Embodiment 1

[0053] (1) Preparation of substrate / cutting bed: Use perlite, vermiculite, and peat to prepare the cutting substrate at a ratio of 1:1:1. Put the cutting matrix in the planting tray, the thickness of the matrix is ​​about 12-16cm. Use 800 times of carbendazim solution to irrigate and disinfect the above substrate.

[0054] (2) Cutting treatment: In September, cut the semi-lignified branches of Xiaoketong that year to make cuttings, keep 2 nodes and half a leaf for each cutting, and cut off the rest of the leaves. After soaking the cuttings in the growth hormone solution for 1 hour, the cuttings were placed in the substrate prepared above. Growth hormone is prepared by mixing naphthaleneacetic acid and indole butyric acid at a ratio of 1:1, and the concentration of growth hormone solution is 100ppm. The cutting depth is 4.5-5.5cm, and the cutting spacing is 5cm*5cm.

[0055] (3) Post-planting management: place the cutting seedlings in a shaded environment at 15-20°C and 60-8...

Embodiment 2

[0059] This example is basically the same as the cutting propagation method described in Example 1, the main difference is that the growth hormone used in this example is prepared by mixing naphthalene acetic acid and indole butyric acid at a ratio of 1:1, and the concentration is 150ppm .

[0060] After the cuttage of Akebia in the present embodiment, its rooting rate was counted on the 90th day as 75%, the average number of roots was 6.4 / piece, and the average root length was 7.8cm. Its rooting situation is as follows figure 2 shown.

Embodiment 3

[0062] The present embodiment is basically the same as the cutting propagation method described in embodiment 1, the main difference is that each cutting ear of the present embodiment has 2 nodes. And in embodiment 1, each cutting ear keeps 1 node.

[0063] In the present embodiment, after the cuttage of Xiaoketong was cut, the rooting rate was 67% according to statistics on the 90th day, the average root length was 6.9cm, and the average rooting number of each cutting was 4.6 / piece. Rooting speed is slower than embodiment 1. Its rooting situation is as follows image 3 shown.

Abstract

The invention provides a cutting propagation method of clematis armandii. A proper clematis armandii cutting medium is found, a reasonable medium component proportion is set, by matching various cutting propagation details such as corresponding proper cutting depth, node number of cutting slips, leaf number, growth hormone with proper soaking concentration and components and the like, the rooting efficiency and survival rate are improved, the propagation efficiency of the clematis armandii is improved, the propagation yield of the clematis armandii is increased, the production cost is reduced, and the requirements of propagation production and landscape application of clematis armandii resources are met.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a cuttage propagation method of xiaoketong. Background technique [0002] Clematis Armandii, Clematis Armandii, Ranunculaceae Clematis, is an evergreen vine. Stems cylindrical, three compound leaves, leaves leathery, oblong-ovate. The flowering period is from March to April, in cymes, and the diameter of a single flower is about 2cm. Most of the flowers are milky white, occasionally light pink, and the flowers are large. The fruiting period is from April to July. Achenes are flat and sparsely white villous. Mainly distributed in Yunnan, Guizhou, Sichuan, Hubei, Hunan and other places. At present, it mainly relies on natural reproduction in the original place. [0003] Xiaomutong has a large amount of flowers and strong adaptability. It is an excellent early-flowering evergreen clematis at present. The market is scarce and needs to be popularized and appl...
