Embodiment Construction

[0031] A method for growing seedlings by cuttings of yew, comprising the following steps:

[0032] (1) Selection of spikes

[0033] Cut the semi-lignified branches of the middle and lower part of the canopy of the 4-8-year-old mother tree or the branches that germinate from the roots as spikes;

[0034] (2) Treatment of spikes

[0035] The cut fringes are washed with clean water and put into carbendazim solution for sterilization and disinfection. The disinfection time is 5 minutes, and then the fringes are cut. For all branches and leaves, keep 3 to 5 axillary buds or side terminal buds. The incision is smooth, not broken, not split, and the lower end is cut into a horse-ear shape. 4.8-5.2cm;

[0036] (3) Cuttings of spikes

[0037] Cuttings are carried out in early and mid-October. The seedbed width is 1.25m, the bed height is 40cm, the cutting depth is 5-8cm, and the distance between rows and plants is 4cm×5cm.

[0038] (4) Management after insertion

[0039] Spray wa...

Abstract

The invention relates to a cutting and breeding method for taxus chinensis, and belongs to the technical field of plant breeding. The cutting and breeding method comprises the following steps: scion wood selection, scion wood treatment, scion wood cutting, management after cutting, seedling transplantation, and management after transplantation. The adopted cutting and breeding method has the advantages that the cutting and breeding method with high survival rate is provided for taxus chinensis breeding in the south, the planting range of taxus chinensis is enlarged, and the difficult problem of taxus chinensis resource shortage can be favorably solved.

Description

technical field [0001] The invention relates to a method for growing seedlings of yew by cuttings, belonging to the technical field of plant cultivation. Background technique [0002] Yew is a shallow-rooted plant with inconspicuous main roots and well-developed lateral roots. It is a shade-tolerant tree species that likes warm and humid climates. It usually grows in relatively humid places in the hinterland at the foot of mountains. It naturally grows in acidic soil rich in humus in valleys, streams, and gentle slopes at an altitude of 1,000 meters or below 1,500 meters. It requires higher fertility yellow soil, yellow brown soil, neutral soil, and calcareous soil. It is resistant to drought and barren, and it is not tolerant to low-lying water. It has strong adaptability to climate, with an average annual temperature of 11-16°C, and the lowest extreme value can reach -11°C. It has strong germination ability, and there are many sprouting twigs on the trunk. Due to the slo...
