Description

Orange sun-proof and sun-proof material

Technical Field

The invention relates to the technical field of chemical products, in particular to a sun-proof and sun-proof material for oranges.

Background

The types of oranges are more, and due to the fact that the oil cells of peels of some varieties are thick and the peels of some varieties are thin, when the high temperature reaches over 38 ℃ in summer, ultraviolet UVA-UVB can damage the oil cells, so that the peels of the oranges are necrotic, and the commodity rate and the fruit price are reduced. In order to prevent the damage of the sun to the citrus, the sun-proof material is generally coated outside the peel to reduce the ultraviolet radiation, thereby protecting the fruit.

At present, most of the existing sun-proof products in the market are mixed by heavy calcium carbonate and glue and then coated on the surface of the peel, the calcium carbonate is white powder and can be attached to the surface of the peel through the glue to reflect light, but the glue belongs to an organic compound and contains a large amount of volatile organic compounds, and the organic compounds harmful to human bodies and the environment are released after being coated, so that the sun-proof products are in a way of being away from green products. If the glue quality is poor, calcium carbonate is difficult to attach to the surface of the peel; the glue is too strong in viscosity, and the fruits are difficult to clean and fade in the later period when harvested, so that the commodity value of the fruits is reduced, and the labor cost for cleaning during selling is increased. Meanwhile, the glue is attached to the surface of the pericarp and partial leaf surfaces to influence the photosynthesis of crops, so that the sugar content of fruits is reduced, the coloring uniformity is insufficient, and the tree body can gradually degenerate due to the failure of good photosynthesis, thereby reducing the life cycle of fruit trees. Accordingly, there is a need for improvements in the prior art that overcome the deficiencies of the prior art.

Disclosure of Invention

The invention aims to provide a citrus sun-proof and sun-proof material, which adopts light calcium carbonate as a main raw material, and has the advantages of citrus sun-proof and sun-proof functions, convenience in use, safety, environmental friendliness, cost saving and the like.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a sun-proof and sun-proof citrus material comprises the following components in percentage by mass: 85-86% of light calcium carbonate powder, 8-9% of SPF50 ultraviolet blocking agent, 3-4% of surfactant, 1-2% of paraffin oil and 0.5-0.8% of stabilizer.

According to the scheme, the orange sun-proof and sun-proof material comprises the following components in percentage by mass: 85.8 percent of light calcium carbonate powder, 8.6 percent of SPF50 ultraviolet blocking agent, 3.4 percent of surfactant, 1.6 percent of paraffin oil and 0.6 percent of stabilizer.

According to the scheme, the mass content of calcium carbonate in the light calcium carbonate powder is 49%.

The light calcium carbonate is used as a carrier part of a product, is superior to heavy calcium carbonate in absorption and utilization of the process, has better powder mesh number, can cover a wider coverage area of citrus oil cells, has more excellent adhesiveness, and can isolate and reflect certain ultraviolet rays through white color on the surface; the SPF50 ultraviolet blocking agent has high-efficiency ultraviolet blocking capability, and the blocking rate is as high as 99%; the surfactant is used for completely fusing calcium ions with the barrier agent; the paraffin oil does not participate in any reaction and is only used for surface attachment to resist the effect of rain wash, and the stabilizer enables the components to be stored stably. All the raw materials belong to safe, green and environment-friendly materials, and the sun-screening function can be maintained for a long time.

The invention has the beneficial effects that:

1) the product can selectively block UVA-UVB harmful light, effectively control sunburn damage caused by high temperature and ultraviolet rays, play a role in preventing sunburn and sunburn, and ensure normal illumination of fruits, uniform coloring and more excellent sugar content;

2) when the product is used, the photosynthesis of crops is not influenced when the sun-proof effect of the citrus is achieved, the crops naturally receive light, and the crops grow robustly;

3) the product is environment-friendly and pollution-free, has no added compound, has long sun-proof and sunburn-proof effects, is safe and environment-friendly, is convenient to use, and can meet the European Union export requirement;

4) after the product is used, the white calcium powder gradually falls off after being washed by rainwater, no residue is left on the surfaces of fruits in the harvest period, manual fruit washing during fruit receiving and retail is omitted, labor cost is saved, and commodity value of citrus is improved.

Detailed Description

The technical solution of the present invention will be described with reference to the following examples.

Example 1:

the invention provides a sun-proof and sun-proof citrus material, which comprises the following components in percentage by mass: 85.8 percent of 49 percent of light calcium carbonate powder, 8.6 percent of SPF50 ultraviolet blocking agent, 3.4 percent of surfactant, 1.6 percent of paraffin oil and 0.6 percent of stabilizer.

Example 2:

the invention provides a sun-proof and sun-proof citrus material, which comprises the following components in percentage by mass: 85 percent of 49 percent of light calcium carbonate powder, 9 percent of SPF50 ultraviolet blocking agent, 4 percent of surfactant, 1.5 percent of paraffin oil and 0.5 percent of stabilizer.

Example 3:

the invention provides a sun-proof and sun-proof citrus material, which comprises the following components in percentage by mass: 86 percent of light calcium carbonate powder with the content of 49 percent, 8 percent of SPF50 ultraviolet blocker, 3.2 percent of surfactant, 2 percent of paraffin oil and 0.8 percent of stabilizer.

Example 4:

Selecting a citrus orchard with the least resistance to sunshine, randomly selecting different provinces, selecting 8 experimental control areas in total, wherein each experimental area is 1 mu, and the planting density of citrus trees is 50-80 plants/mu, singly using the product of the invention to carry out whole-tree spraying, and using similar products and blanks to carry out result comparison, and the results are shown in table 1.

The application method comprises the following steps: 6-8 months: the whole tree is sprayed by adopting the mass ratio of the product to water of 1:80 and the mass ratio of the paraffin oil to water of 1:500, and the important point is that the fruit surface is more uniform; 8-10 months: the mass ratio of the product to water is 1:80, and the mass ratio of paraffin oil to water is 1:500, so that the whole tree is sprayed, the more uniform fruit surface is required, and the better the whiteness of the fruit surface is kept.

Note that: the use is avoided under the condition of raining or more serious dew, and the use is not recommended under the condition of raining within 6 hours; if the rain is continuously rainy and the rain is more and seriously washed, the best sun-proof effect can be achieved only by additional spraying; the product of the invention needs to be used independently.
