Description
Technical field
The invention belongs to fertilizer manufacture technology field, be specifically related to the moisture-retention sustained release formulation of a kind of fermentation and making method.
Background technology
In agriculture production, harmful organism be one of important factor causing grain drop in production, and spraying pesticide be prevention and elimination of disease and pests, improve grain yield, guarantee agricultural high yield effective way.There is the shortcomings such as effective constituent release rate is fast, drug effect efficiency time is short, dosage is large in traditional conventional type pesticide preparation, utilization ratio generally only has 20% ~ 30%.In order to maintain certain drug effect, just must spray higher than effective dose of medicine amount, or increase spraying times.Both easily produce poisoning like this, increase pesticide residue, harm humans health, contaminate environment, time-consuming again, very uneconomical.In addition, though agricultural water-loss reducer now has very strong water absorbing and retaining properties, not there is the necessary nutrient of crop growth.
Organic fertilizer fermentation is mainly derived from plant, imposing on soil to provide plant nutrition is the carbonaceous material of its major function, through biological substance, animals and plants waste, plant residue processing, eliminate hazardous and noxious substances wherein, be rich in a large amount of benefit materials, can increase and upgrade the soil organism, promote microbial reproduction, improving physico-chemical property and the biological activity of soil, is the Main Nutrients of pollution-free food production.
Therefore, how to produce the moisture-retention sustained release formulation of a kind of fermentation, water-holding agent and organic fermented liquid are harmonious, full nutrition can be provided for farm crop, there is strong water absorbing and retaining properties, and fertilizer efficiency be long simultaneously, nutrient loss is few, advantages of environment protection, is the technical problem to be solved in the present invention.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide the moisture-retention sustained release formulation of a kind of fermentation and making method, by herbicide pesticide etc., effectively organic composition and organic fermented liquid merge the moisture-retention sustained release formulation that the present invention obtains, fermented liquid is that the growth of plant provides sufficient organic matter, improve the disease-resistant performance of crop, the ability that discharges water that absorbs water is strong, soil water permeability, ventilation property strengthen, enhance the slow release effect of fertilizer, there is good biocompatibility, be beneficial to the Sustainable development of resource.
The technical scheme that the present invention takes is:
The moisture-retention sustained release formulation of a kind of fermentation, it is characterized in that, feed components is composed as follows according to weight fraction:
Linking agent 0.08-0.12 part that initiator 0.07-0.08 part that 100 parts, vinylformic acid, stalk fermentation liquid 15-20 part, urea 5-7 part, trifluralin 2-3 part, fomesafen 3-4 part, sepiolite 8-12 part, Sodium Persulfate and trolamine form according to weight ratio 2:3, epoxy chloropropane and dimethyl diallyl ammonium chloride form according to weight ratio 2:3, wood chip 4-6 part, borax 3-4 part, polyvinyl alcohol 3-4 part, guar gum 1.5-1.8 part.
Further, the making method of described stalk fermentation liquid is for being that 3:1:5 gets stalk, animal excrement and water composition mixture according to weight ratio, soak 8-10h, add the bacterial classification of the 0.3-0.5% be made up of according to weight ratio 2:2:1 genus bacillus, sporotrichum thermophile, yeast, add the humic acids of 3-5%, control leavening temperature is 38-40 DEG C, and interval 2h passes into a sterile air, gas material volume ratio is regulated to be 1:2,3-4 days before fermentation.
To ferment the making method of moisture-retention sustained release formulation, it is characterized in that, specifically comprise the steps:
(1) solid-liquid mixtures processed: getting urea, trifluralin, fomesafen and water preparation mass percent according to proportioning raw materials is the pesticidal emulsion of 16-18%, slowly adds sepiolite, linking agent, mixing and stirring in emulsion;
(2) integument particle processed: in the reactor, vinylformic acid mass concentration is the solution of potassium carbonate neutralization of 25%, part acrylic acid is made to be converted into potassium acrylate, add above-mentioned obtained solid-liquid mixtures, initiator successively, stir, be warming up to 60-65 ° of C, reaction keeps 4-5h to obtain gel polymerisate, drying, grinding, excessively 200 eye mesh screens;
(3) coating process: in granulating disc; put into above-mentioned obtained integument particle; open air blast feeder; add ultra-fine wood chip powder on the integument particle rolled, make it evenly be wrapping to particle surface, with the mixture of the nozzles spray borax of pressure >=0.4MPa, polyvinyl alcohol and guar gum; consumption accounts for the 1.5-3% of integument particle; temperature maintains 55 ° of C, and Hot-blast Heating, is cooled to room temperature.
Beneficial effect of the present invention is:
By herbicide pesticide etc., effectively organic composition and organic fermented liquid merge the moisture-retention sustained release formulation that the present invention obtains, fermented liquid is that the growth of plant provides sufficient organic matter, the output of the crop of improving, the effective components such as trifluralin make the resistant to diseases and insects of plant improve, improve the disease-resistant performance of crop, indirectly improve the quality of crop.
Product of the present invention is divided into inside and outside two-layer, inner sepiolite and outside wood chip all act as the effect of water conservation carrier, can improve the utilization ratio of moisture and nutrient simultaneously, and the ability that discharges water that absorbs water is strong, and it can form crumb structure in soil, soil water permeability, ventilation property are strengthened;
The present invention makes full use of stalk the like waste, turns waste into wealth, and has good biocompatibility, is beneficial to the Sustainable development of resource.
The envelope components such as polyvinyl alcohol, guar gum, enhances the slow release effect of fertilizer, improves the utilization ratio of fertilizer, nutrient can need fertile slow releasing by crop, can Soil structure be regulated, reduce the antagonism between ion, thus improve effective specific absorption of plant, reduce applying quantity of chemical fertilizer.
