Problems solved by technology

However, the natural environment is difficult to control artificially. For example, if there is no rain for a long time, the humidity will be low. In the case of rainy weather and long-term rainfall, the humidity will be high.
However, the cutting propagation of yew has relatively high requirements on light, temperature, and humidity, and the natural environment cannot meet its propagation requirements, requiring more manpower and material resources, and the survival rate is lower than that of seed propagation.

Abstract

The invention relates to a Taxus chinensis var.mairei seedling breeding method and belongs to the technical field of plant cultivation. The method comprises the following steps: collecting seeds, removing moisture after preparation, storing the seeds in a room, carrying out land preparation, applying a base fertilizer on the ground, sowing, shading, paying attention to watering and drainage, fertilizing and managing to obtain shoots, transplanting, digging a pit in the room, and carrying out piled storage. Stratification by digging the pit in the room is less influenced by external environment, and temperature, humidity and the like can be manually controlled. Thus, environmental conditions required by seed stratification are guaranteed, and seeds can be effectively prevented from being mildewed during the storage process.

Description

technical field [0001] The invention relates to a seedling breeding method of southern yew, belonging to the technical field of plant cultivation. Background technique [0002] Yew is an evergreen tree, the branchlets turn yellow-green or light reddish brown in autumn, the leaves are strip-shaped, dioecious, and the seeds are oblate. The seeds are used to extract oil and can also be used as medicine. It is a shallow-rooted plant with inconspicuous main roots and well-developed lateral roots. It is 30m high and 1m in dry diameter. The leaves are spiral and alternate, the base is twisted into two rows, the strip is slightly curved, 1-2.5cm long, 2-2.5mm wide, the leaf margin is slightly recurved, the leaf tip is acuminate, and there are 2 broad yellow-green or gray-green stripes on the back of the leaf Stomatal zone, with small bumps densely growing on the midrib, very narrow green band on leaf margin, dioecious, male cones solitary in leaf axils, ovules of female cones soli...
