Method of growing seedlings of taxus mairei

Abstract

The invention belongs to the technical field of cultivation of taxus mairei, and in particular relates to a method of growing seedlings of taxus mairei. The method comprises the steps of: harvesting and storing seeds, selecting and treating a garden, sowing, exposing grass and shading, managing seedling, carrying out pest control, outplanting and grading nursery stock. According to the method of growing seedlings of taxus mairei provided by the invention, by adopting seeds subjected to sand storage, humidification and natural temperature stratification, the integrated germination rate is more than 95%. Through reasonably designing a process for exposing grass and shading, managing seedling, and carrying out pest control, the cost for growing the seedlings of the taxus mairei is reduced, and the integrated survival rate is increased.

Description

technical field [0001] The invention belongs to the technical field of southern yew cultivation, and in particular relates to a method for cultivating southern yew seedlings. Background technique [0002] At present, about the cultivation of the southern yew, there are mainly the following defects: [0003] 1. The seeds of Taxus chinensis are typical morphology-physiological dormant seeds. For mature seeds without special treatment, they need to be treated for more than one year (two winters and one summer) to relieve dormancy. The overall germination rate Generally low (about 50-60%). [0004] 2. Southern yew seedlings are very susceptible to diseases. If the shade shed is set up too late, the rhizomes will turn yellow and brown due to sunburn and suffer from damping-off disease. Too much rain and poor drainage will easily cause root rot. [0005] 3. Southern yew seedlings grow slowly and have weak resistance. Therefore, under the premise of setting up shade sheds in time...
