Embodiment 1

[0019] In March 2016, in the nursery of the Flower Institute of Guangxi Academy of Forestry, Nanning City, 10 bamboo and cypress green seedlings with a height of more than 300cm and a diameter of more than 6cm were selected as rootstocks, and all side branches below 200cm on the main trunk were cut off. On March 25, 2016, on the excellent mother tree of Podocarpus nakaii Hayata in Taiwan, strong branches of 1-2 years old were selected and cut into 8-10cm long scions, with 2-3 small branches in the middle and upper parts of the scion , the lower part is cut into a wedge shape; at the place where the bamboo and cypress rootstock is 150-200 cm above the ground and the bark is smooth, use a grafting knife to cut out a "T"-shaped incision, reaching the xylem; insert the scion, use electrical tape to wrap the grafting joint and seal it, and Cover the scion with a plastic bag and tie the mouth of the bag tightly. Each seedling was grafted with 4 to 6 scions, and 10 seedlings were gra...

Embodiment 2

[0021] In April 2016, in the nursery of the Flower Institute of Guangxi Academy of Forestry, Nanning City, 10 bamboo and cypress green seedlings with a height of more than 300cm and a diameter of more than 6cm were selected as rootstocks, and all side branches below 200cm on the main trunk were cut off. On April 10, 2016, on the excellent mother tree of Podocarpus wangii C.C.Chang, 1-2 years old strong branches were selected and cut into 8-10cm long scions with 2-3 small branches in the middle and upper part of the scion. Cut the lower part into a wedge shape; use a grafting knife to cut a "T"-shaped incision at the place where the bamboo and cypress rootstock is 150 to 200 cm above the ground and the bark is smooth, reaching as deep as the xylem; insert the scion, use electrical tape to wrap and seal the grafting joint, and Put a plastic bag on the scion and tie the mouth of the bag tightly. Each seedling was grafted with 3 to 6 scions, and 10 seedlings were grafted with 50 s...

Embodiment 3

[0023] In May 2016, at the Lalang Forest Farm in Guangxi, Hechi City, 10 bamboo and cypress green seedlings with a height of more than 300cm and a DBH of more than 6cm were selected as rootstocks, and all side branches below 200cm on the main trunk were cut off. On May 5, 2016, on the excellent mother tree of Podocarpus macrophyllus (Thunberg) Sweet, select 1-2 years old strong branches and cut them into 8-10cm long scions with 2-3 small scions in the middle and upper part of the scion. For branches, cut the lower part into a wedge shape; use a grafting knife to cut a "T"-shaped incision at the place where the bamboo cypress rootstock is 150-200 cm above the ground and the bark is smooth, reaching as deep as the xylem; insert the scion, and use electrical tape to wrap and seal the grafting joint. And put a plastic bag on the scion, and tie the mouth of the bag tightly. Each seedling was grafted with 2 to 6 scions, and 10 seedlings were grafted with 50 scions in total. About 3...

Abstract

The invention discloses a method for cultivating a compound landscape tree of Nagera Gaertner and Podocarpus L' Heritier ex Persoon. The method adopts a Podocarpus plants as scions and green Nageia Gaertner seedlings as rootstocks, a bark-inserted type side grafting method is adopted, and the compound Nagera Gaertner landscape tree with Podocarpus branches and leaves is cultivated through selection of the Nageia Gaertner seedlings, preparation of the Podocarpus scions, grafting, subsequent management and other steps. The method is simple and easy to implement, and has a grafting survival rateof 90% or above, the ornamental value and economic value of the green Nageia Gaertner seedlings can be improved, and a new way is provided for cultivation of the Nageia Gaertner tree.

Description

technical field [0001] The invention belongs to the technical field of woody plant cultivation, and relates to a method for cultivating a composite landscape tree of bamboo cypress and podocarpus pine. 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 kinship. Therefore, Flora of China ("Chinese Plants "Revised English Edition of Zhi" clearly divides the two into two different genera. [0003] Podocarpus macrophyllus (Thunberg) Sweet, Taiwan Podocarpus nakaii Hayata and Podocarpus wangii C.C.Chang are well-known ornamental plants, often used in landscaping and bonsai production. In order to enhance the ornamental value, the Podocarpus plants can adjust the tree shape by grafting. Most of the grafting uses the common species of Podocarpus macrophyllus (Thunberg) Sweet as the rootstock, and its same genus or species as the scion source...
