Embodiment 1

[0020] In March 2015, container seedlings of Podocarpusnakaii Hayata were propagated by cuttings in the nursery of the Flower Institute of Guangxi Academy of Forestry, Nanning. On March 16, 2016, 30 qualified Podocarpus container seedlings were moved to the base of qualified bamboo and cypress rootstock seedlings, placed close to each other and carried out one-to-one intergeneric grafting; 45 days after grafting, the first time Check, the joint is obviously raised, cut the Podocarpus container seedlings below the joint, and cut the bamboo and cypress rootstock seedlings above the joint; after the second investigation 30 days after cutting the anvil, 29 grafted seedlings survived, with a survival rate of 96.6%. Subsequently, the grafted Podocarpus seedlings were managed normally; the container seedlings of Podocarpus were strengthened with water, fertilizer and pruning management to promote the growth of new trunks; the third survey in December 2016 finally obtained 29 1-year-ol...

Embodiment 2

[0022] In April 2015, container seedlings of Podocarpus macrophyllus (Thunberg) Sweet were propagated by cuttings in Lalang Forest Farm, Guangxi, Hechi City. On April 5, 2016, 30 container seedlings of Podocarpus meeting the requirements were moved to the base of the rootstock seedlings of bamboo and cypress, placed close to each other and grafted one-to-one. The first time after 45 days of grafting Check, the joint is obviously raised, cut the Podocarpus container seedlings below the joint, and cut the bamboo and cypress rootstock seedlings above the joint; the second investigation 30 days after cutting the anvil, the survival rate reached 100%. Subsequently, the grafted Podocarpus seedlings were managed normally; water, fertilizer and pruning management was strengthened for Podocarpus container seedlings to promote the growth of new trunks; the third survey in December 2016 finally obtained 30 1-year-old Podocarpus grafted seedlings and 30 2-year-old Podocarpus container see...

Embodiment 3

[0024] In March 2016, container seedlings of Podocarpuswangii C.C.Chang were propagated by cuttings in the nursery of the Flower Institute of Guangxi Academy of Forestry, Nanning. On April 15, 2017, 20 qualified Podocarpus microphylla seedlings were moved to the base of qualified bamboo and cypress rootstock seedlings, placed close to each other and carried out one-to-one intergeneric grafting; 45 days after grafting, the first In the first inspection, the joint was obviously raised, and the container seedlings of Podocarpus lobata were cut below the joint, and the bamboo and cypress rootstock seedlings were cut above the joint; in the second investigation 30 days after the cutting, 19 plants survived grafting, with a survival rate of 95%. Subsequently, the grafted Podocarpus seedlings were managed normally; the container seedlings of Podocarpus were strengthened with water, fertilizer and pruning management to promote the growth of new trunks; the third survey in November 2017...

Abstract

The invention discloses an intergeneric grafting propagation method of podocarpus plants. The method comprises the steps that podocarpus nagi seedlings are used as stocks, container seedlings of the podocarpus plants are used as scion sources, and by adopting an approach grafting method, through the steps of selection of podocarpus nagi stock seedlings, selection of podocarpus container seedlings,grafting, following management and the like, podocarpus seedlings are propagated. The intergeneric grafting propagation method of the podocarpus plants is simple and easy to achieve, the survival rate of grafting is up to 95% or above, a novel method for grafting propagation of the podocarpus plants is provided, and the application of the podocarpus nagi seedlings can also be enlarged.

Description

technical field [0001] The invention belongs to the technical field of woody plant propagation, and relates to a method for intergenus grafting and propagation of Podocarpus plants. Background technique [0002] Both Podocarpus L’Heritier ex Persoon and Nageia Gaertner belong to the Podocarpaceae Endlicher family, but they have large morphological differences and distant relationship. Therefore, in "Flora of China" (English revised edition of "Flora of China"), the two have been clearly divided into two different genera. [0003] Podocarpus macrophyllus (Thunberg) Sweet, Podocarpus nakaii Hayata and Podocarpus wangii C.C.Chang are well-known ornamental plants, often used in landscaping and bonsai production, with a large market demand and sales The price is higher. However, Taiwan Podocarpus pine, small-leaved Podocarpus pine, and some fine varieties of Podocarpus pine have relatively small distribution ranges, few propagation materials, and high seedling cost. Plants of ...
