specific Embodiment

[0036] Specific embodiment, a kind of plant growth bactericidal accelerator, is the nano-TiO of 1 / 3rd by component ratio 21 / 3 of chitosan and 1 / 3 of slow-release coating film, the plant growth bactericidal accelerator is an accelerator in the form of a slow-release agent.

[0037] The nano-TiO 2 Anatase nano-TiO produced for Hebei Meisen Titanium Dioxide Co., Ltd. 2 , and TiO 2 The content is greater than 99.9%.

[0038] The chitosan is the chitosan produced by Qingdao Ocean New Material Technology Co., Ltd. with a deacetylation degree of 92.76%.

[0039] A kind of preparation technology of plant growth bactericidal accelerator is characterized in that comprising the following steps:

[0040] A. Preparation of modified nano-TiO 2 powder, including:

[0041] A1, preparing the solution, weighing 10 parts by mass of nano-TiO 2 Add it to 140 parts of water, then drop in citric acid until the pH value is adjusted to 5, then add 1.5 parts of sodium laurate, and stir at 40°C f...

Abstract

The invention relates to a plant growth sterilization accelerator and a preparation process for the same. The plant growth sterilization accelerator consists of 30+ / -3 percent of TiO2, 35+ / -3 percent of chitosan, 4+ / -3 percent of emulsifier OP-10, 9+ / -3 percent of sodium phosphite solution and 22+ / -3 percent of citric acid. The preparation process comprises the steps of preparing modified TiO2 nanopowder, preparing nanometer titanium dioxide / chitosan treating fluid, preparing a sustained-release coating film, and performing mixing while stirring to prepare the plant growth sterilization accelerator. The plant growth sterilization accelerator and the preparation process have the beneficial effects that the sustained-release coating film contains TiO2, chitosan, the emulsifier, the sodium phosphite solution and the citric acid, so that the effects of the accelerator can be retarded, the efficacy of the accelerator sprayed on the leaves of plants can last long and is persistent, and the production cost of crops is reduced.

Description

technical field [0001] The invention relates to the technical field of photocatalysts, in particular to a plant growth and sterilization accelerator and a preparation process thereof. Background technique [0002] Food is the most important thing for the people, but the first element of human survival - food, is facing a situation of increasing shortage. And how to improve the photosynthesis of plants is the most direct and effective way to solve the problem of accelerating plant growth and increasing yield. According to the mechanism of plant photosynthesis, it is found in the research that photocatalyst and dark catalyst can be used, and spraying on the leaves of plants can improve the utilization rate of light and make photosynthesis more active, even in the rainy season when the amount of sunlight is insufficient (because the absorption is Ultraviolet rays) also have a good promoting effect. It is different from the existing technology of using chemical fertilizers and...
