Description
Technical field
The present invention relates to a kind of technical field of fertilizers, particularly a kind of Liquid Fertilizer being incubated fertilizer conservation and preparation method thereof.
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 a kind of Liquid Fertilizer being incubated fertilizer conservation 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: rape stalk powdered carbon 38-42, whey powder 6-8, potassium pyrophosphate 5-7, double superhosphate 9-13, rice bran 55-65, vinegar grain 40-46, discarded livestock and poultry feather 90-110, copper sulfate 4-5, ferrous sulfate 6-7, GM microbial preparation 5-6, 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 270-290 minute;
(2) step 1 gained two kinds of microwave hydrolysis liquid are mixed and stir, filtration obtains hydrolysis clear liquid and organic detritus, whey powder, 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 65-75 DEG C of reaction 40-60 minute, obtaining composite aminoacid chelating liquid, for subsequent use;
(3) step 2 gained organic detritus is mixed with rape stalk powdered carbon, rice bran, vinegar grain, put in fermentation vat, add suitable quantity of water and make fermentation heap water content control be 40-45%, compost fermentation 30-50 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, stir to be placed in gas-permeable container and place 24-30 hour, period constantly stirs, then filters with double gauze, obtains aerobic composting extracting solution;
(5) by step 2 gained composite aminoacid chelating liquid, step 4 gained compost extracting solution, potassium pyrophosphate, double superhosphate and leftover materials mixing and stirring, gained liquid fertilizer is placed in magnetizer under 480-520mT field intensity, magnetizes 8-12 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:
In compost leaching process, aeration condition improves microbic activity, is conducive to the raising of degree of humification, and a large amount of class plant hormones wherein comprised can play a significant role in the growth-promoting effect of crop.
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 by the interpolation of rice bran, stalk powdered carbon, vinegar grain etc., add the organic colloid content in fertilizer, life-time service can increase the adsorption surface of soil greatly, binder soil soil particle, is formed and stablizes crumb structure, improve the effect of soil in water conservation, fertilizer conservation, ventilation etc., strengthen crop root to grow, adding of a large amount of organic soil ulmin also add the surge capability of soil to temperature, reduces day and night temperature, optimizes the growing environment of crop.
