Abstract
The invention discloses a special seed coating agent for micro-endosperm corns, which is a suspending agent shape seed coating agent consisting of imidacloprid, carbendazim, ethrel, IBA, 6-BA, cane sugar, potassium dihydrogen phosphate, potassium nitrate and/or ammonium dihydrogen phosphate, magnesium sulplate, microbiological fertilizer, film-forming agent, non-anionic emulsifier, anionic emulsifier, sodium benzoate, ethylene glycol, n-octyl alcohol, acid scarlet or safranine T and the rest of water. The special seed coating agent for micro-endosperm corns provides a plant growth regulator, thereby quickening the activation of the seeds and promoting the sprouting of the seeds; simultaneously, the special seed coating agent provides various nutritive elements when the root systems of the seeds are not formed, therefore, the metabolism of the seeds is accelerated so that the seedlings emerge ahead of time, and the invalid consumption of the seeds in the soil is reduced; the seeds in the soil and after emergence of seedlings are respectively protected with pesticide, thereby preventing the seeds form being harmed from the diseases and the insects; and the seed coating agent is simultaneously suitable for other corn varieties, the emergence of seedlings of which is affected due to insufficient nutrition or difficult root initiation.
Description
Technical field
The present invention relates to the agent of a kind of plant species clothing, particularly a kind of seed-dressing agent special for micro-endosperm corn of preventing and treating seedling stage diseases and pests and promoting the corn of the root of hair and the difficulty of emerging.
Background technology
Special is the direction of 21 century corn development with corn; Micro-endosperm corn is to adapt to the needs that corn is developed with corn to the spy by conventional corn; Novel super-high oil corn germplasm by professor Wu Zikai of agricultural college of Guangxi University cultivation; It is characterized in that oil content is high, majority has reached more than 20%, and part surpasses 30%.As everyone knows; Corn oil is the higher high-quality edible oil of unsaturated fatty acid content; Edible oil in the U.S. existing 40% is a corn oil; Because of corn is high than other economic crops and cereal crops output, while corn oil quality is more excellent, high oil corn will become one of main direction of 21 century corn development, and micro-endosperm corn is that the needs seed selection that adapts to the corn development forms.But micro-endosperm corn has two shortcomings, and one for yielding poorly; The 2nd, emergence rate is low, is merely about 30～60%, and its emergence rate causes increase and the field of sowing quantity to be short of seedling in a large number and influences output less than 40% when meeting adverse circumstance.Many researchs show; Seed treatment can improve germination vigor, the germination rate of seed; Thereby improve field emergence etc.; Wherein seed pelleting is at present both at home and abroad just at the seed processing technology of research and development, is control crops seedling stage diseases and pests and the easiest, the economy that improve crop yield also are technical measures the most safely and effectively.Nowadays existing many type kind clothing agent are sold on the market, but since mostly several clothing agent cause lacking endosperm the micro-endosperm corn seed of seed sprouting phase nutritional deficiency only to damage by disease and insect, be not very big to the facilitation of emerging; And because the micro-endosperm corn seed endosperm is few, embryo is because lacking the protection of endosperm very easily comes to harm, and present commercially available kind of clothing agent all has certain poisoning to it.Therefore, it is very necessary to develop a kind of kind clothing agent that can promote the micro-endosperm corn seed sprouting, and the present invention plants the clothing agent and adapts to these needs and develop.
Summary of the invention
, be intended to improve the emergence rate of micro-endosperm corn seed, solve the problem that runs in the production of micro-endosperm corn land for growing field crops through making the kind clothing agent of suitable micro-endosperm corn seed.
The technical scheme that the present invention solves the problems of the technologies described above is following:
The prescription of seed-dressing agent special for micro-endosperm corn; Be the suspending agent of being processed by the composition of following weight percentage: Imidacloprid 1～4%, carbendazim 1～4%, ethrel 0.02～0.1%, IBA 0.0005～0.0015%, 6-BA 0.0005～0.0015%, sucrose 1～4%, potassium dihydrogen phosphate 2～6%, potassium nitrate and/or ammonium dihydrogen phosphate (ADP) 2～6%, magnesium sulfate 1～3%, little fertile 0.1～0.4%, film forming agent 1～2%, non-, anion emulsifier 0.1～0.3%, sodium benzoate 0.2～0.5%, ethylene glycol 0.1～0.2%, n-octyl alcohol 0.2～1%, acid scarlet or sarranine premium T 0.5～1.5%, its surplus are that water is formed SC-like kind of clothing agent.
Above-mentioned film forming agent is sodium carboxymethylcellulose, extra large bath acid sodium, polyvinyl alcohol; Wherein: sodium carboxymethylcellulose can use as film forming agent separately or three kinds of film forming agents cooperations are used as film forming agent; Their weight ratio proportioning is a sodium carboxymethylcellulose: extra large bath acid sodium: polyvinyl alcohol=1～2: 0～2: 0～2, and best proportioning is 1: 2: 1.
Above-mentioned non-, anion emulsifier be in lauryl sodium sulfate, OP-emulsifier and the Tween-20 any two kinds with 1: 1 composition of weight ratio.
Above-mentioned little fertilizer and their weight percentage are: potassium chloride 0.03～0.09%, boric acid 0.012～0.036%, manganese sulfate monohydrate 0.012～0.036%, white vitriol 0.0022～0.0066%, cupric sulfate pentahydrate 0.00048～0.00144%, molybdic acid 0.00032～0.00096%, ferrous sulfate 0.06～0.18% and EDTA-2Na0.08～0.24%.
The preparation method of seed-dressing agent special for micro-endosperm corn fully reacts ferrous sulfate and EDTA-2Na huge legendary turtle and becomes molysite with 30% water boil of the water yield in kind of the clothing agent prescription, pours in the preparation kettle of sand mill; With 50% hot water dissolving of film forming agent, change in the preparation kettle of sand mill with the water yield in kind of the clothing agent prescription; Imidacloprid and carbendazim are added to 20% of the water yield in kind of the clothing agent prescription to be poured in the preparation kettle after the dissolving in the surfactant; Press formula rate to all the other components and add in the preparation kettle, with sand mill each composition is milled to about 5 microns, changing in the high-speed homogenization machine fully, homogenate is SC-like finished product.
The coating method of seed-dressing agent special for micro-endosperm corn is that kind of clothing agent is 1: 10～1: 30 with the seed weight ratio, and method is following:
1) with dressing machine dressing, concrete operations are operated according to dressing machine specification;
2) dressing by hand takes by weighing the seed of constant weight, places the container of lid, and than adding kind of a clothing agent, cover lid fully shakes up, and makes the surface of all seeds all wrap kind of a clothing agent by kind of clothing agent and seed weight.Be placed on aeration-drying place dry (about 4～6 hours) promptly can be used for the sowing.
Beneficial effect of the present invention is:
1. the agent of this kind clothing is primarily aimed at underfed seed design.Seed-dressing agent special for micro-endosperm corn of the present invention provides plant growth regulator, can accelerate the activation of seed, promotes seed germination; Simultaneously the seed root system also form in for it provides various nutritive elements, accelerate the metabolism of seed itself, seed is emerged in advance, the effective consumption of minimizing seed in soil; Seed all has agricultural chemicals protection in soil and after emerging, can make it avoid the harm of disease worm.
2. because prescription of the present invention contains the various trace elements of seed sprouting needs, contain the growth regulator that promotes the root system development, therefore, the present invention plants the clothing agent and is fit to other simultaneously owing to oligotrophy or the difficult corn variety of emerging that influences of root of hair.
