Embodiment 1

[0023] A protective agent for alleviating sunburn of fruits, comprising 6.8% titanium dioxide, 70% talc, 20% kaolinite, 3% gum arabic and 0.2% mannan by mass percentage.

[0024] The preparation technology of above-mentioned protective agent comprises the steps:

[0025] (1) Titanium dioxide, talc and kaolinite are pulverized by a Raymond mill to a fineness of 2000 mesh; gum arabic and mannan are pulverized by a jet mill to a fineness of 250 mesh to obtain pretreated raw materials.

[0026] (2) The above-mentioned pretreatment raw materials are weighed into the mixer according to the mass percentage as claimed in claim 1, and mixed by the mixer to obtain the protective agent.

[0027] Protective effect test: The protective liquid was prepared with a mass ratio of protective agent and water of 1:50, and the citrus fruit surface was sprayed 3 times with an interval of 20 days between each time.

Embodiment 2

[0029] A protective agent for alleviating sunburn of fruits, comprising 8% titanium dioxide, 62% talc, 25% kaolinite, 4.5% gum arabic, and 0.5% mannan by mass percentage.

[0030] The preparation technology of above-mentioned protective agent comprises the steps:

[0031] (1) Titanium dioxide, talc and kaolinite are pulverized by a Raymond mill to a fineness of 1000 mesh; gum arabic and mannan are pulverized by a jet mill to a fineness of 200 mesh to obtain pretreated raw materials.

[0032] (2) The above-mentioned pretreatment raw materials are weighed into the mixer according to the mass percentage as claimed in claim 1, and mixed by the mixer to obtain the protective agent.

[0033] Protective effect test: Protective agent and water were prepared with a mass ratio of 1:30 to prepare a protective liquid, and sprayed on the mango fruit surface twice with an interval of 15 days between each time.

Embodiment 3

[0035] A protective agent for alleviating sunburn of fruits, comprising 5% titanium dioxide, 65% talc, 26% kaolinite, 3.3% gum arabic, and 0.7% mannan by mass percentage.

[0036] The preparation technology of above-mentioned protective agent comprises the steps:

[0037] (1) Titanium dioxide, talc and kaolinite are pulverized by a Raymond mill to a fineness of 1500 mesh; gum arabic and mannan are pulverized by a jet mill to a fineness of 220 mesh to obtain pretreated raw materials.

[0038] (2) The above-mentioned pretreatment raw materials are weighed into the mixer according to the mass percentage as claimed in claim 1, and mixed by the mixer to obtain the protective agent.

[0039] Protective effect test: Protective agent and water were prepared at a mass ratio of 1:45 to prepare a protective solution, which was sprayed on the walnut fruit surface twice with an interval of 18 days.

Abstract

The invention relates to a protective agent for reducing fruit sunburn, which belongs to the technical field of plant protection, and is characterized by comprising the following components in percentage by mass: 5-10% of titanium dioxide, 50-70% of talc, 20-30% of kaolinite, 3-10% of Arabic gum and 0.2-1% of mannan. The preparation process comprises the following steps: crushing the raw materials, and mixing in percentage by mass; the protective agent is applied to fruit surfaces of citrus, mango, apple and walnut trees, the temperature of the fruit surfaces can be reduced by 3-10 DEG C, thesunburn fruit rate is reduced by 50% or above, meanwhile, all components of the protective agent are environmentally friendly, harmless to the fruit trees and free of pollution to the ecological environment.

Description

technical field [0001] The invention belongs to the technical field of plant protection, relates to a protective agent, in particular to a protective agent for reducing sunburn of fruits. Background technique [0002] In the hot and dry season, direct sunlight on the bare fruit tree branches and fruits can cause the surface temperature to reach above 40°C, which will burn the plants, especially causing serious losses to the high-quality production of fruit trees. In the early stage, the affected part of the fruit tree (the sunny side) partially turns white, and then light brown or black spots appear. Later, the lesion expands, and then dries up or even cracks, and even loses its edible value. In order to prevent sunburn, fruit bagging and white spraying are generally adopted. Measures such as irrigation and moisture conservation in the orchard can also be used to increase leaf volume and water supply, and Bordeaux mixture or lime water can also be sprayed on the fruit surfac...
