Embodiment 1

[0022] 1) Take 1-year-old tree crown middle and upper thick branches or sprouting strips of cutting piles, the length is 10cm, leave a top tip for each, cut off the remaining side branches and leaves, and use a knife to cut into horseshoe oblique openings at the branches as the lower opening of the cutting branches ;

[0023] 2) Put the lower mouth of cuttings into 50mg / L ABT1 rooting powder solution for quick dipping treatment for 5s;

[0024] 3) Select sawdust and river sand with a mass-to-number ratio of 3:2 as the seedbed substrate, and the thickness of the seedbed substrate is 20cm;

[0025] 4) Apply 40% formalin on the seedbed substrate to disinfect the seedbed substrate;

[0026] 5) Water the seedbed once and cover it with plastic film;

[0027] 6) Insert the cuttings from step 1) into the seedbed substrate at a depth of 3cm, and control the temperature of the seedbed at around 25°C to avoid direct sunlight;

[0028] 7) Water once a day, and spray 700 times carbendaz...

Embodiment 2

[0032] 1) Take the middle and upper part of the 2-year-old tree crown, the thick branches or the sprouting strips of the cutting pile, the length is 15cm, leave a top tip for each branch, cut off the remaining side branches and leaves, and use a knife to cut into a horseshoe slant at the branch as the lower opening of the cutting branch ;

[0033] 2) Soak the lower mouth of cuttings in 500 mg / L indole butyric acid solution for 1 hour;

[0034] 3) Select river sand, sawdust, and eroded soil with a mass-to-number ratio of 3:2:1 as the seedbed substrate, and the thickness of the seedbed substrate is 25cm;

[0035] 4) Apply quicklime on the seedbed matrix to disinfect the seedbed matrix;

Abstract

The invention discloses a taxus chinensis cuttage cultivation method. The taxus chinensis cuttage cultivation method comprises the steps as follows: inserting insertion branches treated with plant hormones onto a prepared seedbed substrate in sequence, controlling the cuttage depth to be 3-6 cm, watering each day, spraying a 700-time carbendazol solution once each week, after half a month, reducing the watering frequency, averagely watering once every 3 days, spraying the 700-time carbendazol solution once every two weeks, and transplanting for cultivating after the insertion branches take roots. The method has the advantages that firstly, as the seedbed substrate adopted in the method is better in physical permeability, formation, rooting and after-rooting growth of callus tissues are facilitated; secondly, saw powder is good in heat retaining property and the temperature difference between day and night for the substrate is slightly changed, so that rooting is facilitated; and thirdly, a small amount of humus soil is strong in water and fertility retaining capability, so that growth of root systems and new branches of nursery stocks is facilitated; the seedbed substrate is disinfected at the same time, so that the insertion branches are effectively prevented being infected with pathogenic bacteria; and the insertion branches are sprayed with the carbendazol solution after cuttage, so that the cuttage rooting is facilitated, the survival rate is increased, and the seedling growth time is shortened.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a cutting cultivation method of yew. Background technique [0002] Yew, also known as yew, is a precious tree species protected at the national level, and the natural forest resources have been exhausted. Yew is an evergreen tree with a straight trunk and a beautiful tree. When the seeds are ripe, it turns red and the fake skin is bright and eye-catching. It is an excellent bonsai and greening tree species. Yew wood is strong and durable, with beautiful texture. The roots and stems are high-grade carving materials, which are special forest materials. Menstruation, diuresis, blood pressure lowering, have obvious effect on preventing and treating diabetes and cardiovascular disease, it is a valuable medicinal forest. Many countries list it as a "national treasure". [0003] At present, the cultivation of yew mostly adopts the method of cutting cultivation, but the exis...
