Description

Magnetization slow release fertilizer of a kind of safe high yield and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, particularly a kind of magnetization slow release fertilizer and preparation method thereof of safe high yield.

Background technology

China is typical large agricultural country, and the many cultivated areas of the size of population are few, and chemical fertilizer plays very important effect in the production process of farm crop.Showing according to the study, can there is various physicochemical change in the nutrients such as the nitrogen be manured into soil, phosphorus, potassium, and wherein nitrogen can pass through the losses such as volatilization, leaching, denitrification, and phosphorus element is easy to by the Al in soil ³⁺, Fe ³⁺and Ca ²⁺, Mg ²⁺fix etc. various ion, form stable throw out or formed to close with iron, aluminum oxide etc. and store state phosphorus and progressively lose its validity.These factors all can cause the utilization ratio of chemical fertilizer application to reduce.The use of chemical fertilizer also can bring the pollution of environment simultaneously, as the eutrophication etc. of Greenhouse effect, water body.Therefore optimize fertilizer structure, popularization slowly-releasing and release and release control fertilizer are the effective ways improving utilization rate of fertilizer.

Soil-crop system pollution of trace is an organic mineral complex system that contain the synthesis of various ion-transfer, water molecules migration, enzyme and microbial process, magnetic field is by producing soil and biomagnetism effect to the effect of metal magnetic in the electron transmission in system, dipole orientations, enzyme and microorganism etc., to the release of soil nutrient, the ability of soil water-reataining fertilizer-keeping, water supply fertilizer is increased equally.Therefore, use Magnitizing method to prepare fertilizer to be used in soil plantation aspect there are very large potentiality.

The present inventor has prepared a kind of novel magnetization slow release fertilizer for this reason, respectively magnetized solid is carried out to fertiliser granulates and coating liquid carries out liquid magnetized, magnetic carrier is mixed by certain proportion with nitrogen, phosphorus, potassium and trace element etc., can under identical chemical fertilizer drops into, increase crop yield and utilization rate of fertilizer, soil nutrient status improved and improves quality of agricultural product, increasing income increases in grain production, increasing farmers' income and promoting agricultural development has important meaning.

(4) step 2 gained fermented liquid is mixed with tapioca (flour), and be heated to 75-80 DEG C, keep 10-20 minute, in solution, add calcium acetate, sulfuric acid silicon and other leftover materials again after being cooled to room temperature, and be heated to 60-70 DEG C, chelating 20-40 minute, in chelating liquid, composite bacteria agent is added again after cooling, stir, gained solution is placed in magnetizer, magnetize 5 minutes under the field intensity of 400-500mT;

(5) adopt the mode of high-pressure fog to be uniformly coated on step 3 gained magnetized particles outside surface, weighing and bagging after oven drying at low temperature step 4 gained magnetization coating liquid, and the warehouse be placed in away from ferrous metal material is preserved.

Beneficial effect of the present invention:

Magnetized use can cause the part hydrogen bond fission between coating liquid water molecules, the oxygen level of coating liquid is increased, thus causes the increase of ultra-oxygen anion free radical, makes coating liquid produce the insect killing effect of certain harmful bacteria, ensures the health of crop root.

After magnetization, in system, hydrone and water dimer molecule increase coating liquid freely, stripping nutrient is more easily entered in crop cell, to promote the metabolism of cell, strengthen cell viability, improve the photosynthesis of crop and the receptivity to nutritive substance, better complete slow-releasing and controlled-releasing action, promote crop growth.

Fertilizer of the present invention is rich in the macronutrients such as N P and K needed for plant growth, again without the limitation of common chemical fertilizer, wherein contained fermentation soil ulmin can make improvement to the physical properties of soil, the motion being conducive to crop root cell charged particle is used in the magnetization of fertiliser granulates, the liquid crystal structure of biomolecules can also be adjusted and change the permeability of film, promote metabolic process, accelerate Growth of Cells, ensureing that the prerequisite of soil and water resources safety is issued to the object of high crop yield.
