Embodiment 1

[0029] This embodiment is implemented in the Songlinpo area of ​​Jianshan Mountain in Shangzhai, Luzhang Town.

[0030] First, select medium-thick soil with a pH value of 5.5 at an altitude of 1,500 meters. After deep plowing and leveling, dig a 40 cm x 40 cm x 40 cm seedling bed and apply 525 t / mu of farmyard manure as base fertilizer. In March, after raising the yew with a height of 20-30 cm, first soak the roots of the seedlings in the thin mud mixed with yellow sand, humus and water in a ratio of 3.5:1:1.5 for 3 minutes. , and then plant the seedlings in the seedling border, and interplant them in the three-dimensional growth environment where the upper wood is Yunnan pine and the surface plants are Drichoptera, interplant two rows of yew between every two rows of pine, and interplant between two rows of yew A row of ferns. The row spacing of yew is 80 cm, the plant spacing is 50 cm, the row spacing between yew and Yunnan pine is 100 cm, the plant spacing of Yunnan pine i...

Embodiment 2

[0032] This embodiment is implemented in the Songlinpo area of ​​Jianshan Mountain in Shangzhai, Luzhang Town.

[0033] Firstly, choose medium-thick soil with a pH value of 6 at an altitude of 1,700 meters. After deep plowing and leveling, dig a 30 cm x 30 cm x 30 cm seedling bed and apply 630 t / mu of farmyard manure as base fertilizer. In March, after raising the yew with a height of 20-30 cm, first soak the roots of the seedlings in the thin mud mixed with yellow sand, humus and water in a ratio of 3:1:2 for 4 minutes. , and then plant the seedlings in the seedling border, and interplant them in the three-dimensional growth environment where the upper wood is Simao pine and the surface plants are Asplenium fern, interplant two rows of yew between every two rows of pine, and interplant between two rows of yew A row of ferns. The row spacing of yew is 85 cm, the row spacing is 55 cm, the row spacing between yew and Simao pine is 110 cm, the row spacing of Simao pine is 170 cm...

Embodiment 3

[0035] This embodiment is implemented in the Songlinpo area of ​​Jianshan Mountain in Shangzhai, Luzhang Town.

[0036] Firstly, choose medium-thick soil with a pH value of 7 at an altitude of 1900 meters. After deep plowing and leveling, dig a 50 cm x 50 cm x 50 cm seedling bed and apply 750 t / mu of farmyard manure as base fertilizer. In April, after raising the yew with a height of 20-30 cm, first soak the roots of the seedlings in the thin mud mixed with yellow sand, humus and water at a ratio of 2.5:1:2.5 for 5 minutes. , and then plant the seedlings in the seedling border, and interplant them in the three-dimensional growth environment where the upper wood is Pinus massoniana and the surface plants are Pteris fern, interplant two rows of yew between every two rows of pines, and interplant between two rows of yews A row of ferns. The row spacing of yew is 90 cm, the row spacing is 60 cm, the row spacing between yew and masson pine is 120 cm, the row spacing of masson pin...

Abstract

The invention discloses a three-dimensional cultivation method for interplanting yew, pine and fern, which comprises the steps of site preparation, transplanting and interplanting, field management and the like. Select an altitude section of 1600-2500m, medium-thick soil with neutral to weak acidity, dig seedling plots, and apply base fertilizer. After raising the yew seedlings, soak the roots of the seedlings in the thin mud mixed with organic fertilizer, and then interplant them in a three-dimensional growth environment where the upper wood is pine and the surface plants are ferns, interplanting between every two rows of pine Two rows of yews, interplant a row of ferns between the two rows of yews. The row spacing of yew is 80~90cm, the row spacing of yew is 50~60cm, the row spacing between yew and pines is 100~120cm, and the row spacing of pine is 160~180cm. After the yew seedlings are transplanted and interplanted, weeding and soil cultivation are carried out 3 to 5 times a year, topdressing is done 2 to 3 times, and pine seedlings are topdressed once. Tests have proved that: according to the interplanting method of the present invention, the survival rate, growth rate and seed setting rate of the yew seedlings can be greatly improved, and the growth rate is fast and the fruit is early, which is suitable for popularizing and planting in a large area.

Description

technical field [0001] The invention belongs to the technical field of arboriculture, and in particular relates to a three-dimensional cultivation method for interplanting of yew, pines and ferns, which can greatly improve the survival rate, growth rate and seed setting rate of yew transplanting. Background technique [0002] The species of the genus Taxus in the family Taxaceae are large evergreen trees, and five of them are national first-class key protected plants. The active substance has high medicinal development value. However, the development of the anticancer drug paclitaxel has led to the predatory destruction of the natural resources of this plant. In order to protect the precious species resources of Taxus and ensure the sufficient, stable and balanced supply of Taxol, Taxus should be actively cultivated Plantation resources. [0003] However, in the southern provinces, due to the high temperature and low rainfall in summer, the yew seedlings are exposed to the...
