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 pine, and interplant between two rows of yew 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 pine ...

Abstract

The invention discloses a three-dimensional interplanting method of Chinese yew, conifer and fern. The method includes the steps of soil preparation, transplantation and interplantation, field management and the like. Particularly, the method includes selecting neutral to acidic medium-layer thick soil at an altitude of 1600-2500m, digging seedling beds and applying base fertilizer; and after the Chinese yew is lifted, submerging the seedling root of the Chinese yew into mud mixed with organic fertilizer, and then interplanting the Chinese yew into a three-dimensional growing environment in which the upper-layer vegetation is the conifer and the ground vegetation is the fern, wherein two rows of the Chinese yew are interplanted between every two rows of the conifer, and a row of the fern is interplanted between every two rows of the Chinese yew. The row distance of the Chinese yew is 80-90cm, the inter-plant distance of the Chinese jew is 50-60cm, the row distance between the Chinese row and the conifer is 100-120cm, and the inter-plant distance of the conifer is 160-180cm. After the Chinese yew is transplanted and interplanted, the weeding and earthing-up should be implemented 3-5 times a year, the topdressing should be implemented 2-3 times a year, and the topdressing of the conifer seedlings should be implemented once a year. Experiments prove that according to the three-dimensional interplanting method of the Chinese yew, the conifer and the fern, the survival rate, the growth rate and the setting rate of the Chinese yew are improved greatly, and meanwhile, fast growth, early fruit bearing and capability of large-area popularization and plantation can be obtained.

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...
