Abstract
The invention relates to a microbiota decussata cutting propagation method. The invention belongs to the technical field of plant propagation. The method comprises the steps that: (1) an appropriate propagation field is selected; (2) a groundmass is prepared; (3) spick cutting is carried out, such that cutting twigs are obtained; (4) a cutting treatment is carried out; (5) an arch shed is constructed; (6) a watering treatment is carried out 8-12 days after cutting; and (7) an acclimatizing treatment is carried out 55-65 days after cutting. According to the invention, microbiota decussata is propagated with the cutting method. A rooting situation is good, and a yield is higher than 90%. The propagation method is advantaged in simple operation and high propagation speed. The method is suitable for the climate and soil environment in our nation, and has a good market prospect.
Description
technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a cutting propagation method for Russian cypress. Background technique [0002] Russian cypress Microbiota decussata , Cupressaceae, Russian cypress, evergreen coniferous tree, low shrub on the ground, creeping extension, bark tan peeling off; tree height 20.0cm-40.5cm, crown width 1.2m-1.8m, short branches, slightly Flat, soft, feather-like, slightly drooping tip, with short and smooth whorled needles; scale leaves are tiny, nearly triangular, arranged in imbricate tiles, green in spring, green in summer, dark green in summer, and copper in autumn, until In winter, all of them turn purple, bronze or reddish-brown; in summer, both male and female cones are born on the top of short branches, the female cones are ovoid, with 3-4 scales, only one is fertile, and the cones are oval shape, tan. [0003] Russian Boxiguang can grow normally under full sun and ha...
