Abstract
The invention discloses an organosilicon fertilizer; the prepared organic farming fertilizer is composed of the following ingredients by weight percentage: 60-70 percent of oil shale powder, 10-15 percent of calcium superphosphate, 10-15 percent of potassium sulfate and 5-10 percent of magnesium sulfate; the sum of the raw materials is 100 percent; by adopting the organosilicon fertilizer, the using amount of the pesticide is reduced, the agricultural output is improved, the agricultural product quality is improved, hardening and pollution of chemical fertilizer and pesticide to the soil are eliminated, the plant growth is beneficial to environment, soil fertility of the soil is improved and the agricultural high yield and high quality are realized.
Description
Technical field: the present invention relates to a kind of fertilizer and preparation thereof, specifically utilize natural oil shale to be basic raw material, adopt modern biotechnology technology and scientific formula to be refined into a kind of organosilicon fertilizer and preparation method thereof.
Background technology: in recent years along with the development of agriculture production, the peasant utilizes chemical fertilizer to obtain the grain high yield, and the harm that brings of the disease and pest that utilizes highly toxic pesticide control farm crop, but, above-mentioned chemical fertilizer and highly toxic pesticide have also brought potential hazard also for agricultural, the development that spreads along with this harm has directly endangered human beings'health.As the agricultural-food (grain, fruit, vegetables) that use highly toxic pesticide to produce all can inevitably carry the pesticide residue material; The life-time service chemical fertilizer can cause soil compaction in the arable soil of rural area; destroyed soil aggregate; influenced the soil microorganisms eubiosis; make soil fertility fall sharply; bring the hidden danger of the underproduction for later agriculture production, also can cause the agricultural product quality quality of production seriously to descend, the national Ministry of Agriculture had recognized this point in these several years; require soil to use organic fertilizer to improve this state, preserve the ecological environment and human body health.
At present existing many fertiliser production producer is at the fertilizer of development of new, domestic employing resinous shale is made fertilizer also seldom by biological degradation, even the commercial product of minority is arranged, its output is few, can not satisfy the demands far away, can't meet the quality requirement, and promote the use of very difficult.Therefore developing new nuisanceless fertilizer also is the focus that the insider pays close attention to.
Summary of the invention: at the defective or the deficiency of above-mentioned prior art existence, the objective of the invention is to, a kind of organosilicon fertilizer and preparation method thereof is provided, this organosilicon fertilizer is a raw material with natural oil shale, utilize microbial strains to decompose the resinous shale raw material, add nitrogen, phosphorus, potassium element then, be refined into high reactivity with modern vanguard technology, the green organic manure multi-functional, nontoxic, nuisanceless, easy to use, that fertilizer efficiency period is long.
Realize above-mentioned purpose, the technical scheme that the present invention takes is:
A kind of organosilicon fertilizer, the material composition and the weight percent thereof that it is characterized in that this organic agricultural fertilizer of making are: the resinous shale powder raw material: 60%~70%, and calcium superphosphate: 10%~15%, vitriolate of tartar: 10%~15%, sal epsom: 5%~10%, the summation of above-mentioned raw materials is 100%;
The composition of described resinous shale powder raw material and weight percent thereof are: resinous shale: 70%, and straw powder 14%, medical stone powder 10%, wheat bran: 5%, yeast: 0.6%, urea: 0.4%, the summation of raw material is 100%;
The preparation method of above-mentioned organosilicon fertilizer is characterized in that, comprises the following steps:
Step 1 at first prepares the resinous shale powder raw material:
It is oven dry 24 hours under 100 ℃~150 ℃ the condition that resinous shale is placed on temperature, is crushed to 100~200 orders then, sieves, and obtains the resinous shale powder;
In the back resinous shale powder that sieves, add enzymatic microorganism then by prescription, after evenly stirring, the straw powder, medical stone powder, wheat bran, the urea that add in the prescription mix, mixed composite powder carries out spontaneous fermentation between 50 ℃~70 ℃ degree of temperature, by after the fermentation in 7~8 days composite powder being placed the cylinder dryer, temperature remains between 70 ℃~100 ℃, promptly makes the resinous shale powder raw material after the oven dry.
Step 2, with vitriolate of tartar, calcium superphosphate in the resinous shale powder raw material made and the prescription, sal epsom fully mixes, and it is that the granulating disc of 16r/min~20r/min carries out granulation that the mixture that obtains is sent into rotating speed, promptly gets fertiliser granulates;
Step 3, the fertiliser granulates that causes type is inserted drying machine with conveying belt dry, the drying machine rotating speed is 5r/min~6r/min, and bake out temperature remains on 60 ℃~80 ℃, the fertiliser granulates that comes out from drying machine is by the separating screen sorting, packs, checks, seals and get product.
The present invention passes through high temperature detoxification ball milling powdering with resinous shale, contain organic matter behind the biological fermentation, effective silicon, add the required calcium of plant, phosphorus, magnesium, potassic fertilizer, by strict production technique program, make the organic matter of resinous shale and effectively silicon increase, strengthened the fertilizer product biological activity, can directly be absorbed by plant, the toxic chemical substance that can also decompose synthetic, the nutritions such as phosphorus potassium of having degraded and being cured in Chemical Composition such as fertilizer and pesticide and the dissolving soil, increase available nutrient of soil content, organic content improves the crumb structure and the microbial ecological balance of soil, strengthen permeability and protect fertile water retention capacity, impel plant-growth, decompose remains of pesticide, solved in the soil disease problem crop.
Adopt organosilicon fertilizer of the present invention can reduce the usage quantity of agricultural chemicals, improved agricultural output, improved quality of agricultural product, eliminated fertilizer and pesticide and soil is formed harden and pollute, cause plant-growth enabling environment finally to reach the culture fertility of improving the soil, realize the agricultural year high-quality.
