Embodiment 1

[0016] A cultivation method of Podocarpus pine, comprising the following steps:

[0017] (1) Cultivate the Podocarpus pine sapling that trunk diameter 1.5cm is used for grafting;

[0018] (2) the Podocarpus pine trunk that the tree diameter meets the expectation requirement is cut into sections, and the two ends are sawed flat to make the rootstock trunk;

[0019] (3) Grafting tree roots: The grafting time is selected so that the growth period of the tree is longer than 6 months. First, more than two longitudinal wedge-shaped long mouths are opened at the lower end of the cut rootstock trunk, and the longitudinal wedge-shaped long mouths expose the xylem. The depth of the longitudinal wedge-shaped long mouths It is 60% of the diameter of the Podocarpus saplings used for grafting, and the external width of the longitudinal wedge-shaped long mouth is 73% of the diameter of the Podocarpus saplings used for grafting. For the root system of pine saplings, cut off the main trunk an...

Embodiment 2

[0024] A cultivation method of Podocarpus pine, comprising the following steps:

[0025] (1) Cultivate the Podocarpus pine sapling that trunk diameter 1.7cm is used for grafting;

[0026] (2) the Podocarpus pine trunk that the tree diameter meets the expectation requirement is cut into sections, and the two ends are sawed flat to make the rootstock trunk;

[0027] (3) Grafting tree roots: The grafting time is selected so that the growth period of the tree is longer than 6 months. First, more than two longitudinal wedge-shaped long mouths are opened at the lower end of the cut rootstock trunk, and the longitudinal wedge-shaped long mouths expose the xylem. The depth of the longitudinal wedge-shaped long mouths It is 65% of the diameter of the Podocarpus saplings used for grafting, and the external width of the longitudinal wedge-shaped long mouth is 75% of the diameter of the Podocarpus saplings used for grafting. For the root system of pine saplings, cut off the main trunk an...

Embodiment 3

[0032] A cultivation method of Podocarpus pine, comprising the following steps:

[0033] (1) Cultivate the Podocarpus pine seedling that trunk diameter 1.6cm is used for grafting;

[0034] (2) the Podocarpus pine trunk that the tree diameter meets the expectation requirement is cut into sections, and the two ends are sawed flat to make the rootstock trunk;

[0035] (3) Grafting tree roots: The grafting time is selected so that the growth period of the tree is longer than 6 months. First, more than two longitudinal wedge-shaped long mouths are opened at the lower end of the cut rootstock trunk, and the longitudinal wedge-shaped long mouths expose the xylem. The depth of the longitudinal wedge-shaped long mouths It is 63% of the diameter of the Podocarpus saplings used for grafting, and the external width of the longitudinal wedge-shaped long mouth is 74% of the diameter of the Podocarpus saplings used for grafting. For the root system of pine saplings, cut off the main trunk a...

Abstract

The invention discloses a cultivation method of podocarpus macrophylla. The method comprises: cultivating podocarpus macrophylla seedlings with a trunk diameter of 1.5 to 1.7 cm for grafting; cuttingthe podocarpus macrophylla seedlings with the trunk diameter satisfying requirements into segments and sawing two ends of the segments into flat surfaces, and using the segments as stock trunks; grafting roots; applying a layer of wound coating agent to both ends of each stock trunk and grafting sites; and winding a protective film around a position 25-28 cm from the top of each stock trunk; setting up a shadehouse and conducting daily cultivation management; and half a year after planting, removing the protective film, removing the shadehouse, and conducting daily cultivation management. According to the method, the roots of podocarpus macrophylla are grafted onto the podocarpus macrophylla stock trunks; and the stock trunks grafted with the roots are planted in soil to form new branchesto form a trees with large diameter; one large tree can be formed into a plurality of large trees, save large tree resources and achieve the purpose of rapidly cultivating large trees.

Description

technical field [0001] The invention relates to a method for cultivating Podocarpus pine. Background technique [0002] At present, with the continuous progress of society, the urbanization process is accelerating, and people's material and cultural levels are also improving. Various garden constructions in urbanization construction have been favored by the public, and garden construction mainly relies on various An ornamental tree. It takes decades or even hundreds of years for various trees in nature to grow to form its unique ornamental value and value. Existing plant trees with ornamental value are few and far between, extremely rare and extremely expensive. Furthermore, these rare ornamental plants all grow in remote areas, not where people need them most. In order to solve actual or potential environmental problems, coordinate the relationship between human beings and the environment, and ensure sustainable economic and social development, countries around the world...
