Fruit tree sunscreen cream and preparation method thereof

Abstract

The invention discloses sunscreen cream for fruit trees. The cream comprises the following components in parts by weight: 1-2 parts of lime powder; 1-2 parts of talcum powder, 0.8 to 1.5 parts of water soluble chitosan; 0.01 to 0.03 part of glycine betaine, 0.06 to 0.2 part of a humectant, 0.05 to 0.3 part of a dispersing agent, 0.2 to 0.5 part of a water-phase emulsifier, 0.2 to 0.5 part of starch, 0.8 to 1.5 parts of a seaweed extracting solution, 0.3 to 0.7 part of titanium dioxide, 0.2 to 0.6 part of a chelating agent and 3 to 4 parts of water. The prepared fruit tree sunscreen cream can prevent and control sunscald, promote fruit growth, improve the yield and quality of fruits, and achieve the integration of plant disease prevention and control and growth promotion.

Description

technical field [0001] The invention relates to the technical field of daily chemicals, in particular to a sunscreen for fruit trees and a preparation method thereof. Background technique [0002] From June to September, high temperature and drought, citrus fruits and leaves are continuously exposed to the hot sun and strong light, causing physiological lesions that hinder the growth of the peel and mesophyll, which is called sunburn in production; in the early stage of burn, oil will appear on the surface of the fruit When the cells rupture, the pericarp near it will lose its color and form light yellow spots, which will continue to spread into sheets. If the degree of sunburn is severe, the necrotic oil cells will turn black, and a sunken dry scar will appear in the center; but at this time due to The damage has not penetrated into the sponge layer, so the inner pulp is intact and the quality is not affected, but the lesions on the surface of the fruit become dark and acco...

Problems solved by technology

[0002] From June to September, high temperature and drought, citrus fruits and leaves are continuously exposed to the hot sun and strong light, causing physiological lesions that hinder the growth of the peel and mesophyll, which is called sunburn in production; in the early stage of burn, oil will appear on the surface of the fruit When the oil cells rupture, the pericarp near it will lose its color and form light yellow spots, which will continue to spread into sheets. If the degree of sunburn is severe, the necrotic oil cells will turn black, and a sunken dry scar will appear in the center; but at this time due to The damage has not penetrated into the sponge layer, so the inner pulp is intact and the quality is not affected, but the lesions on the surface of the fruit become dark and accompanied by sinking and cracking, and the juice cells are also granulated and lack water. At this time, the fruit is no longer edible Therefore, it is very important for the sun protection of fruit trees and the prevention and treatment of sunburn

[0003] At present, most of the sun protection technologies for citrus fruit trees are based on the traditional methods of the growers based on years of continuous experience and personal self-creation, such as lime powder spraying, water spraying, and bagging, among which lime powder spraying This method reduces the photosynthesis of plants and affects the tree vigor. The lime is easy to fall off after spraying, so it needs to be continued without spraying. At the same time, the lime remains on the peel and affects sales. Spraying water improves the humidity of the space and the microclimate of the orchard, bagging, work The amount is large, and it will affect the growth of the fruit at the same time, and the effect of sunscreen method is average
