1. The whitening agents prepared in examples 1-3 and comparative examples 1-4 were stirred uniformly and filtered for performance testing, wherein the drying time was tested by the surface dry method B, and the viscosity was tested by the viscosity testing method of GB/T9755-2014, and the results are shown in Table 1:
TABLE 1
2. The whitewash prepared in examples 1-3 and comparative examples 1-4 were stirred and filtered uniformly and then tested in the field.
(1) The experimental site: in a certain orchard in Guiyang City of Guizhou province, the experimental month is 10 months to 2 months in the next year. Selecting 70 walnut trees with the diameter at breast height of about 15cm, dividing the walnut trees into 7 groups, wherein each group comprises 10 walnut trees, and the coating height is 1 m; selecting 70 passion fruit trees with the diameter of about 2cm in total, dividing the passion fruit trees into 7 groups, wherein each group comprises 10 passion fruit trees, and the coating height is 80 cm;
(2) after brushing, observing whether the white coating has powder falling (whether the white coating has white powder when being touched by a hand after drying), cracking (the white coating cracks), blocky falling (the blocky falling size of the white coating is less than or equal to 2cm), large-piece falling (the blocky falling size of the white coating is more than 2cm) and falling (the area exposing the original tree color is more than or equal to 70%), simulating medium rain washing (3-4 mm of rainfall per hour) on the white coating after 5 days of experiment, continuously spraying for 7 days, washing for 3 hours every day, and after 7 days, managing and protecting with other fruit trees in the garden by the same method.

meanwhile, the passion fruit trees coated with the whitening agent are observed, and according to the embodiment or the comparative example with the walnut green seedcases, fewer ants are found on the passion fruit vines, and ants climb on the passion fruit vines of the comparative example 1 or other passion fruit trees which are not coated with the whitening agent.
Data analysis and conclusion:
1. the comparative example 1 is a conventional whitening agent, is coated on a trunk, has serious powder shedding, poor adhesion and long drying time, has the condition of large-scale shedding after being washed by water, completely shed in 30 th day, and cannot play the roles of resisting cold and freezing.
2. Compared with the fermentation liquor of the walnut green seedcase in the example 1, the fermentation liquor of the walnut green seedcase is directly adopted, compared with the fermentation liquor of the walnut green seedcase in the example 1, the cracking phenomenon appears in the 10 th day, the large-piece falling phenomenon appears in the 60 th day, the extraction liquor of the walnut green seedcase after secondary extraction with ethanol contains a large amount of naphthoquinones, polyphenols, terpenes and other compounds, the polyacrylamide gel can be obviously modified, and the adhesion and the cracking prevention capability of the whitening agent can be obviously improved after the polyacrylamide gel is mixed with calcium carbonate and the like.
3. In contrast, comparative example 3, which did not use polyacrylamide gel, showed earlier powder shedding, cracking, and the like, and failed to perform the same function as the whitening agent, similar to comparative example 1.
4. The walnut green husk juice directly adopted in the comparative example 4 cracks after being washed by water on day 5 and basically completely falls off on day 90, which shows that the walnut green husk can well cooperate with polyacrylamide gel after being fermented and extracted, and the cold-proof, freeze-proof and anti-falling purposes of the whitening agent are achieved.
5. The comparative example 5 directly adopts the calcium carbonate mixture and the polyacrylamide gel to prepare the whitening agent which has overlarge viscosity, although the whitening agent cracks after 90 days, the whitening agent does not fall off after 120 days, and the long-term adhesion of the whitening agent on the trunk can cause the reduction of the pesticide effect when the pesticide or the bactericide is sprayed in the later period, thereby being not beneficial to the planting benefit.
6. The drying time of the whitening agent of the examples 1-3 is shorter than that of the conventional whitening agent formula of the comparative example 1, the viscosity is higher, the whitening agent can be better attached to a trunk, and the whitening agent of the examples 1-3 can still keep no powder falling and no cracking after 7 days of rainwater simulated washing until a whitening layer falls off after 120 days, so that the effects of freezing prevention and cold resistance are achieved.
7. The artificial observation shows that the whitening agent added with the walnut green husk can prevent insect ants and pests from being abused and can reduce the artificial planting cost.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the spirit and scope of the invention as defined in the appended claims.
