Description

Multifunctional coating agent for dry culturing straight seeding

Technical field:

The present invention relates to a kind of coating agent for seed, more particularly: be to mix the seed treatment of forming with compositions such as agriculture chemicals fungicide, insecticide, middle micronutrient element, polymer water-absorbent, seed oxygenate, soil conditioner, drought resistance agent, soil regulating acid agent, film forming agent and plant growth regulator.

Background technology:

Coating agent for seed is the seed treatment that rises the external seventies in 20th century, the beginning of the eighties, external seed coating medicine product begins to enter China market, China scientific research personnel also begins development simultaneously, to the nineties existing successful technology and product appear on the market, through this effort in several years, the seed coating medicine that China produces reaches or approaches advanced international standards on effective component content, and when compound preparation direction develops, take into account agronomy and local ecological characteristic, middle trace element and plant growth regulator etc. have been added, the special-purpose formulation that seed coating medicine is handled as seed pelleting, in China is a rising new product, it has the seed of increase volume, increase seed weight, the sick worm plague of rats of integrated control and nutritional deficiency disease, the effect that improves output and improvement crops quality is because the crop seeds volume is little, resistance is poor, subjects to the harm of damage by disease and insect.On producing, there are problems such as seeding quantity is big, seedling management is difficult, seedling quality is poor, cost input height.Therefore, many agricultural research units have dropped into a large amount of financial resources, human and material resources are developed many coating agent for seed products.As: " a kind of immersion-type multifunctional coating agent for rice seeds " of Hunan Agriculture University Paddy Research Institute's development (authorizing publication number CN1156213C), this product has mixed bactericide, insecticide, plant growth regulator and trace element etc., this class kind clothing agent product can make the seed volume enlarge, and the physical property state neat and consistent of the surface of the seed, has good adaptability, can carry out precise sowing, and have certain disease resistance.But also exist obvious defects: the one, can not have the function of retaining, water conservation, seedling-protection.The 2nd, can not be in wetland or reason such as rainfall make soil surface form native film, make oxygen deficiency in the soil, can not the oxygen supply ventilation cause crop seed to be choked to death, or percentage of seedgermination is reduced, seriously influenced seed sprouting.The 3rd, equipment investment is bigger, produces complicatedly, and cracky leaks in transportation, the storage process, to drawbacks such as safety are unfavorable.

The objective of the invention is to avoid above-mentioned weak point of the prior art, and a kind of emergence rate that can obviously improve seed is proposed, have retaining, water conservation, water supply and enhancing soil aeration oxygen supply, the height that reaches full stand, Qi Miao, strong sprout absorb water multi-functional seed coating medicine and manufacture craft.

Summary of the invention:

The present invention carries out by the following technical programs:

Be with powder raw materials such as fulvic acid, polymer water-absorbent, calper calcium peroxide, carbendazim, paclobutrazol, methyl, carbofuran, zinc sulphate, manganese sulphate, magnesium sulfate, ferrous sulfate, neutral siliceous fertilizer, concavo-convex fine clay, carboxymethyl celluloses, and formulated in proportion, each composition proportion is: (percentage by weight)

Fulvic acid 0.3%～1.0%

Polymer water-absorbent 5%～15%

Calper calcium peroxide 3%～10%

Carbendazim 0.5%～1.5%

Paclobutrazol 0.01%～0.09%

Methyl 0.005%～0.09%

Carbofuran 0.5%～1.5%

Zinc sulphate 0.2%～1%

Manganese sulphate 0.2%～0.5%

Magnesium sulfate 2%～10%

Ferrous sulfate 0.2%～1%

Neutral siliceous fertilizer 3%～10%

Concavo-convex fine clay 50%～80%

Carboxymethyl cellulose 2%～8%

Contain the various plants active group with the fulvic acid in the above-mentioned raw materials, as carboxyl (COOH), phenol carboxyl (C _Virtue-OH), quinonyl etc., this material has resistance inhibitor action to the growth oxidase that destroys growth hormone, and make growth hormone play obvious effect, improve crop self drought-resistant ability, this material also can be used as the interior metabolic process of acceptor involved in plant body of hydrogen, promote synthetic (especially under the condition of anoxic) of adenosine triphosphate (ATP), play a part the crop respiratory catalyst as the source of supply of polyhydric phenols at the plant growing initial stage, from and demonstrate waterlogging-resistant function.Polymer water-absorbent, in soil, absorbed the micro-moisture in the soil, around seed, form " the standby storehouse of retaining ", " the standby storehouse of fertile medicine " simultaneously, can slow down gravity dehydration and expansion dehydration in the nursery soil effectively, increased around the seed and the water content of seedling root soil, and can make the slow oxygen supply of calper calcium peroxide, strengthened the air capacity of soils and the water penetration of soil, can reduce seeding and seedling raising water number of times and water consumption significantly, promote early to emerge, have more seedling, go out full stand and educate strong sprout.Because the water sorption of polymer water-absorbent; the agriculture chemicals fungicide carbendazim in interior absorption and load; the property of medicine that the insecticide carbofuran slowly discharges; become crop disease prevention and control the protection barrier of worm; make seed prevent the invasion and attack of germ in the soil; when coming up; medicament slowly discharges in " the standby storehouse of fertile medicine "; passed to the position, ground of not dispenser after the seedling absorption; continued the preventing disease pest control effect; middle micronutrient element fertiliser containing magnesium; zinc fertilizer; the slow release of manganese fertilizer and iron fertilizer; eliminated the nutritional deficiency disease in the soil; simultaneously as soil conditioner; the soil regulating acid agent; decompose the salinity in the soil, prevented the generation of pernicious gases such as the increase of the salinity in the soil and hydrogen sulphide.And can participate in the synthetic of growth hormone heteroauxin in the crop seedling body, make seedling at wet weather, low temperature continuously, lack under the situation of illumination, promote the well developed root system of seedling, increased cold-resistant, drought resisting, degeneration-resistant ability, prevent the generation of Huang (in vain) change disease.In addition, because the effect of plant growth regulator methyl, paclobutrazol, siliceous fertilizer and carboxymethyl cellulose, improved soil aggregate, strengthened the disease resistance of crop, improved fertilizer utilization ratio, reached nutrition, acid adjustment, short root, increase tiller, diseases prevention, control worm, multiple efficacies such as seedling are become strong in control.

The live multi-functional seed coating medicine of early childbirth according to the present invention, carried out field multiple spot comparative trial in continuous 3 years, area reaches more than 30,000 mu, after using, can improve emergence rate 15-20%, emergence rate reaches 96%, paddy rice, wheat all increase production 10-15%, corn on average increases production 18.6%, and the mythimna separata rate that causes harm reduces by 14%, after the cotton seeds Cotton seeds, can prevent and treat soil insect, seedling stage aphid, damping off, anthracnose effectively, help early emerging, full stand, strong sprout, improved seeding quality, reached the purpose of increasing both production and income.

Advantage of the present invention: raw material is easily purchased, consumption is few, cost is low, repayment is high, use conveniently, be convenient to characteristics such as transportation.

Using method of the present invention: after crop seed was soaked in water 0.5-24 hour, taking out to drench goes excessive moisture to place container, then seed coating medicine is slowly added, fully stirs (stir and can add 1.5% carboxymethyl cellulose aqueous solution in right amount midway), until crop seed all by the group's of rolling dressing.
