Problems solved by technology

There is a problem of inaccurate measurement of water preparations. Since naphthaleneacetic acid is a highly active plant growth regulator, inaccurate measurement can easily cause phytotoxicity; powders are easy to drift due to small particles, which will bring harm to the operator and the surrounding environment during production and use. many adverse effects

Abstract

The invention discloses naphthylacetic acid and naphthylacetic acid saline dispersible granules / or tablets and a preparation method thereof, wherein the naphthylacetic acid and naphthylacetic acid saline dispersible granules / or tablets comprise the following raw materials by mass percent: 0.1-90% of naphthylacetic acid and naphthylacetic acid salt, 0.5-15% of dispersant, 0.5-8% of wetting agent, 0-12% of disintegrating agent, 0-10% of binding agent and balance of padding. The preparation method is as follows: mixing the raw materials for forming the naphthylacetic acid and naphthylacetic acid saline dispersible granules / or tablets; after the naphthylacetic acid and naphthylacetic acid saline dispersible granules / or tablets are smashed by ultra-micro flow, pelleting, drying, finishing granules / tabletting, precisely selecting, detecting and obtaining the naphthylacetic acid and naphthylacetic acid saline dispersible granules / or tablets. The naphthylacetic acid and naphthylacetic acid saline dispersible granules / or tablets provided in the invention are safe for environment, people and livestock and other beneficial organisms, not easy to generate phytotoxicity, accurately measured and convenient to use and have quick disintegrating speed; and with better storage stability and simple preparation technology, the naphthylacetic acid and naphthylacetic acid saline dispersible granules / or tablets are suitable for industrial production and agricultural big area promotion.

Description

Technical field: [0001] The invention relates to a water-dispersible granule / or tablet of a plant growth regulator and a preparation method thereof, in particular to a water-dispersible granule / or tablet of naphthaleneacetic acid and naphthalene acetate and a preparation method thereof. Background technique: [0002] Naphthaleneacetic acid is a broad-spectrum plant growth regulator, which can promote cell division and expansion, induce the formation of adventitious roots, increase fruit setting, prevent fruit drop, and change the ratio of female and male flowers. It can enter the plant through the tender epidermis of leaves and branches, and the seeds are transported to the whole plant along with the nutrient flow. [0003] Scope of application Naphthaleneacetic acid is used in cereal crops to increase tillering, spike rate and thousand-grain weight; naphthaleneacetic acid is used in cotton to reduce bud shedding, increase peach weight and improve quality. Naphthaleneacetic...
