Cuttage propagation method of Virginia oak

Abstract

The invention relates to a cuttage propagation method of Virginia oak, which belongs to the technical field of plant cultivation. The method comprises the following steps: firstly, a sterilizing seedbed is built in a big-arch shelter, an arch shed is built on the seedbed, a hole pan provided with cuttage substrate is arranged in the seedbed, and the cuttage substrate is treated and sets aside; secondly, branches derived from close roots of the Virginia oaks grown for 2-4 years are selected to prune ears in February to March every year when sprouts do not and are about to burgeon, and the ear strips are pruned into branches; thirdly, the branches are treated by root stimulating agent, and the cuttage is done immediately, for the branches which then enter into the management after the cuttage; fourthly, after more than 70 percent of branches root and sprout, the hole pan is moved to forcibly exercise the plantlets outside the big-arch shelter, and the plants are transplanted into ground after being exercised for 30-35 days at the last third of the December or the last third of the February of the next year and enter the management after transplanting. The cuttage propagation adopting the method has high survival ratio and fast propagation speed. The invention is suitable for the climatic environments in most parts of Yangtze River Delta in China and has the survival ratio up to 80-90 percent, and the obtained nursery plantlets of the Virginia oaks have sound quality.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a cutting propagation method of oak oak. Background technique [0002] Quercus virginiana (Quercus virginiana) belongs to the Fagaceae (Fagaceae) Quercus species. It is an evergreen broad-leaved tall tree with single leaves, alternate, old leaves are leathery, the surface of the leaves is dark green and shiny, and the back is green and white. , shape, size, texture and other traits have strong plasticity with the influence of development stage and environment. New leaves are large and fleshy, light green in color, with large and few leaf margin teeth; old leaves are small and leathery, and leaf margin teeth are small and thick. many. It blooms in early spring, the flowers are yellow, and the mature fruit is brown. It is commonly known as acorn, which provides a rich source of food for birds and animals. It falls after maturity, and the seeds have low vigor....
