Abstract

The invention discloses liquid fertilizer for promoting soil microelement uptake by crops. The liquid fertilizer comprises, by weight, 14-16 parts of maple syrup, 36-40 parts of lobster shells, 3-4 parts of sodium selenite, 40-50 parts of eggshell powder, 34-38 parts of sawdust, 13-16 parts of potassium hydrogen phosphate, 140-150 parts of wasted feather of beasts and birds, 3-4 parts of copper sulfate, 5-7 parts of ferrous sulfate, 3-5 parts of GM microbial preparation and a proper amount of water. According to the liquid fertilizer, the eggshell powder, the lobster shells and other wasted materials are fully utilized, nutrient substances capable of being absorbed by the crops are recycled through multiple steps of processes, meanwhile the added maple syrup and the like contain multiple kinds of active groups and can form coordination compounds in cooperation with medium trace elements in soil, especially iron and zinc, the nutrient element uptake by the crops is facilitated, a large number of highly-active microorganisms are added to the liquid fertilizer, the dominant population function can be played after the liquid fertilizer is used, and the healthy state of the growth environment of the crops is guaranteed.

Description

A kind ofly promote that crop is to Liquid Fertilizer that soil trace element absorbs and preparation method thereof

Technical field

The present invention relates to a kind of technical field of fertilizers, particularly a kind ofly promote that crop is to Liquid Fertilizer that soil trace element absorbs 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 and promotes that crop is to Liquid Fertilizer that soil trace element absorbs 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: maple syrup 14-16, lobster shell 36-40, Sodium Selenite 3-4, egg-shell meal 40-50, wood sawdust 34-38, potassium phosphate,monobasic 13-16, discarded livestock and poultry feather 140-150, copper sulfate 3-4, ferrous sulfate 5-7, GM microbial preparation 3-5, 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 260-280 minute;

(2) step 1 gained two kinds of microwave hydrolysis liquid are mixed and stir, filtration obtains hydrolysis clear liquid and organic detritus, maple syrup, copper sulfate is added again in hydrolysis clear liquid, PH is adjusted to 6.0,70-80 minute is reacted at being heated to 55-60 DEG C, add ferrous sulfate again and be warming up to 75-80 DEG C of reaction 50-60 minute, obtaining composite aminoacid chelating liquid, for subsequent use;

(3) step 2 gained organic detritus is mixed with egg-shell meal, wood sawdust, lobster shell, put in fermentation vat, add suitable quantity of water and make fermentation heap water content control be 45-55%, 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 28-32 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, Sodium Selenite, potassium phosphate,monobasic and leftover materials mixing and stirring, gained liquid fertilizer is placed in magnetizer under 450-550mT 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:

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 takes full advantage of the waste material such as egg-shell meal, lobster shell, the wherein absorbable nutritive substance of crop has been reclaimed through multi-step process, the maple syrup simultaneously added etc. are containing various active group, coordination compound can be formed with Trace Elements in Soil, particularly iron and zinc, contributes to the absorption of crop to nutritive element, with the addition of again a greater number and highly active microorganism in liquid fertilizer, can to make the most of the advantage after a procedure population effect, to have ensured the healthy state of crop growth environment.
