Embodiment 1

[0043]The high-whiteness fiber composite membrane liquid for preventing and treating sunburn of fruits provided in this example is made of the following raw materials: 15 g of cellulose acetate, 15 g of polyvinyl alcohol, 2 g of sodium lauryl polyether carboxylate, and 45 g of nanometer calcium carbonate , kaolin 10g, acetic acid 3g, tetra-n-butyl titanate 2g, deionized water 100g.

[0044] The particle size of the nanometer calcium carbonate is 50nm.

[0045] The preparation method of the high-whiteness fiber composite film liquid for preventing and treating fruit sunburn comprises the following steps:

[0046] (1) According to the above dosage relationship, select cellulose acetate and polyvinyl alcohol and place them in deionized water, then heat up to 45°C, stir at a speed of 1000r / min for 20min, and mix well;

[0047] (2) Then add kaolin and drop tetra-n-butyl titanate, stir at 800r / min for 20 minutes at 25°C, then drop acetic acid, and stir for 20 minutes to obtain tita...

Embodiment 2

[0060] The high-whiteness fiber composite film liquid for preventing and treating fruit sunburn provided in this example is made of the following raw materials in proportion by mass: cellulose acetate 10, polyvinyl alcohol 20, sodium laureth carboxylate 1, nano Calcium carbonate 50, kaolin 9, acetic acid 3, tetra-n-butyl titanate 1, deionized water 120.

[0061] The preparation method refers to Example 1.

[0062] In this example, the obtained high-whiteness cellulose composite film liquid is diluted 8 times, and the whole citrus plant is sprayed with a conventional sprayer, and the anti-sunburn effect on 7 days, 14 days, 21 days, 28 days, and 35 days is 96.23% respectively. , 95.78%, 94.96%, 92.89%, 92.15%, the anti-sunburn effect is much higher than lime powder and no treatment.

Embodiment 3

[0064] The high-whiteness fiber composite membrane liquid for preventing and treating fruit sunburn provided in this example is made of the following raw materials in proportion by mass: cellulose acetate 20, polyvinyl alcohol 10, sodium laureth carboxylate 3, nano Calcium carbonate 40, kaolin 12, acetic acid 1, tetra-n-butyl titanate 3, deionized water 80.

[0065] The preparation method refers to Example 1.

[0066] In this example, the obtained high-whiteness cellulose composite membrane liquid was diluted 8 times, and the whole citrus plant was sprayed with a conventional sprayer, and the sunburn prevention effects were 95.82% in 7 days, 14 days, 21 days, 28 days, and 35 days. , 95.13%, 94.65%, 93.88%, 91.76%, anti-sunburn effect is much higher than lime powder and no treatment.

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...
