Abstract
The invention discloses a kind of fertilizer granules of preventing and kill off paddy field weed and preparation method thereof. Herbicide fertilizer granules active component of the present invention is penoxsuam and bensulfuron-methyl, in granule gross weight, wherein: penoxsuam 0.01%～10%, bensulfuron-methyl 0.01%～10%, fertilizer 10%～60%, sustained release agent 0.1%～2%, binding agent 0.1%～10%, coating agent 0.1%～1%, all the other are filler. By above-mentioned material mix in proportion, the granulation of coating method, oven dry, screening, make fertilizer granules of the present invention. The existing weeding effect of fertilizer granules provided by the invention applied once in Rice Production, has again fertilising effect, has overcome under prior art condition and has needed twice or twice above way that uses herbicide and fertilizer.
Description
Technical field
The present invention relates to a kind of fertilizer granules of preventing and kill off paddy field weed and preparation method thereof.
Background technology
Penoxsuam, structural formula:
English name: penoxsulam, chemical name: 2-(2,2-difluoro ethoxy)-N-(5,8-dimethoxy (1,2,4) threeAzoles-(1,5-C) pyrimidine-2-base)-6-trifluoromethyl-benzene sulfanilamide (SN), the mechanism of action: medicine is inhaled via grass cutting blade, sheath portion or rootReceive, conduct to separate living tissue, cause weed growth to stop, yellow, then dead. Grassy weed, nutgrass flatsedge and broadleaved herb are hadGood preventive effect.
Bensulfuron-methyl, structural formula:
English name: bensulfuron-methyl, chemical name: α-{ [(4,6-dimethoxypyridin-α-yl) aminoCarbonylamino] sulfonyl methyl } methyl benzoate. Bensulfuron-methyl is selective inner-adsorption conduction-type herbicide, and active ingredient can beDiffusion rapidly in water, for weeds root and blade absorb the each portion of weeds that transfers to, hindered aminoacid, lysine, isoleucineBiosynthesis, stops division and the growth of cell. Susceptible weeds GF is obstructed, and tender tissue turns to be yellow too early and suppresses the life of leaf portionLong, hinder root growth and necrosis.
Existing penoxsuam, bensulfuron-methyl operation technique are to be prepared into oil-suspending agent, wettable powder, granule, waterDispersible granule, granulae effervescentes etc.
The inventor, to penoxsuam, bensulfuron-methyl, fertilizer further investigation, by its combination, is prepared into fertilizer granules,Complete weeding and the two procedures of topdressing simultaneously, avoided dispenser in the past and the situation about can not take into account of topdressing, save time and manually,Improve production efficiency.
The combination of penoxsuam and bensulfuron-methyl and Fertilizer combination are made to fertilizer granules and application there is no people's report.
Summary of the invention
Technical problem to be solved: the present invention is directed to prior art deficiency a kind of penoxsuam, the phonetic sulphur of benzyl are providedThe grand fertilizer granules being combined into fertilizer science, in agricultural production, applied once not only can be prevented and kill off paddy field weed but also can chase afterFertilizer, has overcome under prior art condition and has wanted twice or twice above way that uses herbicide and fertilizer.
The present invention also provides the preparation method of above-mentioned fertilizer granules.
Technical scheme: a kind of fertilizer granules of preventing and kill off paddy field weed, herbicidal active component is by penoxsuam and benzylSulfometuron Methyl composition. In fertilizer granules gross weight, wherein: penoxsuam 0.01%～10%, bensulfuron-methyl 0.01%～10%,Fertilizer 10%～60%, sustained release agent 0.1%～2%, binding agent 0.1%～10%, coating agent 0.1～1%, all the other are filler.
Described fertilizer is to obtain one or more in ammonium chloride, ammonium sulfate, urea, potassium chloride, potassium sulfate, MAP etc.Combination, its N element nutrient content is 5%～30% of fertilizer granules gross weight, P constituent content is fertilizer granules gross weight0～20%, K constituent content is 0～20% of fertilizer granules gross weight, and micronutrient levels is fertilizer granules gross weight0.01～5%。
Described trace element is one or more groups of the required elements of plant growth such as zinc, boron, calcium, magnesium, manganese, copper, molybdenumClose.
Described sustained release agent is polyvinyl alcohol or Arabic gum.
Described binding agent is attapulgite, paraffin, rosin, gelatinized starch, xanthans, carboxymethyl cellulose, carboxyethylOne or more combination in cellulose, methylcellulose.
Described coating agent is polyvinyl alcohol, polyvinylpyrrolidone, mylar, acrylic acid synthetic polymer, propyleneOne or more combination in acid resin film forming agent, butadiene resin film forming agent, polyurethane finishing agent, cellulose nitrate film forming agent.
Described filler is a kind of or several in kaolin, diatomite, white carbon, starch, stone flour, quartz sand, brick slag etc.Plant combination.
A kind of fertilizer granules preparation method who prevents and treats paddy field weed: 0.01%～10% penoxsuam, 0.01%～10% bensulfuron-methyl, 10%～60% fertilizer, 0.1%～2% sustained release agent, 0.1%～10% binding agent, 0.1%～0.5% coating agent, surplusAfter filler mixes in airtight agitator tank, add in Granulation Equipments and carry out the granulation of coating method, 80 DEG C～100 DEG C conditionsUnder be dried to particle water content and be less than 3%, screening, particle size range 2000um～4000um, through after the assay was approved, obtains requiredFertilizer granules. Powder sieving thing is back to agitator tank after crushed to be mixed again; Defective work is after check analysis reasonBe back to agitator tank and again mix, mix and adopt the method for fractional steps, the raw material that constituent content is lower first mix the fertilizer of certain massOr filler again with other mixing of materials, to guarantee the uniformity of product content, baking temperature is at 80 DEG C～100 DEG C, strictly controlsThe variation of temperature and fluctuation, in order to avoid decomposition and the loss of agricultural chemicals, fertilizer composition.
Compared with prior art, the present invention has following remarkable result.
A kind of fertilizer granules of preventing and treating paddy field weed of the present invention, by weeding active ingredient penoxsuam, benzylA kind of fertilizer granules that the exploitations of Sulfometuron Methyl and Fertilizer combination form, the dual work that applied once can reach weeding and topdressWith, alleviate peasant's labour intensity and work number of times, save time and manually, improved production efficiency.
The present invention adopts modern mechanical processing technology, and active ingredient is evenly distributed in product, and preparation method easily graspsDo. Product directly spreads fertilizer over the fields and can be distributed in uniformly field, is conducive to active ingredient and is inhaled by paddy rice by the absorption of weeds and fertilizerReceive, having overcome prior art needs twice or twice above way that uses herbicide and fertilizer.
Adopt slow release method, effectively ensure the slow release of agricultural chemicals, fertilizer, extend the lasting period of product, improve drug effectWith agricultural chemicals utilization rate, reduce the waste of agricultural chemicals, fertilizer, guarantee control of insect, double effects topdresses.
Avoid the existing operation technique of agricultural chemicals to be watered spraying or artificial pesticide-clay mixture method causes the contaminated environment phenomenons such as drift.
Fertilizer granules product, with respect to twice use of agricultural chemicals and fertilizer, has been saved helping in a set of packing material and agricultural chemicalsAgent cost and circulation cost.
A kind of fertilizer granules of preventing and treating paddy field weed of the present invention is used for preventing and kill off paddy field weed and has good control effectReally.
A kind of fertilizer granules of preventing and treating paddy field weed of the present invention has to be used conveniently, and weeding, the double effects that topdresses, carryHigh effect, the advantages such as environmental protection.
