specific Embodiment approach 1

[0010] Specific embodiment 1: The plant growth regulator containing nano-titanium dioxide in this embodiment is made of nano-titanium dioxide, adhesion agent, water, dispersant, penetrating agent and additives; wherein the weight ratio of nano-titanium dioxide, adhesion agent and water is 0.2-1 : 50: 100, the consumption of dispersant is 0.1%~0.5% of the mass of nano titanium dioxide, the consumption of penetrating agent is 0.1%~1% of the mass of nano titanium dioxide, and the weight ratio of additive to water is 0.01~1:100.

specific Embodiment approach 2

[0011] Embodiment 2: The difference between this embodiment and Embodiment 1 is that water is neutral. Others are the same as the first embodiment.

specific Embodiment approach 3

[0012] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the nano-titanium dioxide is anatase and / or rutile, and the particle size of the nano-titanium dioxide is 10-50 nm. Others are the same as the first or second embodiment.

[0013] In this embodiment, the nano-titanium dioxide is composed of two kinds of nano-titanium dioxide of anatase type and rutile type, and the ratio of anatase type and rutile type can be arbitrary.

Abstract

The invention discloses a plant growth regulator containing nanometer titanium dioxide and a preparation method thereof, relating to a plant growth regulator and a preparation method thereof. The invention solves the problems of low use density, low absorption and utilization ratio and poor adhesive force of nanometer titanium in the existing plant growth regulator containing nanometer titanium dioxide. The growth regulator is prepared from the nanometer titanium dioxide, adhesive, water, dispersing agent, penetrating agent and additive. The preparation method is as follows: sequentially adding the adhesive, the penetrating agent, the dispersing agent, the nanometer titanium dioxide and the additive in water; continuously stirring for 1-2 minutes to obtain the plant growth regulator containing the nanometer titanium dioxide. The plant growth regulator of the invention can accelerate plant growth and is used for crop increment.

Description

technical field [0001] The invention relates to a plant growth regulator and a preparation method thereof. Background technique [0002] The important role played by titanium on plant growth has been generally recognized by scientists from all over the world for many years. It can not only improve the photosynthesis efficiency of plants, but also improve nitrogenase, peroxidase, nitrate reductase, fructose 2,6 - Biphosphatase activity, and has hormone-like effects. It is scientifically found that the titanium content in the body of plants should be above 20ppm for normal growth. Sampling and analysis of different soil types in my country by researchers shows that the total titanium content of the main types of soil in my country is generally high, but most of them exist in the soil in the form of water-insoluble oxides or silicates, and soluble titanium The average concentration is below 1ppm. Obviously, the content of soluble titanium in my country's soil is far from meet...
