Sunscreen cream for sunlight burns resistance of plants, its manufacturing method and its application

Abstract

The invention relates to a sunscreen cream for sunlight burns resistance of plants, its manufacturing method and its application, and is used for preventing and controlling sunlight burns of high temperature and strong sunlight in summer to crops, fruit trees, vegetables and flower seeding. The sunscreen cream comprises the following raw materials by weight: 1 part of refined kaolin; 0.3 to 2 parts of titanium dioxide; 0.05 to 0.3 parts of dispersing agent NNO; 0.08 to 0.15 parts of water-soluble chitosan; 0.2 to 0.5 parts of starch and 0.01 to 0.03 parts of betaine. The sunscreen cream provided in the invention has the advantages of no pollution, no harm, no residue, simple preparation and biological safety, and has good dispersibility and a certain viscosity in water. A white loose coating layer can be formed after the spayed plant surface is dried, and has a certain light reflection, light-profness and good permeability, so that the surface temperature of the plant organs as well as the transpiration rate can be reduced. The sunscreen cream provided in the invention is used for preventing and controlling sunlight burns of high temperature and strong sunlight to the plant organs, and is capable of raising survival rate of the transplanting nursery stock, raising crops output, fruit and vegetable product quality and the survival rate of transplanting seedings without affecting the air exchange of the plants.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation environment condition regulation, and is used for preventing and controlling the sunburn of crops, fruit trees, vegetables and flower seedlings caused by high temperature and strong light in summer, reducing the transpiration rate, improving crop yield, fruit and vegetable product quality and the survival rate of transplanted seedlings. In particular, it relates to a plant anti-sunburn sunscreen and its preparation method and application. Background technique [0002] From June to July in summer, some plants are vulnerable to strong light and high temperature, causing physiological diseases, which are called sunburn. In mild cases, it will cause poor plant growth, reduce yield and product quality, and in severe cases, it will cause plant death. For example, apples, pomegranates and other fruits are burned by the sun to form dark brown burn spots on the surface of the fruit, reducing thei...

Problems solved by technology

Bagging treatment is time-consuming and labor-intensive, and the cost is high; the cost of sunshade net treatment is higher, and it is only suitable for use in small areas such as greenhouses and gardens, and it is difficult to promote the use of plants in wild fields

Another way is to spray a certain concentration of lime milk, but the lime milk contains a certain amount of Ca(OH) 2 , has a certain degree of corrosiveness, and has poor air permeability, which is harmful to plants
