Problems solved by technology

There have been some studies on the cutting propagation technology of Melaleuca alternifolia, but due to the different cutting conditions and environments, the rooting survival rate is not stable enough, and the effect is not ideal.
Moreover, the root system of Melaleuca alternifolia cutting seedlings is not well developed, and the survival rate of cuttings usually creates a certain "illusion", that is, the branches are alive on the surface, but there is no rooting or less rooting under the substantive branches. Seedlings are also prone to death when transplanting

Embodiment 1

[0028] Nanning, in November, in the seedling greenhouse, put the cutting substrate into a transparent plastic bag with a diameter of 7cm and a height of 11cm. The day before the cutting, soak the cutting substrate twice with 0.5% potassium permanganate solution, and then rinse with clean water. Rinse well; the material parts by weight of the cutting substrate are: 5 parts of red heart soil and 1 part of plant ash. The preparation method is to crush the red heart soil with a 100-mesh sieve first, add plant ash and mix evenly to obtain the cutting substrate ; select the excellent tree felling piles with strong growth and no diseases and insect pests to deal with, and the semi-lignified bud strips with a diameter of 0.156 ~ 0.158cm in the current year are used as cuttings. The pruning length of the cuttings is 8-10cm, the side branches on both sides of the cuttings are kept 0.9-1cm, the leaves on both sides of the cuttings are 0.5-6cm, the lower end of the cuttings is cut into a p...

Embodiment 2

[0030] Nanning, in January, in the seedling greenhouse, put the cutting substrate into a transparent plastic bag with a diameter of 7cm and a height of 11cm. The day before the cutting, soak the cutting substrate twice with 0.3% potassium permanganate solution, and then rinse with clean water. Rinse well. The material parts by weight of the cutting substrate are: 5 parts of red heart soil and 1 part of plant ash. The preparation method is to first crush the red heart soil with a crusher and then pass through a 90-mesh sieve, add plant ash and mix evenly to obtain the cutting substrate. Select an excellent tree with strong growth and no diseases and insect pests as the mother plant, and collect semi-lignified tender branches with a diameter of 0.181-0.197 cm in the current year as cuttings. The pruning length of the cuttings is 9-12cm, the side branches on both sides of the cuttings are kept 0.7-0.8cm, the leaves on both sides of the cuttings are 0.7-0.8cm, the lower end of the...

Embodiment 3

[0032]Nanning, in May, in the seedling greenhouse, put the cutting substrate into a transparent plastic bag with a diameter of 7cm and a height of 11cm. The day before the cutting, soak the cutting substrate twice with 0.5% potassium permanganate solution, and then rinse it with clean water. Rinse well. The material parts by weight of the cutting substrate are: 5 parts of red heart soil and 1 part of plant ash. The preparation method is to first crush the red heart soil with a crusher and pass through an 80-mesh sieve, add plant ash and mix evenly to obtain the cutting substrate. Select the excellent trees with strong growth and no diseases and insect pests as the semi-lignified twigs with a diameter of 0.16-0.191 cm in the current year as cuttings. The pruning length of the cuttings is 8cm, the side branches on both sides of the cuttings are kept 0.5-0.6cm, the leaves on both sides of the cuttings are 0.8cm, the lower end of the cuttings is cut into a plane, and the distance ...

Abstract

The invention discloses a melaleuca alternifolia cutting propagation method. Red soil and plant ash are taken as cutting media which are loose, breathable and efficient in fertility, thereby being beneficial to rooting and sprouting of shoots for cutting; 0.5-2% of melaleuca oil is added into rooting agent, and has the effect of disease and pest prevention; chitin and glycerin are added into root dipping pulp, and certain antibacterial and water retention effect is achieved; cuttings take roots in 28-35 days, root systems grow robustly, the average survival rate of rooting is over 95% and is up to 98%, current-year semi-lignified twigs or stump-treated semi-lignified shoots with the diameter being 0.156-0.197cm are selected as shoots for cutting, shoots for cutting can be obtained more easily in a cutting orchard under the same condition, propagation efficiency is improved, a large number of melaleuca alternifolia nursery stocks can be obtained within a short period, massive seedling culture is facilitated, and fine properties of female parents are better maintained.

Description

technical field [0001] The invention belongs to the technical field of tree seedling cultivation, and in particular relates to a cutting propagation method of Melaleuca alternifolia. Background technique [0002] Melaleuca alternifolia ( Melaleuca alternifolia ), also known as tea oil tree, belongs to Myrtaceae (Myrtaceae) Melaleuca ( Melaleuca. ), native to the coastal areas of 23.5° south latitude of Australia and the northern part of the Northern Territory, its branches, leaves and trunks are rich in aromatic oil, that is, tea tree oil (Tea Tree Oil), which is a powerful antibacterial agent and immune stimulator , is widely used in industries such as spices, daily chemicals, medicine and food, and has extremely high economic value, and is called Australian gold. At present, the important value of Melaleuca alternifolia has been widely concerned by the chemical industry at home and abroad, and it has been successfully introduced and cultivated in Guangdong, Guangxi, Fuj...
