Cuttage propagation method for juniperus chinensis 'Pfitzeriana Aurea'

Abstract

The invention belongs to the technical field of plant propagation, and in particular relates to a cuttage propagation method for juniperus chinensis 'Pfitzeriana Aurea'. The cuttage propagation method comprises the following steps of: 1) selecting a propagation area, and establishing a cutting orchard of a juniperus chinensis 'Pfitzeriana Aurea' female parent area; 2) mixing peat, coconut husk, vermiculite and yellow subsoil which serve as matrixes in a volume ratio of (3-5):(2-4):(0.5-2):(1-3) uniformly, and filling into a 72-hole disc; 3) shearing spikes of an autumn tip in the previous year from a lateral branch of the parent in the first ten days of March; 4) infusing roots of cuttage branches formed by cutting the spikes in 1,400 to 1,600 ppm of No.6 sensheng plant rooting agent for 2 seconds; 5) erecting an arch shed, and covering by a plastic film; and 6) after 120 days, removing the film when a rooting rate is about 90 percent. By the cuttage propagation method for the juniperus chinensis 'Pfitzeriana Aurea', a rooting condition is good, and yield is over 90 percent; when the method is used, the juniperus chinensis 'Pfitzeriana Aurea' easily propagates and propagation speed is high; and the juniperus chinensis 'Pfitzeriana Aurea can adapt to the climate soil environment of China and has a good market prospect.

Description

Technical field [0001] The invention is a plant reproduction technology field, which is specifically a golden cypress cuttance breeding method. Background technique [0002] ‘Gold’ Belle Juniperus Chinesesis 'PFITZERIANA AUREA', belongs to the belonging to cypress, evergreen needles, paved short shrubs, red-brown bark, and branches from the nodes below the main trunk.The crown width is 1.5m-3.0m; coniferous and scale leaves are usually concentrated on the top. The scales are often accompanied by resin, the old leaves are bright green, and the top of the new leaves is golden, with fragrance.The fruit pulp-shaped gray is very small, often hidden in the leaves, from 10th to November.Hi Guang, good drainage soil, slightly acidic, neutral, and microbium soil can grow, and grow rapidly. It can be formed naturally. [0003] Golden cypress is native to China, drought -resistant and anti -air pollution. It is currently widely planted in North America. It is mostly used in plants and fence...
