Non-test tube rapid propagation method of yew

Abstract

The invention discloses a taxus media non-test tube rapid propagation method which comprises the following steps of: (1) branch selection: selecting new branches growing on taxus X media in the same year and shearing to obtain two bundles of coarse and thin branches for standby; (2) seedbed substrate processing: deeply ploughing, unpacking, setting up a shed, disinfecting, sprinkling turfy soil and paving fine river sand; (3) rooting solution preparation: preparing amino acid, nitrogen, phosphorus, potassium, calcium, naphthylacetic acid, indole butyric acid, alcohol, white sugar and abt rooting agents; (4) branch soaking: soaking the fine branches obtained in the step (1) into rooting solution obtained in the step (3); (5) inserting; and (6) carrying out heat and moisture preservation on a seedbed. The taxus X media non-test tube rapid propagation method has the benefits that through carrying out technical innovation in aspects of branch selection, classification, seedbed substrate processing, rooting solution preparation and classified soaking, the purposes of high survival rate and high propagation speed are realized, the taxus X media can be quickly inserted and propagated on a large scale, and the mass propagation and the anticancer application of the taxus X media are facilitated.

Description

technical field [0001] The invention relates to a yew cutting propagation method, in particular to a non-test tube rapid propagation method of the yew with high survival rate and fast propagation speed. Background technique [0002] Yew is a shallow-rooted plant with inconspicuous main roots and well-developed lateral roots. It is recognized as a rare natural anti-cancer plant on the verge of extinction in the world. "And "money tree", "paclitaxel" extracted from Taxus mandia as the main raw material is a broad-spectrum anti-cancer natural plant product with unique structure, safe performance and effective killing of cancer cells. cancer effect. [0003] Because the propagation of seedlings with yew seeds has the disadvantages of slow germination (two years), long period of germination, low seed germination rate, and slow growth of seedlings, it is an ideal choice to propagate yew by cuttings. Using cutting technology to quickly cultivate yew seedlings has the characterist...

Problems solved by technology

[0007] 3. The rooting agent is relatively simple. Soak it with ordinary rooting agent and insert it. Some soaking time is too long. Ordinary rooting agent does not add amino acids and other trace elements, so the survival rate of cuttings is relatively dependent, and the emergence and transplanting are slow. Generally, one ton 80,000 to 100,000 branches survive, and it takes 18 to 20 months to transplant

[0008] Due to the above-mentioned defects, the traditional yew cutting propagation method is difficult to achieve the effect of fast and large-scale cutting propagation of yew, which restricts the mass propagation and anti-cancer application of yew
