High-whiteness fiber composite membrane liquid for preventing and treating fruit sunscald and preparation method and application thereof

Abstract

The invention discloses a high-whiteness fiber composite membrane liquid for preventing and treating fruit sunscald. The high-whiteness fiber composite membrane liquid is prepared from the following raw materials in parts by mass: 10-20 parts of cellulose acetate, 10-20 parts of polyvinyl alcohol, 1-3 parts of sodium laureth carboxylate, 40-50 parts of nano calcium carbonate, 9-12 parts of kaolin, 1-3 parts of acetic acid, 1-3 parts of tetra-n-butyl titanate and 80-120 parts of deionized water. The high-whiteness fiber composite film liquid can be directly sprayed on the surfaces of fruits, the labor cost is low, the risk that the fruits are burnt by high-intensity sunlight can be remarkably avoided, and the occurrence probability of sunburn spots and sun fruits is reduced. The invention further discloses a preparation method of the high-whiteness fiber composite membrane liquid and application of the high-whiteness fiber composite membrane liquid to prevention and treatment of fruit sunscald.

Description

technical field

[0001] The invention belongs to the technical field of fruit films, and in particular relates to a high-whiteness fiber composite film liquid for preventing and treating fruit sunburn, a preparation method and application thereof. Background technique

[0002] Sunburn is a common physiological disease in the planting stage. It is not contagious and can occur in both northern and southern fruit trees. The general occurrence time is from June to September when the sun is exposed to high temperature, and the fruits in the expansion stage are more likely to suffer from sunburn, and become commonly known as "sun fruit". If pesticides are sprayed at this time, it will aggravate the condition of sunburn. According to statistics, the loss of the majority of fruit farmers nationwide due to sunburn accounts for 3-5% every year, the loss of general fields accounts for 7-8%, and the loss of high-yield and serious fields accounts for 15-30%. The traditional control metho...
