Preparation method for tree trunk whitening agent

Abstract

The invention discloses a preparation method for a tree trunk whitening agent, and belongs to the technical field of agricultural material preparation. The preparation method for the tree trunk whitening agent comprises the following steps: first, sealing and fermenting bean curd, chilli powder, nutmeg powder and the like, filtering, collecting fermentation liquor, and mixing the fermentation liquor and sterile water, saccharose, citric acid and the like; then, performing constant temperature culture on a mixture, and mixing and fermenting with the plants, such as herba portulacae and chrysanthemum; sterilizing by utilizing ultraviolet light; collecting a fermented mixture, pulping, and performing centrifugal treatment with activated carbon; concentrating the obtained supernatant, and stirring uniformly with the supernatant, quick lime, hydroxymethyl cellulose and the like; finally, collecting the mixture, and performing sterilizing and disinfecting to obtain the tree trunk whitening agent. The tree trunk whitening agent prepared with the preparation method is purely white in colour and high in covering property; by adding the substances with high adhesive force and good film forming property, all of the adhesive property, the film forming property and the rainwater erosion resistance of the whitening agent can achieve a lasting effect; meanwhile, the whitening agent does not peel off easily after being used, has a relatively good heat preserving effect and a pest and disease damage preventing effect, is required to be applied only once, and has an excellent application prospect.

Description

technical field [0001] The invention discloses a preparation method of a tree trunk whitening agent, which belongs to the technical field of agricultural material preparation. Background technique [0002] In winter, many trees need to be whitewashed, that is, at a certain height of the trunk and main branches, a layer of whitening agent is applied to prevent insect damage, sunburn and freezing damage. White coating has the following advantages: (1) White coating of trees can effectively prevent freezing damage to garden trees in winter. Because white has a reflective effect and absorbs less heat, trees will not be significantly affected by drastic changes in day and night temperatures, which can prevent and reduce sunburn, Freeze injury; (2) trees can also be prevented from invading after being painted white, because lime has certain bactericidal and insecticidal effects, which can kill some overwintering fungi, bacteria and pests parasitic on the trunk; (3) trees can be wh...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: aiming at the disadvantages of the traditional tree trunk whitening agent, such as poor viscosity and film-forming property, prone to cracking and peeling off, short protection time, poor insect-proof and anti-bacteria effect, and inability to add pesticide ingredients during application, it provides a The target mixed strains are obtained by fermenting tofu, and the mixed strains are cultivated. Glutamic acid is used as an attractant nutrient and manganese sulfate is used as an inducer to screen and cultivate the mixed strains to obtain the target strains, and then combine them with natural The plants are fermented to obtain insecticidal and beneficial substances in the plants, and finally mixed with quicklime, etc., the viscosity is increased through hydroxymethyl cellulose, the bonding force with the trunk is increased by adding silicone oil, and the trunk is protected by whitening agent to obtain the trunk The method of whitening agent, the present invention first seals and ferments tofu, chili powder, cardamom powder, etc., filters and collects the fermented liquid and mixes with sterile water, sucrose, citric acid, etc., and then mixes the mixture with purslane and chrysanthemum after constant temperature cultivation Wait for plants to mix and ferment and use ultraviolet light to sterilize, collect the fermented mixture and refine it, and then centrifuge it with activated carbon, then concentrate the obtained supernatant and mix it with quicklime, hydroxymethyl cellulose, etc., and finally collect the mixture for sterilization to obtain Trunk whitening agent, the trunk whitening agent prepared by the present invention has good covering property, and by adding substances with strong adhesion and good film-forming property, the adhesiveness, film-forming property and rainwater erosion resistance of the whitening agent can all reach lasting At the same time, the whitening agent is not easy to peel off after use, and has good heat preservation, water retention and pest prevention effects. It can last for 14 to 18 months with only one brushing, and has an excellent application prospect.
