Abstract
A multifunctional seed coating agent for paddy rice is prepared from filming agent, emulsifier, disperser, antifreezing agent, antiseptic, defoaming agent, insecticide, bactericide, plant growth regulator and trace element fertilizer. The invention is suitable for coating various rice seeds in different areas, different soils and different growing seasons, after seed soaking and germination accelerating, the rice seedling raising and dry seedling raising or direct seeding are carried out according to the traditional method, the prevention and control rate for rice thrips, rice planthoppers and rice gall midges reaches 90-99 percent and the prevention and control rate for bakanae disease, damping off, cotton rot and leaf spot of flax reaches 81-95 percent in the lasting period of 45-60 days, the seedlings are uniform, the tillering is more, the seedling forming rate is obviously improved, and the coated seeds can be safely stored.
Description
The present invention relates to a kind of preparation that crop seed is handled that is used for, it exactly is a kind of immersion-type multifunctional coating agent for rice seeds, it is with agricultural chemicals, fertilizer and growth regulator isoreactivity composition, the crop seed inorganic agent that nonactive compositions such as film forming agent, emulsifier, dispersant are mixed and processed.
In the plant growth cycle, always often be subjected to the threat of damage by disease and insect, particularly seedling stage diseases and pests is the problem that agricultural experts and peasant pay special attention to always, what adopted is that prior seed sterilization method such as dressing seed, seed soaking and soil disinfection method are handled in the past, though these methods have certain effect, effect is not really desirable; Adopt method for soaking seed, medicament is diluted in the water, and dosage is big, and waste is many, take dressing seed easily to cause seed dressing inhomogeneous, or to cause kind of a daughter lesion, these methods that a common problem is all arranged be the poor adhesive force of medicament on seed, seed carrying or easily come off when after planting meeting water, lasting period is short, and dosing is big, and seed disinfection is carried out in the short time prior to seeding, is difficult to realize the industrialization of seed treatment; The soil disinfection dosing is big, the cost height, and time-consuming, environmental pollution is serious.
The standardization that seed processing is handled, the important component part that modernization is modern agriculture require corresponding seed quality criteriaization, processing mechanization, the smart quantification of sowing and cultivation lightness.Early stage kind clothing agent is the agent of physical kind clothing, does not contain active ingredient, and its effect is to make that volume behind the small-sized seed dressing, weight increase, the grain type is regular, so as machine sowing, evenly broadcast, precision drilling.At the initial stage eighties at the end of the seventies, the standardization of crop seed combines with the control of seedling stage diseases and pests and has formed kind clothing agent one with Modern Significance by one or more the special-purpose seed treatments that can form the clothing film at the surface of the seed that are mixed with in nonactive compositions such as film forming agent, emulsifier, dispersant and insecticide, bactericide, fertilizer, the growth regulator isoreactivity composition.After planting plant the clothing suction at capsuled seed, its active ingredient slowly discharges, and contacts with the surface of the seed and soil, thereby kills kind of a biography, soil-borne disease and soil insect; The absorption insecticidal bactericide is absorbed by seedlings root and conducts to plant top in behind the seed germination, has continued the preventing disease pest control effect; Fertilizer, growth regulator that the while slowly-releasing goes out provide seed germination, the required nutrient of growth and development stage, and the regulation and control growth of seedlings is grown.
At present, the development and production technology of Dry crop (comprising paddy drought seedling) kind clothing agent is fairly perfect, and has obtained reasonable effect in application, but the development of dressing agent for rice remains the direction of scientific worker's main attack.Main cause is that the rice seed soaking seedling is different from the seed soaking seedling of Dry crop, and the field production mode is also different.Dressing agent for rice to filmogen in water dissolubility and the requirement of corresponding film technique be higher than the agent of dry farming species clothing far away, require kind of clothing agent water insoluble when rice paddy seed soak seed, and don't influence the seed sprouting that absorbs water.The main weak point of prior art be that the clothing film on the capsuled seed is soluble in water and cause in it active ingredient loss serious, be difficult to carry out that running water seed soaking, active ingredient lasting period are short, capsuled seed is difficult to aspects such as safe storage.
Chinese patent discloses the relevant technologies of relevant dressing agent for rice, what relate to as the CN1102944A patent publication is the agent of rice direct-seeding kind clothing, but require seed elder generation presoaking and germinating, carry out dressing again, capsuled seed can't be stored, and is difficult to realize the seed treatment industrialization, and what the CN1117343A patent publication related to also is paddy rice seed coating agent, but used film forming agent is a polyacrylamide soluble in water, and the clothing film is very easily water-soluble and cause active ingredient to lose in a large number during seed soaking.
Purpose of the present invention is exactly the above-mentioned deficiency at prior art, for different regions, different soils condition, various seasons provide a kind of each veriety of adaptation and can carry out presoaking and germinating can ruined dressing agent for rice, effective prevention and control seedling stage diseases and pests, and can urge the control growth of seedling, guarantee that seedling is neat, strong, it is many to tiller, and percentage establishment of seedling obviously improves.Capsuled seed can adopt conventional method running water presoaking and germinating, carries out that water is educated, drought is educated or live.Capsuled seed can store safely.
