Embodiment 1

[0043] Example 1: Cartap content 0.8%; macronutrient N content 12% (from urea), P content 5% (from monoammonium phosphate), K content 5% (from potassium sulfate) in fertilizer ingredients, trace amount in fertilizer ingredients Elemental zinc content 0.2% (from zinc sulfate monohydrate), boron content 0.1% (from borax), magnesium content 0.2% (from magnesium sulfate); slow-release agent polyvinyl alcohol content 0.1%, binder methyl cellulose 0.5 %, the coating agent polyester resin is 0.3%, and the balance is diatomaceous earth as a filler. According to the preparation method of medicinal fertilizer granules of the present invention, 0.8% cartap medicinal fertilizer granules are obtained. Sprinkle at the peak hatching stage of rice stem borer and rice leaf roller, 8-10kg per mu, can achieve ideal control effect, and at the same time play the role of topdressing.

Embodiment 2

[0044] Embodiment 2; cartap content 2%; macroelement N content 15% (from urea), P content 8% (from monoammonium phosphate), K content 10% (from potassium sulfate) in the fertilizer composition, trace amount in the fertilizer composition Elemental zinc content 0.3% (from zinc sulfate monohydrate), boron content 0.2% (from borax), magnesium content 0.1% (from magnesium sulfate); slow release agent gum arabic content 0.2%, binder attapulgite 0.6%, The coating agent polyvinyl alcohol is 0.5%, and the balance is filler kaolin. According to the preparation method of medicinal fertilizer granules of the present invention, 2% cartap medicinal fertilizer granules are obtained. It can be applied at the peak hatching stage of the eggs of rice stem borer and rice leaf roller, and the application of 3-4kg per mu can achieve ideal control effect, and at the same time play the role of topdressing.

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 [0001] The invention relates to a medicinal fertilizer technology for paddy fields, in particular to a medicinal fertilizer granule containing an insecticide and a compound fertilizer, and a preparation method and application thereof. Background technique [0002] Cartap, chemical name: 1,3-bis-(carbamoylthio)-2-dimethylaminopropane, English name: cartap, a derivative of nereistoxin, has a wide insecticidal spectrum and can be used to control Lepidoptera, Coleoptera, Hemiptera, Diptera and other pests and nematodes. Little effect on predatory mites. Its toxicological mechanism is to block the impulse transmission of nerve cell junctions in the central nervous system, paralyzing insects. [0003] In the traditional pesticide application technology, the formulations of cartap include powder, wettable powder, granule, water, and suspension. Use is separate. [0004] The present inventor studies the dosage form and application of cartap in depth, combines it ...
