Description

Drought-resistant seed compound coating agent and preparation method
The present invention relates to the mixture of anti-drought water-retaining agent, agricultural chemicals, little fertilizer and multiple auxiliary agent, exactly is a kind of seed coating medicine that the plant breeding is handled that is used for.
Existing coating agent for seed; the fertile composite type seed seed coating medicine of medicine (patent publication No. is CN86100095A) as Beijing Agricultural University's invention contains agricultural chemicals, little fertilizer, trace element, auxin and other auxiliary aids; can around seed, form the protection barrier of prevention and elimination of disease and pests; control soil passes, kind passes sick the erosion; after treating that seed sprouting is unearthed; medicine is fertile slowly to be discharged, and continues preventing disease pest control and fertilizer efficiency effect.Its deficiency is to lack drought resistance function.Be head it off, on April 14th, 1993 disclosed a kind of " drought-resistant seed compound coating agent " (CN1070799) by Patent Office of the People's Republic of China.This coating agent for seed " contains agricultural chemicals, little fertilizer, trace element, auxin, colloid dispersant and water.It is characterized in that also containing the super absorbent resin of 3%-4.5% (percentage by weight)." wherein " said agricultural chemicals is certain two kinds in tpn, carbendazim, furans pellet, triazolone, the Isofenphos methyl, said little fertilizer is diammonium hydrogen phosphate, said trace element is at least two kinds in zinc sulphate, potassium sulphate, potassium dihydrogen phosphate, borax, the ammonium molybdate, said auxin is α-Nai Yisuanna or heteroauxin, said colloid dispersant is the polymer of polyvinyl acetate and polyvinyl alcohol, and its content adopts following percentage by weight when selecting above-mentioned each material for use:
Tpn 0.3-0.35
Carbendazim 1.0-1.5
The red 0.25-0.3 of furans
Triazolone 1.25-1.5

Surplus is a water.
This technology is in use planted the interior super absorbent resin of clothing and can be absorbed moisture content on every side in a large number, becomes " the little reservoir of soil ", after this slowly disengages, and has strengthened crop drought control and drought resistance ability widely.Plant the agricultural chemicals in the clothing, little fertilizer, plant growing simultaneously and swash growth and the prevention and elimination of disease and pests ability that compositions such as rope have promoted crop effectively.
Because the super absorbent resin that above-mentioned technology adopted is in main chemical reactions after the manufactured goods of granulation, oven dry, pulverizing, in the preparation of seed coating medicine, need under hot conditions, to be reduced into liquid state, composite with other effective ingredients again, therefore this technology has the following disadvantages: at first in a series of physical refining processes that back segment adopted of preparation process of super absorbent resin, not only equipment investment is big, and labour intensity is high and influence product quality---make its water absorbent rate reduction; Secondly, in seed coating medicine composite, because super absorbent resin will be reduced into liquid state (pasty state) under hot conditions, and the temperature-fall period after its reduction is slow, so the quality to other effective ingredients of seed coating medicine such as agricultural chemicals, plant growth promoter, trace element etc. will cause remarkable reduction in practice, simultaneously, intensification in the reduction process and cooling also cause the raising of cost.
The deficiency of above-mentioned technology is that also the consumption of super absorbent resin is higher, thereby the gas permeability of seed is had certain influence.The consumption of part agricultural chemicals and trace element also has in addition needs to adjust part.
The objective of the invention is the above-mentioned not enough compound proportion of adjusting effective ingredient in the seed coating medicine, and improve complex process in the hope of further improving effect of increasing production and significantly reducing composite cost at prior art.
Drought-resistant seed compound coating agent provided by the present invention, contain certain proportion agricultural chemicals, trace element, auxin, colloid dispersant, super absorbent resin and water, it is characterized in that: the content of super absorbent resin is 1.8%-2.8% (percentage by weight).
The employed super absorbent resin of the composite above-mentioned seed coating medicine of the present invention is that aqueous dispersion is made (by weight percentage) by following material: acrylic acid 23.26-33.53, sodium hydroxide 11.53-15.27, methene base bisacrylamide 0.0083-0.017, Si Ban-600.0333-0.0415, ammonium persulfate 0.0332-0.0415, anhydrous sodium sulfite 0.0332-0.0415 contains gasoline 1-1.53 simultaneously, and surplus is a water.
A kind of embodiment of above-mentioned seed coating medicine is: contain (percentage by weight) super absorbent resin 1.8-2.8, triazolone 1.25-1.3, phosfolan_methyl 1.05-1.25, zinc sulphate 0.18-0.23, potassium sulphate 0.2-0.25, α-Nai Yisuanna 0.001-0.01, the polymer 0.1-0.15 of ETHYL CYANOACRYLATE and vinyl acetate, surplus is a water.
Second kind of embodiment of above-mentioned seed coating medicine contains (percentage by weight) super absorbent resin 1.8-2.6, tpn 0.3-0.35, Isofenphos methyl 1.0-1.5, zinc sulphate 0.18-0.23, potassium sulphate 0.2-0.25, α-Nai Yisuanna 0.005-0.01, the polymer 0.1-0.17 of ETHYL CYANOACRYLATE and vinyl acetate, surplus is a water.
The third embodiment of above-mentioned seed coating medicine contains (percentage by weight) super absorbent resin 1.6-2.4, carbendazim 1.0-1.5, the red 2.8-4.8 of furans, potassium dihydrogen phosphate 0.08-0.13, borax 0.08-0.13, heteroauxin 0.001-0.01, the polymer 0.15-0.2 of polyvinyl acetate and polyvinyl alcohol, surplus is a water.
