Background technology
Coating agent for seed is made through processes by pesticide original medicine (sterilant, sterilant etc.), fertilizer, growth regulator, membrane-forming agent and auxiliary aid; can directly or after dilution be coated on seed-coat, form the pesticide preparation of the protection tunic with some strength and permeability.It is one of main source of infection of crop pest generation that crop seeds carries disease germs, seed pelleting is efficient, economic, safety, multi-functional pest control method, has the percentage of germination of raising, strengthens seed vitality, alleviates environmental pollution, reduces the comprehensive effectivenesses such as cost accounting.
Along with the adjustment of pattern of farming, peanut cultivation area constantly expands in recent years, but because peanut kind passes, soil-borne disease occurs seriously, has affected the development that peanut is produced; Peanut is emerged does not become the principal element that restriction peanut yield improves entirely; Existing Drug coating, particularly, for the Drug coating of peanut seed, because its component is unreasonable, does not reach best effect, particularly promoting in seed germination, sterilizing disease-preventing function, or manufacturing cost is too high, and Higher output is not accompanied by a higher income.
Summary of the invention
For solving problems of the prior art, the present invention aims to provide and a kind ofly can promote seed germination, sterilizing disease-preventing is effective, cost performance is high and can improves the peanut seed Drug coating that Soil structure promotes nutrition absorption.
For completing above-mentioned purpose, the technology used in the present invention means are: a kind of peanut seed Drug coating, by filmogen, trace element, plant-growth regulator, sterilant, sterilant, water, formed, and described filmogen is chitin; Trace element is boron, molybdenum, iron, zinc and copper; Plant-growth regulator is growth hormone or Plant hormones regulators,gibberellins; When sterilant is happy for fitting; Sterilant is Provado; The mass percent of described peanut seed Drug coating is: chitin 1.5-3%; Ammonium molybdate 0.1-0.15%, boric acid 0.1-0.15%, ferrous sulfate 0.2%-0.3%, zinc sulfate 0.05-0.1%, copper sulfate 0.05-0.1%; Plant-growth regulator is the growth hormone of 0.000075-0.00015% or the Plant hormones regulators,gibberellins of 0.01-0.015%; When suitable happy, be 4%; Provado is 2.5%, and surplus is water.
Further, the usage ratio of described peanut seed Drug coating and peanut seed is between 1:2~1:3, peanut seed is placed in to peanut seed Drug coating and soaks 20-25 minute, dries rear sowing or placement, storage.
The invention has the beneficial effects as follows: rational proportioning, make this prescription cost performance high, contain desinsection, microbial inoculum that interior absorption is very strong simultaneously, contain again the required trace element of seed germination and growth regulator, by filmogen, adsorbed and anchored at seed-coat, slow release again after planting seed, plays sterilizing disease-preventing, improves seed vitality, promotes the effect of seed germination, percentage of germination significantly provides, and the effect of increasing income is obvious.Application peanut seed Drug coating also can improve peanut rhizosphere Soil structure, promotes absorption and the utilization of peanut Rhizosphere soil nutrient.
Embodiment
embodiment 1
Standby water 1000g, takes chitin 16g, ammonium molybdate 1g, and boric acid 1g, ferrous sulfate 2g, zinc sulfate 1g, copper sulfate 0.5g, growth hormone 0.0015g, 40ml when suitable happy, Provado 25g is added to the water and stirs under 20 ℃ of conditions, can obtain pasty state Drug coating.
2.5kg peanut seed (kind is educated No. 33 for spending) is placed in to peanut seed Drug coating and soaks 20 minutes, after drying, can sow.Coating seeds also can be placed and preserve.
Peanut after peanut seed Drug coating Cotton seeds of the present invention compared with the control percentage of germination improves 32.8%, and output improves 19%, and per hectare increases income 3600 yuan of Renminbi.Peanut rhizosphere total soil nitrogen, rapid available phosphorus and quick-acting potassium content after Drug coating is processed show to promote peanut absorbing soil-like after dressing lower than control treatment.

Standby water 1000g, takes chitin 16g, ammonium molybdate 1g, and boric acid 1g, ferrous sulfate 2g, zinc sulfate 1g, copper sulfate 0.5g, Plant hormones regulators,gibberellins 0.1g, 40ml when suitable happy, Provado 25g is added to the water and stirs under 20 ℃ of conditions, can obtain pasty state Drug coating.
3kg flower is educated to No. 33 peanut seeds and be placed in peanut seed Drug coating and soak 25 minutes, dry rear sowing.
Peanut after peanut seed Drug coating Cotton seeds of the present invention compared with the control percentage of germination improves 28.6%, and output improves 14%, and per hectare increases income 2520 yuan of Renminbi.Peanut Rhizospheric microorganisms' quantity after Drug coating is processed increases, and has suppressed the breeding of fungi in soil.

In the component adopting in the application, chitin is a kind of natural polysaecharides macromolecular compound, application is as new plant growth regulator, soil improvement agent and Plant diseases resistance inductor etc., chitin can inducing plant produce the resistance of wide spectrum, strengthen plant self-defence ability, suppress the growth of various plants pathogenic micro-organism.
Trace element has vital role to plant growth, and the trace element deficiency in soil cause production declining, more affect the quality of crop.To micro-requirement seldom, and the specificity of its effect is stronger for crop.Trace element, as the moiety of plant materials endoenzyme or coenzyme, can promote the photosynthesis of plant.Can participate in carbon nitrogen metabolism in body, participate in the redox reaction in body, promote the growth of biological nitrogen fixation, reproductive organ etc.
From above-described embodiment, can find out, the present invention is by rational proportioning, make this prescription cost performance high, contain desinsection, microbial inoculum that interior absorption is very strong simultaneously, contain again the required trace element of seed germination and growth regulator, by filmogen, adsorb and anchor at seed-coat, slow release again after planting seed, play the effect of sterilizing disease-preventing, raising seed vitality, promotion seed germination, percentage of germination significantly provides, and the effect of increasing income is obvious.
