The invention discloses a liquid fertilizer with high utilization rate, which is prepared from the following raw materials in parts by weight: 53-57 parts of bran coat, 6-9 parts of ammonium sulfate nitrate, 40-44 parts of sesame cake meal, 2-4 parts of zinc sulfate, 6-7 parts of lactic acid, 20-25 parts of pepper seeds, 125-135 parts of waste livestock and poultry feather, 4-6 parts of copper sulfate, 5-7 parts of ferrous sulfate, 3-6 parts of GM microbial agent and a proper amount of water; the liquid fertilizer is prepared by compounding a plurality of organic raw materials and inorganic nutrients, is comprehensive in nutrition and can supplement various elements required by crops, the content of active substances of the liquid fertilizer is increased by adding pepper seeds, lactic acid and the like, so that the liquid fertilizer has strong complexing capability, activates an inorganic phosphorus library in soil, reduces volatilization, denitrification and other effects of nitrogen, further improves the utilization rate of the nutrients by the crops, has strong water solubility, cannot generate precipitation to block drip holes when in use, and has excellent service performance.
Description
Technical field
The present invention relates to a kind of technical field of fertilizers, particularly a kind of Liquid Fertilizer and preparation method thereof of high utilization rate.
Background technology
China is as large agricultural country, and agriculture production plays vital effect to national economy, and fertilizer is the important factor affecting agriculture production yield and quality.But most fertilizer existing defects in nutritive ingredient in the market, namely while raising output, some nutriment is caused not catch up with demand, or lay particular emphasis on stimulation plant growth, cause nutritional deficiency disease etc., cause the resistance of crop poor, output reduces and quality decline, cannot meet the demand of present stage agriculture production.
Compost extracting solution refers to the aqueous extract of the organic materials of decomposition reactor system after diverse ways extracts, can not only Promoting plant growth, improve crop quality and increase crop yield, and have obvious inhibition to soil-borne pathogen, a kind of effective means of alternative chemical pesticide control certain plants disease can be developed into, there is the effect of fertile medicine unification.Be different from compost to be manured into soil, compost extracting solution can fill with root also can foliage-spray, and using method is simple and save labor force.
Therefore, the present inventor utilizes compost extracting solution and has prepared a kind of novel liquid fertilizer in conjunction with kinds of processes, in nutritive ingredient with functionally there is larger improvement, to adapt to the needs of agricultural cultivation under conditions present, significant promoter action is all brought to the high yield of farm crop and high-quality, and technical support is provided to the ecological agriculture of development green health, promote and improve the development of agricultural.
Summary of the invention
The present invention compensate for the deficiencies in the prior art, provides Liquid Fertilizer of a kind of high utilization rate and preparation method thereof.
Technical scheme of the present invention is as follows:
Liquid fertilizer of the present invention is made up of the raw material of following weight part: cavings 53-57, ammonium sulfate nitrate 6-9, sesame cake meal 40-44, zinc sulfate 2-4, lactic acid 6-7, Semen Pericarpium Zanthoxyli 20-25, discarded livestock and poultry feather 125-135, copper sulfate 4-6, ferrous sulfate 5-7, GM microbial preparation 3-6, water are appropriate.
The concrete steps of the preparation of described liquid fertilizer are as follows:
(1) equiponderant two parts are divided into after discarded livestock and poultry feather being cleaned oven dry pulverizing, portion adds the 3mol/L sulphuric acid soln of 10 times of weight, be placed in microwave oven microwave hydrolysis 220-260 minute, another part adds in the 6mol/L potassium hydroxide solution of 10 times of weight, is placed in microwave oven microwave hydrolysis 260-300 minute;
(2) step 1 gained two kinds of microwave hydrolysis liquid are mixed and stir, filtration obtains hydrolysis clear liquid and organic detritus, lactic acid, copper sulfate is added again in hydrolysis clear liquid, PH is adjusted to 6.0,70-90 minute is reacted at being heated to 50-60 DEG C, add ferrous sulfate again and be warming up to 65-70 DEG C of reaction 40-60 minute, obtaining composite aminoacid chelating liquid, for subsequent use;
(3) step 2 gained organic detritus is mixed with Semen Pericarpium Zanthoxyli, cavings, sesame cake meal, put in fermentation vat, add suitable quantity of water and make fermentation heap water content control be 45-55%, compost fermentation 35-55 days, take out after fully becoming thoroughly decomposed;
(4) in step 3 gained compost, pass into the water of 8-10 times of weight and add GM microbial preparation, stirring to be placed in encloses container and place 6-8 days, then filtering with double gauze, obtaining lonely compost extracting solution;
(5) by step 2 gained composite aminoacid chelating liquid, step 4 gained compost extracting solution, zinc sulfate, ammonium sulfate nitrate and leftover materials mixing and stirring, gained liquid fertilizer is placed in magnetizer under 470-530mT field intensity, magnetizes 8-10 minute, obtain liquid fertilizer of the present invention.
Be means with microwave heating in preparation process, the mode of its heating substantially reduces hydrolysis time, reduce the consumption of energy consumption and hydrolysising solvent, hydrolysis material is carried out respectively with sulphuric acid soln and potassium hydroxide solution, then the hydrolyzed solution neutralization under two kinds of different conditions, the a large amount of acid-base waste fluids produced after can eliminating hydrolysis, and compensate for the loss of the partial amino-acid kind caused in different hydrolysis medium Water Under solution, improve liquid fertilizer fertilizer efficiency.
In preparation process, compost is residue obtained owing to becoming thoroughly decomposed fully after filtering, directly can use as fertilizer, achieve the maximum using of resource, and can play purification repair to edatope.
The using method of liquid fertilizer of the present invention is root drip irrigation or foliage-spray, and consumption is every mu of 2000-2500kg.
Beneficial effect of the present invention:
Use anaerobic condition can reduce dissolved oxygen content in extracting solution in compost leaching process, restriction organic matter and available nutrient by a large amount of decomposition and consumption of microorganism, thus improve npk nutrient content in liquid fertilizer.
Liquid internal is made to divide hydrogen bond rupture to the energy of magnetization of liquid fertilizer in preparation process, add the quantity of hydrone in liquid fertilizer system, diminishing of water molecules, the dissolved oxygen amount of liquid fertilizer is increased, and diffusibility strengthens, and more easily enters and do in object in the activity of Crop nutrition, accelerate the transport of nutrition, promote photosynthesis, manufacture more multiple nutrient matter, to promote growing of crop.
Liquid fertilizer of the present invention is through multiple organic raw material and inorganic nutriment is composite forms, prepared by the technique through multistep science, comprehensive nutrition, the various elements of crop demand can be supplemented, the interpolation of Semen Pericarpium Zanthoxyli, lactic acid etc. adds the activity substance content of liquid fertilizer, make it have stronger complex ability, and the inorganic phosphorus storehouse in activating soil, reduce the effect such as volatilization, denitrification of nitrogen, and then improve crop to the utilization ratio of nutrient, this liquid fertilizer is by force water-soluble simultaneously, precipitation can not occur during use and block drip hole, has excellent use properties.
