Abstract

The present invention relates to a high-effective water soluble rooting powder for Mandiya taxus, belonging to a fast propagation technique for forest tree seed seedling. It uses alpha-naphthylacetic acid and sodium salt or potassium salt powder of indolylbuteric acid as main component, mixes them according to the ratio of 1:0.6-1.5 to obtain the invented rooting powder. In said powder material a proper quantity of rare earth microfertilizer also can be added. Besides, said invention also provides the application method and concrete steps of said rooting powder.

Description

technical field [0001] The invention belongs to the rapid propagation technology of forest tree seedlings, in particular to a high-efficiency water-soluble rooting powder used for the cutting propagation of Taxus mandya. Background technique [0002] Since wani et al. extracted and isolated paclitaxel from the bark of Taxus brevifolia Nutt. and found that it has anti-cancer effects, researchers have successively discovered its unique anti-cancer mechanism and can treat a variety of cancer. [0003] Taxol is a diterpenoid isolated from the bark of Taxus brevifolia in 1971. It is a natural product with a unique anti-cancer mechanism, which can induce and promote the binding of tubulin, thereby preventing cancer. The proliferation of cells has cytotoxic effects on human ovarian cancer, breast cancer, cervical cancer, lung cancer, CNS cancer, melanoma, liver cancer and leukemia cell lines. It is the hottest anticancer drug after doxorubicin and cis...
