Problems solved by technology

Cotinus zixia has a high ornamental value, and its excellent characters can only be maintained through vegetative propagation, but at present, through grafting, cuttings and other vegetative propagation methods, its survival rate is very low

Embodiment 1

[0037] Embodiment 1, Zixia cotinus cotinus asexual rapid propagation seedling method

[0038] From 2009 to 2010, three methods of grafting, cutting and burying were used to conduct asexual reproduction experiments at the same time, repeated for 2 years, and the survival rates of grafting, cutting and burying were 67.7%, 9.1%, and 99.8% respectively in 2009; in 2010 Years were 56.9%, 10.2%, and 99.3%. The two averages were 62.3%, 9.7%, and 99.6%, respectively. The vegetative reproduction coefficient of the 2-year-old mother plant was very different among the three methods, among which the grafting method was 6.5 on average, the cutting method was 0.8, and the planting method was 14.9. And compared with the grafting method, the embedding method does not need to cultivate rootstocks, has low cost, short breeding cycle, high propagation coefficient and fast speed. Compared with the cutting method, the embedding method does not require special inserting beds and special inserting...

Abstract

The invention discloses a smoke tree rapid asexual propagation and breeding method. The smoke tree or common smoke tree rapid asexual propagation and breeding method includes the following steps of soaking annual non-bent sprays of a smoke tree or a common smoke tree into a naphthylacetic acid solution or an indolebutyric acid solution or a number six ABT rooting powder solution to obtain branches which are processed through hormones. The smoke tree rapid asexual propagation and breeding method has the advantages of being high in survival rate, high in propagation coefficient, less in expense, low in cost, large in emerge amount in the unit area, and the like.

Description

technical field [0001] The invention relates to a method for rapidly and asexually breeding seedlings of sumac cotinus. Background technique [0002] Zixia cotinus (Cotinus coggygria'Zixia') is a new variety of cotinus coggygria selected and bred in Beijing. It is a deciduous shrub with a height of 2-5m; the young branches are densely pilose, and the internodes are 2-4cm long; the leaves are obovate and 3-4cm long. 8cm, 3-8cm wide. Leaf blade densely pilose on both sides, 8-10 pairs of lateral veins, petiole densely pilose, 2-7cm long. The color of the new leaves at the top of the branches is purple red, the leaves are purple red throughout the year, the color becomes darker in summer, and the leaf color turns purple again in autumn; the panicle is terminal, densely pilose, and the small pedicel is 8-10mm long. The flowers are small, yellow-green; the drupe is small, flat-reniform, 3-4mm long, purple-red when mature, and brown when dry; blooms twice a year, and the first f...
