Description
Technical field:
The invention discloses a kind of coating agent for seed, particularly a kind of coating agent for seed that is applicable to cereal crops seed.
Background technology:
Seed coating technology is by China agricultural experts, to be praised highly energetically the agricultural production new technology with vast farmers popular welcome in recent years, and in the production time, has obtained very good effect.Packaging technique is the important means of building High yield agricultural modernization and agricultural sustainable development, and the kind clothing of commercial seed is one of important technique measure moving up the technology ladder with the level of production.Therefore find a kind of can volume increase again by disease and insect resistance, environment amenable coating agent for seed is the problem that people study always simultaneously.
Deep research has been done to the nuisanceless seed coating medicine for gourd vegetable crop by Shanghai University Of Engineering Science, its patent publication No. is CN1631151, China Agricultural University adopts fulvic acid to further investigate seeds of leguminous plant seed coating medicine and preparation method, can significantly improve the survival of rhizobium and the competitiveness of microorganism, its patent publication No. is CN102070368A; A kind of coating agent for seed that cycloheximide is active ingredient of take has been researched and developed in Shanghai Pesticide Research Institute, effective protection against rodents, and for agricultural, its patent publication No. is CN1843118.
Gamma-polyglutamic acid-is a kind of multifunctional bio degradable high polymer material being combined into by the amido link between alpha-amido and γ-carboxyl by D-Glu and Pidolidone.Because gamma-polyglutamic acid-and derivative thereof have good water-soluble and adsorptivity, can thoroughly be biodegradable, to humans and animals safety non-toxic, the advantage such as edible, thereby can be used as the functions such as water-loss reducer, thickener, flocculant, heavy metal absorbent, medicine/fertilizer slow-release formulation and pharmaceutical carrier.Although the kind of coating agent for seed is many both at home and abroad, the coating agent for seed that the gamma-polyglutamic acid-of take is active ingredient is at present there are no report.
Summary of the invention:
The present invention is by providing a kind of cereal crops seed that is applicable to, and the coating agent for seed that contains gamma-polyglutamic acid-, has solved the problem that existing vegetables and cereal crops coating agent for seed can cause environmental pollution.
Coating agent for seed of the present invention comprises following component: (content represents with weight percentage)
Wherein, described gamma-polyglutamic acid-is technical grade commercial goods, and molecular weight is 50,000 ~ 80,000 Da.
Described dispersant is polyvinyl alcohol.
Described adhesive is hydroxypropyl methylcellulose and methylcellulose, and mass ratio is 5:1.
Described surfactant is polyoxyethylene alkyl ether, as OP
20.
Described biocide is at least one in carbendazim, tmtd, carbofuran.
In order to show seed treatment situation, in above-mentioned composition, add warning property dyestuff, described warning dyestuff is gentian violet.
Utilize coating agent for seed of the present invention to process seed, described coating agent for seed each component is added and mixed in proportion, coating agent for seed and seed are according to the ratio of mass ratio 1:30-100, with the manual dressing of existing packaging technique or mechanical dressing.
Beneficial effect:
The coating agent for seed that the polyglutamic acid of take is main component, can improve the microenvironment of seed growth, can promote growing of seed sprouting and seedling, improve seedling quality, improve pesticide efficacy, reduce the diffusion of agricultural chemicals in environment and the Exposure of non-target, on blade face, do not have residual, the effect that improves seed coat agent preventing disease pest control, meets the requirement of green ecological agricultural development.
Seed coating medicine of the present invention adopts prior art formulated through being uniformly mixed, and can be widely used in agricultural, forestry etc., improves output.Seed coating medicine of the present invention also has good film forming and slow-release function, there are higher one-tenth film-strength and water suction resistance to water and chemical stability, with plant, particularly there is good biocompatibility with crops, this is suitable for plant to building, the microenvironment of particularly growing with crops root system is very favourable, and the present invention can not affect the eupnea of seed, thereby can not affect the germination rate of seed.
The expulsion rate of the dry caudacoria of seed coating medicine of the present invention is low, can in soil, slowly discharge farm chemical ingredients, seed coating medicine of the present invention has unique water-absorbing-retaining slow releasing function, can improve the microenvironment of seed growth, thereby promote growing of seed sprouting and seedling, improve seedling quality.In seed germination, seedling development process, slowly discharge active ingredient simultaneously, improve pesticide efficacy, guarantee that limited farm chemical ingredients concentrates on seed and root, reduce the diffusion of agricultural chemicals in environment and the Exposure of non-target, improve the effect of seed coat agent preventing disease pest control.