The present invention is achieved in that with water-fast filmogen and makes film forming agent, promptly gets immersion-type multifunctional coating agent for rice seeds with nonactive compositions such as emulsifier, dispersant, antifreezing agent, preservative, defoamer, look section and insecticide, bactericide, trace element fertilizer, plant growth regulator isoreactivity composition mixed preparing.
Described composition is:
Film forming agent: one or both film forming agents that mix in water-insoluble chitin derivativ or water-insoluble chitin derivativ and polyvinyl acetate, the acetyl cellulose, consumption (percentage by weight, down with) is .0.4-8%.When two kinds and two or more mixing, only control total amount, the relative quantity between each film forming agent is any;
Emulsifier: a kind of among Emulsifier O, polyoxyethylene nonylphenol ether or the emulsifier BS-12, consumption is 1-4%;
Dispersant: dispersant N or dispersant IW, consumption are 0.5-3%;
Antifreezing agent: ethylene glycol or propane diols, consumption are 2-6%, the suitable 4-6% of the regional consumption that temperature is low;
Preservative: mud pool tortoise beetle ester or Sodium Benzoate, consumption is 0.05-0.3%;
Defoamer: tributyl phosphate or octanol, consumption are 0.1-0.4%;

Production method of the present invention is as follows:
By the prescription requirement, film forming agent is dropped among the dissolution kettle A, pump into water, antifreezing agent and appropriate amount of acid, after the stirring and dissolving it is pumped among the modulation kettle B; Solid insecticidal, bactericide, growth regulator and the trace element fertilizer that will pass through through column mill C or in the presence of emulsifier, defoamer after ball mill D mills drops among the modulation kettle B then, stir evenly the back and add all the other all compositions, stir and transfer PH to neutral, promptly get red aqueous kind of clothing agent with ammoniacal liquor.
Mechanism of action of the present invention and characteristics:
With the present invention during to coating paddy seeds, film forming agent in the agent of kind of clothing can the surface of the seed form have the water insoluble of fenestra road but can breathe freely, permeable good clothing film, and together, thereby around seed, form one miniature " active substance storehouse " with insecticidal bactericide, growth regulator isoreactivity composition and other nonactive composition anastomose.During the capsuled seed seed soaking, water insoluble because of the clothing film, the active ingredient loss is few, and the clothing film has the fenestra road of water-permeable and air permeable, thereby seed can normally be sprouted.Behind the planting seed, under the effect of hydrone, the active ingredient in " active substance storehouse " discharges lentamente by the fenestra road utmost point and progressively contacts with seed and adjacent soil, thereby participates in the physiological and biochemical procedure of rice seedling growth and development stage.Insecticidal bactericide in " active substance storehouse " with the surface of the seed and inner the contact, kills kind of a biography germ, insect pest under the effect of water; And around seed, form the protection barrier, and the damage by disease and insect around making is difficult to existence, thus effectively control soil passes and biologies such as air borne germ, soil insect and mouse, sparrow.After emerging, long-acting interior absorption insecticidal bactericide (as Imidacloprid, dimehypo, Prochloraz, tolelofos-methyl, carbendazim etc.) in " active substance storehouse " is under emulsifier, diffusant etc. help, progressively absorbed and conduct to not dispenser position of overground part by seedlings root, continued the preventing disease pest control effect, thus effective prevention and control rice seedling damage by disease and insect.Because the efficacy of a drug is concentrated, availability is higher, contacts with soil in addition, be not subject to expose to the sun and rain and the influence of high temperature, thereby the drug effect phase reach 45-60 days, seedling stage substantially needn't dispenser, saving of work and time; Add that high-toxic pesticide is wrapped in the film, make it low and poison, insecticide-applying way is by the open hidden that becomes, thus can effectively reduce people and animals, pest natural enemy the poisoning chance, reduce environmental pollution.Growth hormone methyl in " active substance storehouse ", heteroauxin can promote to sprout, promote root growth, improve emergence rate, resistance and planting percent; Growth retardant paclobutrazol, uniconazole P can be alleviated an end growth vigor, promote to tiller, increase thick cane, promote well developed root system, thus raising rate in strong sprout, for volume increase lays the first stone.Trace element fertilizer zinc in " active substance storehouse ", manganese, boron fertilizer can remedy the soil fertility deficiency, satisfy the required trace element of rice shoot normal growth, effectively prevent and treat nutritional deficiency disease.
The present invention proves through indoor pot, sub-district, field and field experiment: behind the capsuled seed presoaking and germinating no matter be that water is educated, drought is educated or live, in 45-60 days lasting period, the control rate of rice thrips, rice fulgorid, rice gall midge reached 90-99%; Control rate to bakanae disease, pythium rot, oriental sesame leaf pinta, damping off reaches 81-95%.Germination rate, percentage establishment of seedling, strong seedling rate, tillering obviously exceeds control group, and wherein the germination rate comparison is according to high 1-5 percentage point, the high 8-15% of percentage establishment of seedling.Production technology of the present invention is simple, and cost is lower, and raw material is easy to get, but capsuled seed safe storage 8-14 month.
