Description
Technical field
The invention belongs to technical field of pesticide preparations, more particularly to a kind of preparation method of seed coat agent.
Background technology
By dry or moisture state seed, wrapped with the composition pesticide containing binding agent, make to form tool outside seed
There is certain function and coat the protective layer of intensity, this process is known as seed pelleting, wraps the combination material outside seed and be referred to as
For seed coat agent.Seed coat agent grows up on the basis of seed dressing and seed soaking agent, its great advantage be can outside seed shape
Into one layer of more firm film, hence obtain one's name seed coat agent.Seed coat agent has liquid, also there is solid powdery；Have plenty of pre-
Type is made to store for a long time, the now-making-now-using also having, there is suspension seed-coating agent（FS）, powder（DP）Seed coat agent, Ultramicro-powder（UP）Kind clothing
Agent, microemulsion（ME）Seed coat agent, aqueous emulsion（EW）Seed coat agent etc..Wherein, suspension seed-coating agent（FS）Preparation processing is convenient, plants attached bag
Clothing effect is good, is adapted to pesticide active ingredient Recompounded multielement, is the seed coat agent agent being most widely used in current seed pelleting processing
Type.With this medicament to seed pelleting, the invasion and attack of disease pest in soil can be after planting prevented, meanwhile, as germination is unearthed, medicament
Gradually discharge, be absorbed by crops from kind of clothing, can also prevent overground part pest and disease damage.
Seed coat agent is more with multi-functional, prevention multiple diseases joint product type seed coat agent, and disease pest composite seed coating agent accounts for
40% or so of seed coat agent kind, in addition with some medicine fertilizer composite seed coating agents.Seed coat agent market forms：Corn accounts for 48%,
Wheat accounts for 24%, and soybean accounts for 10%, and cotton accounts for 8%, and rice accounts for 5%, other account for 5%.
Seed coat agent mainly includes following component at present：Pesticide activity component, wetting dispersing agent, film forming agent, colouring agent, defoaming
Agent, thickener, water etc., common pesticide activity component has Diacloden and difenoconazole in seed coat agent, and common film forming agent has
More carbohydrates and their derivatives, such as gum arabic, cellulose derivative, gelatin, starch derivatives；More also have and bond
The polymer of property and film forming, such as polyvinyl alcohol（PVA）, ethylene-vinyl acetate copolymer（VAE）, polyvinyl acetate resin, third
Olefin(e) acid resin etc., the pest and disease damage of crops seedling stage is prevented using the seed pelletings such as dressing seed, seed soaking and sterilization method, these
Although having certain effect to seed pest and disease damage, these medicaments are easy to run off coming off, and efficiency time is short, and easily lead to the mold of seed,
Therefore, it is extremely urgent to invent a kind of seed coat agent of efficiently protection seed.
The content of the invention
The technical problems to be solved by the invention：It is easy to run off coming off for current seed coat agent, efficiency time is short, and easily leads to
A kind of the problem of mold of seed, there is provided preparation method of seed coat agent.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of preparation method of seed coat agent, the preparation method include the following steps：
（1）In mass ratio 1：4~7, take Sargassum horneri and addition powder to stir evenly, and be dried, dried object is collected, by weight

（5）After question response, reaction mixture is collected, and is filtered, smoke filtrate is collected, smoke filtrate is concentrated, is received
Collect concentrate, up to seed coat agent.
The step（1）Middle addition powder is tobacco leaf and tealeaves in mass ratio 1：2 are dried, and crush, and sieving, was collected
Particle is sieved, up to powder is added.
The step（1）Middle bacterium powder is yeast bacterium powder, gibberella powder in mass ratio 3：1 mixes.
The step（1）Middle mixing bean powder is in mass ratio 6：2~4, flower beans, soya bean are put into pulverizer and crushed, i.e.,
Bean powder must be mixed.
The step（2）Herb powder is in mass ratio 1：2~4：3~5, by pseudo-ginseng, indigo naturalis and folium isatidis co-grinding
Form.
Compared with other methods, advantageous effects are the present invention：
The present invention carries out fermentation extraction by strain to Sargassum horneri, tobacco leaf and tealeaves, on the one hand obtains micronutrient element therein,
Increase the trophic component component in seed coat agent, another side obtains stimulus, improves the germination efficiency of seed, and fermentation process
It is middle to add mixing bean powder, abundant amino acid and colloid class material are obtained by mixing bean powder, improves the film forming of seed coat agent, and
And acquisition amino acid can promote neutron absorption, increase the formation of heteroauxin, increase the sprouting of seed, then reuse three second
Base amino silane, bromoethane etc. are modified the colloid class material in extract, increase water resistance, improve seed coat agent film forming
Stability afterwards, reduces and departs from efficiency, while the generation for having gibberellin in fermenting improves the sprouting performance of seed, and utilizes
Geniposide makes protein and colloid class material carry out crosslinking and carry out increase filming performance, and Chinese medical extract is added in film forming procedure,
Anti-microbial property is improved, prevents seed from being encroached on by microorganism, adds efficiency time.
