Problems solved by technology

But in actual production and application, above-mentioned technology has the defect and deficiency of following two respects, and the one, the floating carrier with medicine is that pesticide is added a small amount of water to dilute, sprays and mixes on the grass powder that corn stalks are broken into and makes, and with dispensing It is better to use it as you like. It can be seen that this technology is not conducive to industrialized production, and it is easy to cause unstable pesticide content in the paddy field, and local drug effects are different when used; Plant growth regulator, while promoting the growth of rice, will further reduce the labor intensity caused by single application

Abstract

The invention discloses paddy field floating granule as well as a preparation method and application of the paddy field floating granule. A processing preparation of slow-released floating granule is adopted by utilizing a modern mechanized processing process; the paddy field floating granule is prepared by taking a paddy rice striped rice borer prevention and treatment agent, fertilizer and a plant growth regulator as main effective components, adding auxiliary materials including a water-surface floating carrier, a binding agent, a dispersant, a slow releasing agent and the like, and compounding. In a utilization process of the paddy field floating granule provided by the invention, soil does not need to be blended and the paddy field floating granule is directly broadcasted; a medicament can be slowly released, is uniformly distributed in a paddy field and has the effects of killing striped rice borers, strengthening seedlings, and adjusting the growth of paddy rice; the paddy field floating granule has the effects of increasing the yield and improving the quality of the paddy rice, and reducing the labor intensity caused by independent application of the fertilizer and the plant growth regulator.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to paddy field floating granules and a preparation method and application thereof. Background technique [0002] The current pesticide application technology is mainly spraying with water or mixing with sand or soil, which not only causes the waste of pesticides because they fail to hit biological targets, but also has high labor intensity and low work efficiency. Therefore, how to accurately deliver pesticides to biological targets to reduce the amount of pesticides used, reduce environmental pollution, and reduce labor intensity is a prominent problem that needs to be solved in crop production. [0003] The existing technology "Research on the Prevention and Control of Rice Borer with Drug-carrying Floating Carrier" uses a drug-carrying floating carrier to apply pesticides on the water surface. Under the capillary action of the gap between them, it rises above the harmed part of...
