A cultivation method for high-quality seedlings of taxus cuspidate

Abstract

The invention provides a cultivation method for high-quality seedlings of taxus cuspidate and relates to the field of seedling planting. The method comprises the steps of: oil preparation and bedding: deeply ploughing and fully cultivating planting land, performing ditching and bedding and then performing fertilizing, tilling and watering; seed selection and processing: collecting seeds of taxus cuspidate, drying the seeds, controlling the water content of the seeds of taxus cuspidate, and storing the seeds for seeding; seeding management: performing tilling once before seeding, performing deep tilling and shallow seeding, mulching the seeds after sowing, and taking off the plastic film after sprouts emerge from soil; seedling culture management: applying an insecticide and fertilizer once every month, trimming branches when seedlings grow to 15cm, performing grafting according to a square budding method, removing peripheral weeds and performing thinning; branch clipping: cutting excessively-growing branches and overcrowded branches to maintain a proper density of tree forms. The method is low in planting cost and can increase the sprouting rate and survival rate of seeds and shorten the outplanting period of finished-product taxus cuspidate; cultured plants are good in growth vigor, high in quality and good and beautiful in shape and are neat and robust.

Description

technical field [0001] The invention relates to the field of planting seedlings, in particular to a method for cultivating high-quality seedlings of dwarf yew. Background technique [0002] Dwarf yew is a variety with high ornamental value bred from Northeast yew. Hemispherical dense vertical shrubs, short tree shape, beautiful tree posture, evergreen all year round; leaves grow in a spiral shape, in two irregular rows, obliquely spread at an angle of about 45° with the branchlets, strip-shaped, narrow base, short stalk, The apex is convex, the top is green and shiny, and there are two gray-green stomatal lines below. This tree species has strong shade tolerance, shallow roots, well-developed lateral roots, and slow growth; the aril is bright red and extremely bright. The flowering period is from May to June, and the seeds mature from September to October. It is very cold-resistant, and has strong resistance to shade, pruning, and fear of waterlogging; it likes to grow in...

AI Technical Summary

Problems solved by technology

[0004] High-quality seedlings are a necessary condition for the dignified and graceful formation of dwarf yew. The reasonable and scientific management of dwarf yew seedlings in the early stage affects the survival rate and appearance quality of the finished dwarf yew. However, the related conditions and factors are nothing more than soil , water, fertilizer, seedling management, etc., but the existing dwarf yew cultivation methods lead to low branching rate of seedlings, and the seedlings with weak growth potential are in a shaded state for a long time, causing a large number of seedlings to weaken, and the proportion of single-stem seedlings is high. The qualified rate of seedlings is low, the nursery period is long, and technical problems such as partial crown lodging, disordered crown shape, irregular forest appearance, and obvious differences in tree structure differentiation commonly occur in the young forest stage after afforestation.
