Cold-resistant cypress breeding method

Abstract

The invention relates to a method for breeding cold resistant draping thread cedar, which can meet demand of sight plant in cold area of minus 18 Deg. C, comprising following steps: immersing seed which stored at temperature under 0 Deg. C for at least 10 months, then sowing, covering with film, spraying mono-basic potassium phosphate mixture when autumn tip is over 10 cm after seedling growing out to promote branch mature, then cutting, treating seed bed firstly, cutting draping thread cedar branch secondly, immersing in mixture of root-growth and sterilizing, furrow cutting or ridge cutting, covering with film and shading to maintain proper soil humidity and air humidity until seedling grows out, then replanting for growth. The invention is characterized by simple method, good breeding effect and high breeding rate, which solves problem of asexual propagation for draping thread cedar and develops a bright future for sight-seeing plant application.

Description

1. Technical field [0001] The invention relates to a breeding method of cold-resistant cypress. 2. Background technology [0002] Cedar cypress is an evergreen tree belonging to the family Cupressaceae. It is a cold-resistant variety of cypress. Because its branches and leaves are soft and naturally drooping, it is called Cedar cypress. It is a rare landscape tree species. [0003] With the development of the garden industry, people pay more and more attention to the beautification of the environment. At present, most of the beautification plants in the north are deciduous plants, and there are few evergreen plants in all seasons. As a landscape plant for greening the environment, there is a kind of cypress in the northern mountainous area, but because of its weak reproductive ability and no seed cultivation, it cannot be used in urban and rural garden landscapes, and the southern cypress cannot grow normally in the north due to poor cold resistance. And planting, which doe...
