Embodiment 1

[0035] The excellent clones of Chinese fir tree seedlings are planted in a mother plant incubator with a diameter of 15 cm and a height of 15 cm equipped with a mother plant substrate to cultivate the mother plant for ear picking. Place it on a non-woven fabric with a thickness of 0.1-0.2cm. The components and parts by weight of the mother plant substrate are: 7 parts of yellow heart soil, 2 parts of decomposed wood bran, and 1 part of decomposed oyster mushroom residue. For mother plants with a ground diameter of 0.5-1.0 cm, cut off the trunk at 5-10 cm at the base, and topdress and spray hormones to promote germination according to conventional methods.

[0036] Choose a leeward, sunny place with good water permeability to build an open-air cutting bed. The length and width of the cutting bed are 10 m×1 m, and the cutting bed is made of stones as the bottom. Use sifted fresh yellow heart soil as the cutting substrate, put the cutting substrate into a nutrient bag of 8cm×12c...

Embodiment 2

[0040]The excellent clones of Chinese fir tree seedlings are planted in a mother plant incubator with a diameter of 15 cm and a height of 20 cm equipped with a mother plant substrate to cultivate the ear-picking mother plants. Place it on a non-woven fabric with a thickness of 0.1-0.2cm. The components and parts by weight of the mother plant substrate are: 7 parts of yellow heart soil, 2 parts of decomposed coconut peat, and 1 part of decomposed oyster mushroom dregs. For mother plants with a ground diameter of 0.5-0.8 cm, cut off the trunk at 5-8 cm at the base, and topdress and spray hormones to promote germination according to conventional methods.

[0041] Choose a leeward sunny place with good water permeability to build an open-air cutting bed. The length and width of the cutting bed are 10 m×1.2 m, and the cutting bed is made of stones as the bottom. Use sifted fresh yellow heart soil as the cutting substrate, put the cutting substrate into a nutrient bag of 8cm×12cm, ...

Embodiment 3

[0045] Plant the good clones of Chinese fir seedlings in a mother plant incubator with a diameter of 20 cm and a height of 15 cm to cultivate the ear-picking mother plants. Place it on a non-woven fabric with a thickness of 0.1-0.2cm. The components and parts by weight of the mother plant substrate are: 7 parts of forest topsoil, 2 parts of decomposed wood, and 1 part of decomposed oyster mushroom residue. For mother plants with a ground diameter of 0.8-1.0 cm, cut off the trunk at 8-10 cm at the base, and topdress and spray hormones to promote germination according to conventional methods.

[0046] Choose a leeward sunny place with good water permeability to build an open-air cutting bed. The length and width of the cutting bed are 20 m×1 m, and the cutting bed is made of coarse sand as the bottom. Use sifted fresh yellow heart soil as the cutting substrate, put the cutting substrate into a nutrient bag of 8cm×12cm, and place it tightly in the cutting bed; sterilize the subs...

Abstract

The invention discloses a seedling growing method of tender branch cutting for keteleeria cyclolepis flous. The seedling growing method of tender branch cutting comprises the steps of cultivating a scion mother tree, cutting out trunks to promote new shoot, preparing a cutting bed, gathering and processing cutting slips, carrying out cuttage and management procedures after the cuttage. The scion mother tree is cultivated and obtained through a container seedling growing method and a procedure of new shoot promotion after cutting off trunks. Cutting slips for cuttage are obtained by collecting coppice shoots born by the mother plant in current year or one year after, and then the cutting slips are transplanted to a prepared cutting bed provided with a cuttage substrate, and finally the cuttage seedlings of the keteleeria cyclolepis flous are obtained through management procedures after the cuttage. The seedling growing method of tender branch cutting for keteleeria cyclolepis flous adopts twigs of the keteleeria cyclolepis flous as cuttage breeding seedlings, breaks through a technical bottleneck that the cuttage seedling of the keteleeria cyclolepis flous has difficulty in taking root. Compared with planting seedlings, the early growth speed of the cuttage seedlings after being planted increases obviously, and can maintain good characteristics of fine strains. Besides, the seedling growing method of tender branch cutting for keteleeria cyclolepis flous has good economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a seedling raising method of twig cuttings of Chinese fir. Background technique [0002] Jiangnan oil cedar (Keteleeria cyclolepis) is a variant of Keteleeria fortuneivar.fortunei (A.Murray bis) Carriere. one. Jiangnan oil fir is an evergreen tree with straight wood texture, fine structure, solid material, beautiful pattern, impregnation resistance, wide application, fast growth and strong adaptability. Mainly distributed in Fujian, Zhejiang, Jiangxi, Guangdong, Guangxi, Hunan, Guizhou, Yunnan and other places. [0003] At present, the Jiangnan oil fir is mainly afforested with seedlings. Due to the unstable seed yield and poor collection of Yale fir, it is far from meeting people's needs for afforestation of Yale fir. Therefore, there is an urgent need to strengthen the research on the development and utilization of the resources of Yale fir and seedlings ...
