Description
Technical field
The present invention relates to a kind of be used to kill harmful molluscan fertilizer granules of paddy rice and manufacture method thereof.
Background technology
On agricultural, the snail of the farm crop of will causing harm (being commonly called as snail, non-irrigated spiral shell), slug (being commonly called as slug, slug), river snail (being commonly called as spiral shell), oncomelania (being bilharzial vector) etc. are referred to as harmful mollusk.The harmful mollusk of paddy rice of causing harm mainly is snail and Fushou spiral shell etc., the period of mainly causing harm be rice transplanting to tillering the Sheng phase, it is stung and cuts paddy rice master tiller and effective tillering, the lighter causes the disconnected ridge that is short of seedling, large stretch of paddy rice is ruined when serious, and especially spring and summer and autumn and winter weather are rainy, and it is heavier to cause harm when moist.
At present, be used for control harmful molluscan agricultural chemicals in rice field in the production and mainly contain the niclosamide ethanolamine salt, also have niclosamide, the methaldehyde and methiocarb etc.
Niclosamide ethanolamine salt (niclosamide ethanolamine) is a kind of invertebrate poison with stomach poison function, to spiral shell ovum, schistosomulum etc., stronger killing action is arranged, and is low to the person poultry toxicity, to crop safety.Can effectively prevent and treat harmful mollusks such as snail, slug, Fushou spiral shell.
In traditional agriculture production technology, applying fertilizer and above-mentioned sterilant separate, and twice or repeatedly use the way of above-mentioned sterilant and fertilizer, have increased peasant's labour intensity and work number of times, unfavorable agricultural development.The fertilizer granules applied once can be finished fertilising simultaneously and killed the mollusk two procedures, and the situation of having avoided dispenser in the past and fertilising not to take into account is saved time with artificial, has improved production efficiency.
The niclosamide ethanolamine salt combined with fertilizer make fertilizer granules and use still unmanned report.
Summary of the invention
Technical problem to be solved: the present invention is directed to the prior art deficiency provides a kind of niclosamide ethanolamine salt to combine with the science of fertilizer and a kind of fertilizer granules of developing, but applied once can apply fertilizer and the kill harmful mollusk in agriculture production, has overcome that user under the prior art condition wants twice or the way of use of insecticide and fertilizer repeatedly.
Technical scheme: fertilizer granules of the present invention is made up of following raw material: niclosamide ethanolamine salt, carrier fertilizer, sustained release dosage, attractive substance, dispersing auxiliary, filler; In the fertilizer granules gross weight, wherein:
Niclosamide ethanolamine salt 0.1%～10%, carrier fertilizer 30%～60%, dispersing auxiliary content 0.5%～3%, sustained release dosage 0.1%～2%, attractive substance content 0.1%～5%, all the other are filler.
Described fertilizer granules, wherein carrier fertilizer is the mixture of ammonium chloride, ammonium sulfate, urea, Repone K, vitriolate of tartar, monoammonium phosphate, Zinc Sulphate Monohydrate, boron, its N element nutrient content is 5%～25% of a fertilizer granules gross weight, the P constituent content is 1%～10% of a fertilizer granules gross weight, the K constituent content is 1%～10% of a fertilizer granules gross weight, zinc element content is 0.5%～2% of fertilizer granules gross weight, and boron content is 0.5%～2% of a fertilizer granules gross weight.
Described fertilizer granules, sustained release dosage are polyvinyl alcohol or gum arabic, and attractive substance is vegetable oil residue or soya-bean cake slag or peanut dregs, and dispersing auxiliary is W-Gum or sweet potato starch, and filler is a kaolin.
The concrete preparation method of fertilizer granules of the present invention is: the former medicine of 0.1%～10% niclosamide ethanolamine salt, 0.5%～3% dispersing auxiliary, 0.1%～2% sustained release dosage, 0.1%～5% attractive substance, 30%～60% carrier fertilizer and filler are mixed in airtight stirred pot, the granulation of coating method, under 110 ℃～120 ℃ conditions, be dried to the particle water content less than 3%, screening (size range 2000um～4000um), through after the assay was approved, promptly obtain required fertilizer granules.The powder sieving thing is back to stirred pot after crushed to be mixed again.Unacceptable product is back to stirred pot after the check analysis reason mixes again.Mix and adopt the method for fractional steps, the lower starting material of component concentration mix earlier the dispersing auxiliary of certain mass or filler again with other mixing of materials, to guarantee the homogeneity of product content, drying temperature is at 110 ℃～120 ℃, the variation of strict controlled temperature and fluctuation are in order to avoid the decomposition and the loss of agricultural chemicals, fertilizer composition.
The present invention has following unusual effect:
A kind of harmful molluscan fertilizer granules of paddy rice that is used to kill of the present invention combines a kind of fertilizer granules of developing by insecticide ingredient niclosamide ethanolamine salt with the science of fertilizer, alleviated peasant's labour intensity and work number of times.This product adopts current up-to-date slow release method to guarantee that effectively the science of agricultural chemicals, fertilizer discharges, prolong the lasting period of product, guarantee desinsection, fertilising double effects, add special attractive substance and give full play to product performance, improve drug effect and agricultural chemicals utilization ratio, reduce the waste of agricultural chemicals, fertilizer.Therefore this technology to effective, science, make rational use of resources, the protection environment has great significance, and the agricultural input that reduces the user and the increasing both production and income of agricultural are also played positive pushing effect.
Fertilizer granules of the present invention all has good prevention effect to the harmful mollusk of paddy rice as snail, slug, river snail, oncomelania etc., both can be used as the molluscan sterilant of paddy rice kill harmful, can also play the effect of fertilising volume increase.
In order better to verify practical application effect of the present invention, the field control effectiveness test of fertilizer granules of the present invention is described with example below, examine through The Institute for the Control of Agrochemicals of the Ministry of Agriculture,PRC, be arranged in the agriculture chemical examination institution, Guangdong Province, Institute of Plant Protection, academy of agricultural sciences, Hunan Province, Institute of Plant Protection, academy of agricultural sciences, Fujian Province, the agriculture chemical examination institution, Guangxi has carried out field control effectiveness test in four ground, is summarized as follows.
