Abstract
The invention discloses cartap fertilizer granules and a preparation method thereof. The cartap fertilizer granules comprise a pesticide, fertilizer, a slow release formulation, a bonding agent, a film coating agent and filler, and are characterized in that the pesticide is cartap and the fertilizer contains nitrogen, phosphorus, potassium, zinc, boron and magnesium. The invention further discloses the preparation method for the cartap fertilizer granules. The cartap fertilizer granules are applied to paddy rice, so that not only be the fertilizer can added but also rice-stem borers and rice leaf folders can be killed, the working intensity and the working frequency of farmers are reduced, and the shortcoming that the pesticide and the fertilizer need to be used for two or more times by a user under the existing technical conditions is overcome.
Description
Technical field
The present invention relates to the medicine fertilizer technology for rice terrace, specifically relate to a kind of fertilizer granules containing sterilant and compound manure, and its preparation method and application.
Background technology
Cartap, chemical name: 1,3-bis--(carbamyl sulphur)-2-dimethylaminopropanecompounds, English name: cartap, a kind of derivative of nereistoxin, insecticidal spectrum is wide, can be used for various pests and the nematodes such as control lepidopteran, Coleoptera, Hemiptera, Diptera.Little on predacious mites impact.Its toxicological mechanism is the transmission impulse action of blocking nerves cell contact in central nervous system, makes insect paralysis.
In traditional technique in using agriculture chemical, cartap formulation has pulvis, wettable powder, granule, aqua, suspension agent, and use the application method of this type of formulation mostly to be and be watered spraying or dispenser, cartap and Fertilizer application separate.
The present inventor is to the formulation of cartap and application further investigation, by itself and Fertilizer combination, be prepared into fertilizer granules, water prevention chilo suppressalis, Cnaphalocrocis medinali(rice leaf roller) can complete desinsection and two procedures of topdressing simultaneously, avoid dispenser in the past and situation about can not take into account of topdressing, save time and manually, improve production efficiency.
Cartap and Fertilizer combination are made cartap fertilizer granules and application thereof to there is no people and report.
Summary of the invention
Technical problem to be solved: the present invention is directed to prior art deficiency and provide the combination of sciences of a kind of cartap and fertilizer and the fertilizer granules developed, in agriculture production applied once both can water prevention chilo suppressalis, Cnaphalocrocis medinali(rice leaf roller), can topdress again, overcome user under prior art condition and want twice or the way of repeatedly use of insecticide and fertilizer.
Present invention also offers the preparation method of above-mentioned fertilizer granules.
Above-mentioned purpose of the present invention is achieved through the following technical solutions:
There is provided a kind of fertilizer granules, it is made up of agricultural chemical insecticide, fertilizer component, sustained release dosage, binding agent, coating agent and filler.Wherein, described agricultural chemical insecticide is cartap; Described fertilizer component comprises nitrogen, phosphorus, potassium, zinc, boron and magnesium elements.
The weight percent of each component is as follows: agricultural chemical insecticide: cartap 0.2% ~ 10%.
Fertilizer component: nitrogen element 5% ~ 30%, phosphoric 0% ~ 15%, potassium element 0% ~ 15%, zinc unit
Element 0.1% ~ 5%, boron 0.1% ~ 5%, magnesium elements 0.1% ~ 5%; Auxiliary agent: sustained release dosage 0.1% ~ 2%, binding agent 0.1% ~ 10%, coating agent 0.1% ~ 0.5%; Surplus is filler.
Described nitrogen element from urea, phosphoric from monoammonium phosphate, potassium element from potassium sulfate,
Zinc element is from Zinc Sulphate Monohydrate, and boron is from borax, and magnesium elements is from magnesium sulfate.
Described sustained release dosage is polyvinyl alcohol or gum arabic.
Described binding agent is the one or more combination in attapulgite, paraffin, rosin, pasted starch, xanthan gum, carboxymethyl cellulose, carboxyethyl cellulose, methylcellulose gum etc.
Described coating agent is the one or more combination in polyvinyl alcohol, polyvinylpyrrolidone, vibrin, vinylformic acid synthetic polymer, acrylic resin membrane-forming agent, butadiene resin membrane-forming agent, polyurethane finishing agent, cellulose nitrate membrane-forming agent etc.
Described filler is the one or more combination in kaolin, diatomite, white carbon black, Calcium hydrogen carbonate, starch, stone flour, quartz sand, brick slag etc.
The preparation method of described fertilizer granules is: the agricultural chemical insecticide of described ratio, fertilizer component, sustained release dosage, binding agent, coating agent and filler are mixed together granulation, prepares described fertilizer granules product finally by dry, film-coating technique technique.
In the preparation method of fertilizer granules preferably described further, mixing process adopts the method for fractional steps, to guarantee the homogeneity of product content, first mixes, then mixes with surplus stock with sustained release dosage, binding agent, coating agent by the former medicine of cartap.
In preferred preparation method, described drying temperature, at 110-120 DEG C, avoids decomposition and the loss of agricultural chemicals, fertilizer component by the change and fluctuation strictly controlling drying temperature.
Described fertilizer granules is applied to water prevention chilo suppressalis, Cnaphalocrocis medinali(rice leaf roller).
Compared with prior art, the present invention has following unusual effect.
Fertilizer granules of the present invention, formed by the combination of sciences exploitation of agricultural chemical insecticide composition cartap and fertilizer, applied once can reach desinsection and the dual function of topdressing, and alleviates labour intensity and the work number of times of peasant, save time and manually, improve production efficiency.
The present invention adopts modern mechanical complete processing, and effective constituent is evenly distributed in the product, and preparation method easily operates.Product in use need not be mixed soil or be watered spraying, directly spread fertilizer over the fields, medicament can be distributed in field uniformly, is more conducive to absorbing of effective constituent, overcomes the inconsistent phenomenon of drug effect that artificial pesticide-clay mixture method easily occurs in field, fertilizer efficiency and Spray Drift causes poisoning phenomenon.
Adopt slow release method, effectively ensure the science release of agricultural chemicals, fertilizer, guarantee desinsection, topdress double effects, extend the lasting period of product, improve drug effect and agricultural chemicals utilization ratio, reduce the waste of agricultural chemicals, fertilizer.
Fertilizer granules formulation of the present invention environmental protection, uses conveniently, safety, low toxicity, low risk.
In order to better verify practical application effect of the present invention, the field control effectiveness test effect of fertilizer granules of the present invention is described below with field efficacy example.
Reagent agent: (1) test medicine: 0.8% cartap fertilizer granules (embodiment 2).(2) medicament is contrasted: 4% cartap granular preparation.
Medicament using method: spread fertilizer over the fields in rice-stem borer, Cnaphalocrocis medinali(rice leaf roller) egg hatching phase of containing.
Controlling object: rice-stem borer, Cnaphalocrocis medinali(rice leaf roller).
Table 1, testing program.
Table 2,0.8% cartap fertilizer granules water prevention chilo suppressalis test-results.
Table 3,0.8% cartap fertilizer granules control Cnaphalocrocis medinali(rice leaf roller) test-results.
Table 4,0.8% cartap fertilizer granules are to increasing production of rice effect.
As can be seen from test-results table 2, table 3, table 4,0.8% cartap fertilizer granules mu 8 kilograms, 10 kilograms, 12 kilograms water prevention chilo suppressalis, Cnaphalocrocis medinali(rice leaf roller) excellent, same effective ingredient consumption 0.8% cartap fertilizer granules is more effective than 4% cartap fertilizer granules, and effect of increasing production is obvious.Poisoning, fertilizer damage phenomenon is found no in process of the test.
