Embodiment 1

[0022] (1) Cutting substrate selection: choose river sand as the main cutting substrate, and also include perlite and vermiculite, the weight ratio of the river sand, perlite and vermiculite is 2:1:1, and the thickness is 16cm;

[0023] (2) Selection of cuttings: the cuttings are selected from the semi-lignified branches of the year, the length is not limited, and the diameter of the cuttings is greater than 5mm;

[0024] (3) Cutting: cut each section, leave 1cm above the section, leave 0.5cm below the section, keep half of the blade, cut each section from the middle, and keep the complete bud, so that one section forms two buds;

[0025] (4) Cutting: Cutting the sprouts obtained in step (3) on the cutting substrate, the cutting depth is two-thirds of the length of the sprouts, and the temperature is 20°C, and the humidity is 80% for rooting.

Embodiment 2

[0027] (1) Cutting substrate selection: select river sand as the main cutting substrate, and also include perlite and vermiculite, the weight ratio of the river sand, perlite and vermiculite is 2:1:1, and the thickness is 20cm;

[0028] (2) Selection of cuttings: the cuttings are selected from the semi-lignified branches of the year, the length is not limited, and the diameter of the cuttings is greater than 5mm;

[0029] (3) Cutting: cut each section, leave 1cm above the section, leave 1cm below the section, keep half of the blade, cut each section from the middle, and keep the complete bud, so that one section forms two buds;

[0030] (4) Cutting: Carry out cutting on the cuttage matrix with the bud body obtained in step (3), the cutting depth is two-thirds of the bud body length, and the temperature is 30° C., and the humidity is 90% to take root.

Embodiment 3

[0032] (1) Cutting substrate selection: choose river sand as the main cutting substrate, and also include perlite and vermiculite, the weight ratio of the river sand, perlite and vermiculite is 2:1:1, and the thickness is 18cm;

[0033] (2) Selection of cuttings: the cuttings are selected from the semi-lignified branches of the year, the length is not limited, and the diameter of the cuttings is greater than 5mm;

[0034] (3) Cutting: cut each section, leave 1cm above the section, leave 0.8cm below the section, keep half of the blade, cut each section from the middle, and keep the complete bud, so that one section forms two buds;

[0035] (4) Cutting: Cutting the bud body obtained in step (3) on the cutting substrate, the cutting depth is two-thirds of the bud body length, and the temperature is 25° C., and the humidity is 85% to take root.

Abstract

The invention provides a hydrangea cuttage reproduction method which includes the steps of firstly, cuttage matrix selection; secondly, scion selection; thirdly, shearing; fourthly, cuttage. Compared with the prior art, the hydrangea cuttage reproduction method has the advantages of shortening hydrangea cultivation time of the prior art, more importantly, by the technology that two buds are distributed on each section, rooting time can be shortened evidently, rooting number and rate are increased greatly, reproduction yield is increased, and rooting agent use is reduced.

Description

technical field [0001] The invention relates to a cutting propagation method of hydrangea, which belongs to the field of asexual propagation of hydrangea. Background technique [0002] Hydrangea (scientific name: Hydrangea macrophylla), also known as hydrangea and hydrangea, is a plant of the genus Hydrangea in the saxifrage family. The Hydrangea flower is white and plump, large and beautiful, and its flower color can be red or blue, which is pleasing to the eye and refreshes the mind. It is a common potted ornamental flower and tree. The hydrangea was cultivated in China earlier, and the hydrangea was planted in the gardens in the south of the Yangtze River built in the Ming and Qing Dynasties. The parks built in the early 20th century are also inseparable from the planting of hydrangeas. Modern parks and scenic areas are planted in patches to form a landscape. [0003] There are many ways to propagate hydrangeas, such as branching, layering, cuttings and tissue culture,...
