Description
Technical field
The present invention relates to a kind of water-maintaining humic acid biological fertilizer and preparation method, belong to fertilizer field.
Background technology
In the past few decades, due to the pressure of increases in grain production, China has to improve the multiple crop index in agricultural land, and this makes farmland become barren in varying degrees, and one of them important indicator is exactly that organic content in soil reduces, and is badly in need of organic supplementing.The organic matter of agricultural land soil supplements most effective means for enriching biological organic fertilizer, reduces applying quantity of chemical fertilizer.Humic acid fertilizer is a kind of novel organic fertilizer material, is the developing direction of 21 century ecological agriculture fertilizer, in agriculture production, obtains the effect of obvious increasing yield and improving quality.Meanwhile, China has become the serious natural disaster of China's agricultural due to arid, the soil erosion agriculture underproduction, desertification etc. that cause.Therefore, development of new water-maintaining humic acid biological fertilizer has important practical significance.
At present, about utilizing humic acids prepare the patent documentation of water-maintaining biological organic fertilizer aspect and report few, the humic acid organic fertilizer product of single water retention property is only related to.
First vinylformic acid, linking agent, promotor, neutralizing agent, water, humic acids, urea, diammonium phosphate and Repone K mix with certain weight ratio by the preparation method that patent of invention 201410029168.5 announces a kind of water-maintaining humic acid complex fertilizer, and continuously stirring reaction; Then reactant is carried out drying at a certain temperature, crushing and screening, make water-maintaining humic acid complex fertilizer.
A kind of manufacture method with the multi-functional humic acid fertilizer of preserve moisture and fertility of patent of invention 201210573643.6 disclosure of the invention, it is characterized in that the modified oyster powder sorbent material be made up of the chitin modified oyster shell powder of microwave-assisted, the multi-functional humic acid fertilizer with preserve moisture and fertility containing oyster shell powder, chitosan, humate, polyacrylamide, organic acid Ti chelator, carbamide peroxide made composite with the water-reataining fertilizer-keeping agent be made up of humate, polyacrylamide, initiator.Although above-mentioned technology all has respective different characteristics, but all in various degree there is following problem: polyacrylamide and acrylate 10-35% etc., consumption is too large, with high costs, big area life-time service also can cause severe contamination to edatope, also forms certain threat to HUMAN HEALTH simultaneously; Contain a large amount of sodium salts in fertilizer, a large amount of use may cause the soil salinization simultaneously.
Summary of the invention
The object of the invention is, a kind of water-maintaining humic acid biological fertilizer and preparation method are provided, this organic fertilizer raw material is by weathered coal, dry sheep excrement, chemical fertilizer, wilkinite, water-holding agent and mixing microorganisms microbial inoculum, composting process, granulating process, spraying adsorption function microbial inoculum technique and low temperature drying technology is adopted to make, weathered coal in this fertilizer utilizes Coal Solid Wastes, realizes the recycling of waste; Meanwhile, use this fertilizer can fertilizing soil, improve effect of crop drought resistance ability and output.Described water-maintaining humic acid biological fertilizer contains abundant humic acids and functional microbial; Can soil be improved, improve crop yield simultaneously, improve crop quality, promote crop drought resistance ability.
A kind of water-maintaining humic acid biological fertilizer of the present invention, this organic fertilizer raw material is weathered coal 22%-40%, dry sheep excrement 50%-60%, chemical fertilizer 4%-5%, wilkinite 5%-10% and water-holding agent 1-3% by weight percentage, and in every 1kg water-maintaining humic acid biological fertilizer, spraying interpolation 30-50mL mixing microorganisms microbial inoculum is made; Wherein, described chemical fertilizer composition is urea, diammonium phosphate and potassium sulfate, and its weight ratio is urea: diammonium phosphate: potassium sulfate=2:1:1; Containing lactobacillus, bacillus megaterium, Bacillus licheniformis three kinds of microbial inoculums in described mixing microorganisms microbial inoculum, its volume ratio is lactobacillus bacterium liquid: bacillus megaterium bacterium liquid: Bacillus licheniformis liquid=1:1:1; Described water-holding agent is the mixture of polyacrylamide, sodium alginate and agar, and its mass ratio is 6:3:1.
The preparation method of described water-maintaining humic acid biological fertilizer, follows these steps to carry out:
A, be by weight percentage urea by weathered coal 22-40%, chemical fertilizer, diammonium phosphate and potassium sulfate 4-5% mix with dry sheep excrement 50-60% respectively after pulverizer fragmentation, mixed material water ratio is adjusted to 60%, carry out compost fermentation, compost 30-40 days, raw material becomes thoroughly decomposed completely;
After b, raw material pulverizing of becoming thoroughly decomposed, cross 80 mesh sieves and obtain powdery, then interpolation wilkinite 5-10% and water-holding agent are the mixture 1-3% of polyacrylamide, sodium alginate and agar, and carry out granulation after mixing, temperature 120-210 DEG C is dried to water ratio 8%, after cooling, and obtained particle;
The mixing microorganisms microbial inoculum of the every 1kg 30-50mL of c, the particle obtained by step b is sprayed, and after granular absorption function microbial inoculum, dries to water ratio 8%, packs, obtain water-maintaining humic acid biological fertilizer for temperature 55-60 DEG C.
Described mixing microorganisms microbial inoculum is by lactobacillus, bacillus megaterium, Bacillus licheniformis according to a conventional method respectively through 1:1:1 mixing by volume after slant activation, enlarged culturing, centrifugal concentrating, acquisition mixing microorganisms microbial inoculum.
Water-maintaining humic acid biological fertilizer of the present invention compared with prior art, has the following advantages and effect:
Weathered coal in water-maintaining humic acid biological of the present invention is after compost, and humic acids fully activates, and this fertilizer is rich in organic matter and part nutrient, simultaneously can meet the portion requirements of crop to nutrient, improve soil physical and chemical property simultaneously, arable land of fostering and apply fertilizer; This fertilizer, containing abundant fixed nitrogen, phosphorus decomposing, growth-promoting functional strain, uses this fertilizer can reduce nitrogenous fertilizer and uses, improves the utilising efficiency of soil phosphorus, promotes plant growth; Meanwhile, the water-holding agent that this fertilizer contains and humic acids act synergistically, and effectively can improve retention capacity of soil, improve crop drought resistance ability; The production technique of this water-maintaining humic acid biological fertilizer adopts the method for redrying, and adopt low temperature drying technology after adsorption function bacterium, the amount of survival of function yeast is far longer than standard, and this fertilizer is grain pattern, machine sowing can be adopted to apply fertilizer, be conducive to mechanize, reduce the fertilising cost of peasant.
In water-maintaining humic acid biological fertilizer of the present invention and preparation method, bacterial classification used is all purchased from Chinese agriculture Microbiological Culture Collection administrative center (Agricultural Culture Collection of China english abbreviation ACCC), bacterium numbering is respectively: lactobacillus (Sporolactobacillus laevolacticus. ACCC03229), bacillus megaterium (Bacillus megaterium. ACCC10011), Bacillus licheniformis (Bacillus, mucilaginosus. ACCC02975), in March, 2010 time buying.
