Abstract
A slowly-released filming agent used as seed-coating agent or root-immersing agent, or used to coating plant branch for holding water or moisture is prepared from high-molecular polymer, excipient and auxiliary materials, and features that it forms as semi-permeable film and after it absorbs water, it can expand but not be dissolved in water.
Description
A kind of slowly-released film forming agent belongs to seed pelleting, plant and soaks branch or root film forming agent.
Seed pelleting, plant are soaked time that the research of branch or the capsulating material used of root carries out soon, are mainly seen in the seed treatment of crops at present, as the seed coating medicine that corn, wheat, radish, Chinese cabbage etc. crops seed are used, also cry the agent of kind clothing.Relevant plant soaks branch or root yet there are no report with the research of capsulating material.Seed also mostly is water-soluble material (works such as Gao Jiaming " effect of increasing production in strong sprout of corn seed coating agent " " Henan agricultural science " with the material of seed coating medicine; the tenth phase of nineteen ninety-five 13-14 page or leaf, ZL91100684.2 patent, ZL92106646.5 patent); it is easily dissolved to meet water; enduring quality is relatively poor in soil, can not implement effectively to the protection of seed with to the slow releasing function of effective ingredients such as medicine.
The object of the present invention is to provide a kind of slowly-released film forming agent that can form one deck densification, pliable and tough, continuous film clothing on the root of seed or plant, branch surface.
Key component in the film forming agent of the present invention is polyvinyl acetate saponified (A), melmac (B), excipient (C) and auxiliary material (D).Component A and B component all belong to high molecular polymer, and excipient is a sodium carboxymethylcellulose, and gum Arabic or other water soluble excipients (requiring viscosity greater than 250-350Pas, 25 ℃) auxiliary material (D) is famille rose or iron oxide red, mainly plays the warning colouration effect.
Film forming agent of the present invention, by weight percentage, component A accounts for the 2.20-3.80% of total amount, and B component accounts for the 0.04-0.18% of total amount, and component C accounts for the 0.50-2.80% of total amount, and component D accounts for the 1.80-2.00% of total amount.Compound method is: will gather the rare saponified and melmac mixing of acetate second earlier, and add suitable quantity of water and stir, 80-100 ℃ of heating made it to cool off under dissolving, the static room temperature in 3-5 minute; Sodium carboxymethylcellulose or sodium carboxymethylcellulose and gum Arabic (or other water soluble excipients) were by 1: 4 proportioning, the mixing back adds 3-5 times water infiltration 10-15 hour, adds suitable quantity of water again and stirs, and at last two kinds of solution is mixed, add appropriate amount of auxiliary materials, stir and get final product.
Film forming agent of the present invention has semipermeable membrane character, water absorbing properties is good, a suction back swelling and be difficult for being separated by water-soluble, bag is by back difficult drop-off on plant branch, root or seed, can increase water conservation, the moisture-retaining capacity of plant in soil, improve the drought resisting performance, agricultural chemicals, little fertilizer, hormone or other nutrient components etc. in the interpolation, can be made into branch, root or seed slowly-releasing coating agent, improve percentage of seedgermination, prevent and treat underground disease, insect pest effectively, promote root growth and nutrition supply, reach the active ingredient slowly-releasing and make full use of, satisfy the demand of encrusting substance different times.
Film forming agent of the present invention is equipped with compositions such as Isofenphos methyl missible oil, triazolone missible oil, sodium-para-nitrophenolate, carbendazim missible oil, paclobutrazol and can be made into the slowly-releasing coating agent.Heterogeneity and proportioning can make seed coating agents such as being used for corn, wheat, cotton and vegetables respectively, prevent and treat insects such as mole cricket, aphid, corn borer effectively.0.40-0.75 Isofenphos methyl missible oil+0.30-0.60% triazolone missible oil+1.50-2.25% sodium-para-nitrophenolate+0.40-0.75% carbendazim missible oil+0.10-0.18% paclobutrazol and film forming agent proportioning, the corn seed slowly-releasing coating agent of making can make maize root system increase by 31.5%/strain, and output increases more than 16.3%.With 0.35-0.80% Isofenphos methyl missible oil+0.40-0.85% triazolone missible oil+1.50-2.75% sodium-para-nitrophenolate+0.10-0.18% paclobutrazol and film forming agent proportioning, wheat seed slowly-releasing coating agent of making and vegetable seeds slowly-releasing coating agent, through the test contrast, all obtain remarkable result.
Film forming agent of the present invention is equipped with heteroauxin (10-80PPm), the α-Nai Yisuan components such as (75-180PPm) with dissolve with ethanol, makes the liquid film of taking root, and is applicable to intercutting of flowers such as tea, mulberry, arbor-vitae, metasequoia.To intercut axis bar stem (3-5cm) and immerse film 10 minutes, the effect that can reach buries takes root.
