the step of coating a phosphorus material, a magnesium material, a calcium material and dry coal ash outside a ceramisite on which potassium phosphate is adsorbed. According to the invention, fertilizer is stored into the ceramisite by sufficiently utilizing a great number of communication holes on the surface of the ceramisite, then, the ceramisite is coated by using phosphate which is not dissolved into water, but is dissolved into acid, when acid rain exists, a ceramisite coating layer is slowly dissolved to release nutrient elements, the fertilizer inside the ceramisite is slowly dissolved out and is supplied to plants after the rainwater is infiltrated into the ceramisite, and part of rainwater is stored into the ceramisite and is released when being drought so as to provide a water source for the growth of the plants.
Description
Technical field
The present invention relates to the production technical field of plant, vegetation fertilizer.
Background technology
The afforestation vegetation of outlying mountain area or slope of highway, the artificially applying fertilizer maintenance difficulties of watering is large, how to make vegetation soil itself there is water storage and store up fertile performance, and can be in long-time lasting supply plant, significant to assurance plant-growth.Therefore how afforestation vegetation soil when forming design, makes the long-acting water storage storage of vegetation soil fertilizer is the performance of important consideration.
Zhou Songwei relates to a kind of soil greening and uses net dress tissue layer as long-term water conservation medium in patent CN101491174A, effectively increases the surviving rate of plant.
Because haydite is a kind of low density, high cylindrical compress strength, the hard porous material of shell, have water storage performance good, the excellent properties such as prevent soil erosion and prevent that earth from hardening.In vegetation soil, pre-buried haydite reaches a kind of usual way of the object Ye Shi vegetation local soil type one-tenth design of water storage, as laid haydite layer in the patent CN202374794U of Luo Weicong, Ou Yangwenwen etc. in vegetation soil, both reached the object of water storage, increased again ventilation property and the hydrophobicity of soil, prevented that effectively in advance seedling root from rotting.But because the existing haydite water storage time is shorter, can't meet the requirement of the afforestation vegetation of outlying mountain area or slope of highway.
And conventional chemical fertilizer mostly is readily avaiable fertilizer, will be ineffective in a middle or short term at soil, for a long time in the time for plant provides nutrition, and if chemical fertilizer sow excessively, can cause soil compaction, even cause plant death.
Summary of the invention
The object of the invention is to propose the preparation method that Phosphate coating long, slowly releasing nutrients of a kind of water conservation time stores up fertile haydite.
The present invention has haydite outer cladding phosphorus material, magnesian, calcareous material and the flyash dry powder of potassiumphosphate in absorption.
Concrete grammar comprises the following steps:
1) haydite is soaked in potassiumphosphate saturated aqueous solution and after at least 30 minutes, take out nature and dry, then the mixed solution forming with water and water reducer is sprayed onto the fertile haydite of the storage of drying surface, until store up fertile haydite moistened surface; If soak time is lower than 30min, haydite can not be soaked into completely, as long soaking time, affects preparation efficiency;
2) phosphorus material, magnesian, calcareous material and flyash dry powder blend is even, obtain mixed powder;
3) under agitation condition, mixed powder is sprinkled in the fertile haydite of storage of moistened surface, make to store up fertile haydite and be wrapped by completely;
4) the fertile haydite of the storage of coated mixed powder is dried under normal temperature environment.
The present invention makes full use of haydite surface a large amount of communicating apertures, chemical fertilizer is stored in haydite, again by haydite with water insoluble but be dissolved in sour Phosphate coating, when having acid rain to exist, except haydite coating layer is slowly dissolved and puts nutritive element, rainwater infiltrates after haydite, the slow stripping of chemical fertilizer of haydite inside, supply with plant, and part rainwater storage is in haydite, when drought, discharge, for plant-growth provides water source.
The present invention has following characteristics:
1. the fertile haydite of the prepared storage of the present invention, after being coated, having possessed long-term water storage and has stored up fertile function, and can slowly discharge, for plant-growth provides moisture and fertilizer.
2. the main cementing component of coating layer of the fertile haydite of the coated storage of the present invention is trimagnesium phosphate and calcium phosphate, trimagnesium phosphate and calcium phosphate are water insoluble, but be dissolved in acid, when having acid rain to exist, sulfate ion in acid rain, the slow dissolving phosphoric acid magnesium of nitrate ion and calcium phosphate, when providing nutritive element for plant, consumed the harmful ion in acid rain.
3. the present invention fails to stick to the material that forms coating layer on the fertile haydite of storage, and composition character is the same with coating layer, is all slow release fertilizer.
4. the present invention is encapsulated in chemical fertilizer in haydite, has avoided running off and the detrimentally affect to soil.
5. flyash belongs to industrial by-products, and using great quantities of powdered coal ash and lytag, belong to utilization of waste material, and flyash self contains a large amount of nutritive elements, be soil filled the source of manure.
6. preparation technology of the present invention is simple, and not perishable in air, is applicable to production department's large-scale production long-term preservation that condition is simple and crude.
In addition, in order to promote to be shaped, the present invention in described step 3), during stirring, can also water and the mixed solution of water reducer formation spray.
The mixed material feeding mass ratio of described phosphorus material, magnesian, calcareous material and flyash dry powder is 1 ︰ 0.2～0.7 ︰ 0.4～1.25 ︰ 1～3.Under this material compositing range, slow-release fertilizer formation reaction speed is moderate, and main raw material(s) utilization ratio is high.
Described mixed powder is 1 ︰ 0.17～0.33 with the mixing quality ratio of the fertile haydite of storage of moistened surface.It is completely coated that this proportional range can be fitted haydite, and powder has a small surplus.
The mixing quality ratio of described water and water reducer is 1 ︰ 0.0005～0.005.This proportional range can be easy to control powder humidity, is difficult for again making the excessive admixture of water reducer, causes waste.
