Rapid Cuttage Propagation of Taxus chinensis

Taxus is a national first-class protected plant, which is an evergreen tree, mostly distributed in the Northern Hemisphere. Its bark, stem, leaf and root can extract paclitaxel, which has a special effect on the treatment of cancer. We successfully introduced Taxus in the spring of 1996. The techniques of cutting propagation are briefly introduced as follows:

1. During the cutting period, Taxus can be propagated three times a year in March, July and November, respectively.

Second, to build a cutting bed, if you want to cut a small amount of yew, you can use pot cuttings, and if you have a large amount, you should build a cutting bed. The cutting bed is generally 2.5 meters wide, leaving a walkway 30 centimeters wide in the middle, about 20 centimeters wide with bricks around, 10 centimeters on each edge, putting a layer of coarse sand about 20 centimeters thick, and adding a small amount of sterilized nutrient soil. The cutting bed supports the arch frame, which is covered with plastic film for heat preservation and moisturizing.

Third, cuttings are generally prepared to use yew branches about 10 centimeters long as cuttings. Remove the leaves at the bottom of the cuttings with a shears or a sharp knife, bind them into a handful of 100 cuttings every 50 murals, soak them in ABT rooting powder with l00xl0-6 concentration for about 6 hours, remove and wash the cuttings with clean water.

Fourth, the row spacing of cuttings and transplanting cuttings is 5cm, and the plant spacing is 1cm. The seedlings raised by cutting in March should be sprayed with water once after cutting, covered with plastic film for heat preservation and moisturization, and covered with sunshade net to cool down. When the cutting bed temperature exceeds 25 ℃, it should be ventilated and cooled in time. Spray water on the cutting bed at noon on a sunny day. Cutting seedlings in July, spray once after cutting permeable, can not be covered with plastic film, directly covered with sunshade net. Spray water several times a day on sunny days, and spray water once at noon on sunny days after cutting for half a month. Generally check the rooting of cuttings before and after October 1, if the cuttings have taken root, you can transfer seedlings, spray water once after moving seedlings, and cover the sunshade net. It can survive the winter safely in the open field after 1 month. If the seedlings are raised by cutting in November, they shall be sprayed with water once after cutting, covered with plastic film for heat preservation, and covered with sunshade net in March of the following year. Generally, cuttings begin to take root in May, and transplantable seedlings are planted in July.
