The invention discloses a method for detoxification and rapid propagation of the stem tip of lucky bamboo. The present invention specifically includes the following steps: (1) preparation of attenuated seedlings; (2) disinfection of materials; (3) dark treatment of materials; (4) induction of clustered buds; (5) detection of virus-free seedlings (Badnavirus); 6) Subculture proliferation of clustered buds; (7) Rooting culture; (8) Seedling hardening; (9) Material transplanting. The invention proposes a virus-free and rapid propagation technology for the stem tip of Lucky Bamboo, which has the advantages of simple operation and low cost, and can efficiently obtain a large number of high-quality virus-free seedlings in a short period of time, avoiding species degradation caused by asexual cutting propagation, and is large-scale industrialization Seedlings provide an effective way.

The invention discloses a method for promoting rapid growth of buds and roots of dracaena sanderiana. The method specifically comprises the following steps that S1, fresh dracaena sanderiana is selected, and the stem of the dracaena sanderiana is sheared off and inserted into culture solution with the PBU concentration being 2.0-10.0 mg / L or culture solution with the PBU concentration being 0.0-10.0 mg / L and the Sudaduo concentration being 1 mg / L; according to the inserting mode, the lower end of the stem of the dracaena sanderiana is firstly soaked in the culture solution for a period, then the upper end of the stem of the dracaena sanderiana is arranged in the culture solution for a period; S2, the stem, processed in the step S1, of the dracaena sanderiana is arranged in IAA rooting culture solution with the concentration being 0.05-10.00 mg / L, or IBA rooting culture solution with the concentration being 0.25-10.0 mg / L or NAA rooting culture solution with the concentration being 0.05-0.10 mg / L, so that the stem is cultured to promote growth of the root. The dracaena sanderiana processed through the growth method has the advantages of being high in sprouting speed, high in germination rate, multiple in bud number, low in flower withering rate and death rate and the like, and the method can be applied to cultivation of dracaena sanderiana in a large scale.

The invention provides a plant foliar bactericide with the antifreezing function, relating to the technical field of pesticides. The plant foliar bactericide is prepared from a bactericidal composition and an antifreezing composition in a ratio of 1:2, wherein the bactericidal composition comprises the following components in parts by weight: 5-15 parts of garlic powder, 10-30 parts of lime powder, 0.1-1 part of alkaloids from tea, 0.1-2 parts of capsaicin, 5-15 parts of calcium hypochlorite and 20-55 parts of hydrogen peroxide; the antifreezing composition comprises the following components in parts by weight: 5 parts of pine needles, 5 parts of dracaena sanderiana, 5 parts of cinnamomum camphora, 15 parts of chimonanthus praecox, 15 parts of holly, 1 part of wheat seedling, 3 parts of oxyspora paniculata, 0.05 part of antifreezing fluid for automobiles, 0.01 part of castor oil and 0.1 part of preservative. The plant foliar bactericide can be used for perennial plants in most parts of China, such as all the vegetables, fruit trees, flowers and plants and bonsai, can enhance the water retention and cold resistance of the plants, has relief and recovery effects on the plants suffering moderate and mild freezing injuries, adds chlorophyll, increases the yields and quality of crops and lengthens the green period.

The invention discloses a cosmetic additive with a whitening function as well as a preparation method and an application of the cosmetic additive. The cosmetic additive is prepared from raw materialsin parts by weight as follows: 8-13 parts of white truffle extract, 10-25 parts of folium eriobotryae extract, 12-28 parts of root of dracaena sanderiana, 6-18 parts of berchemia sinica and 70-128 parts of water, wherein the white truffle extract is extractive matter prepared from methanol extract of white truffle by dissolving with water and extraction with petroleum ether, cyclohexane, chloroform or benzene, and volume percentage concentration of methanol is 40%-48%; the folium eriobotryae extract is water extract, ethanol extract or water-ethanol mixture extract of folium eriobotryae. The cosmetic additive has higher tyrosinase activity inhibition ratio and better freckle removing effect; the raw material components are simple and safe and are beneficial for protecting body health of people; the preparation method is simple and easy to implement, conditions are mild, and industrial production is facilitated.
