Embodiment 1

[0030] An interplanting method for improving the carbon sink capacity of Camellia oleifera forest, the steps are as follows:

[0031] (1) Forest land selection: In the Beixiang area of ​​Liuyang, Hunan, a barren hill with an open terrain, a slope of about 20°C and an altitude of about 300m was selected among the forest land owned by a camellia oleifera plantation professional cooperative;

[0032] (2) Land preparation to form a ladder: Remove surface vegetation, rocks, tree pockets and other sundries from the mountain, plow the bottom soil of the land and expose it to sunlight for 5 days, and then repair it along the slope with a width of 3m and a height difference of 1.5m between adjacent areas. Horizontally surround the mountain steps, and excavate a drainage ditch with a width of 18cm and a depth of 15cm inside the steps;

[0033] (3) Hole opening and fertilization: Excavate planting holes on the horizontal steps according to the specifications of plant spacing 1.0m, hole d...

Embodiment 2

[0044] An interplanting method for improving the carbon sink capacity of camellia oleifera forest, the steps of which are: 1) forest land selection, 2) land preparation to form ladders, 3) opening holes and fertilizing, 4) transplanting and planting, 5) ditching and drilling, 6) post-planting management , 7) cut green processing;

[0045] The transplanting and planting method is: a. Transplanting method: After reaching the planting period, select high-quality two-year-old Camellia oleifera grafted seedlings and three-year-old Jasmine jasmine self-growing seedlings and transplant them into the planting hole, cover with soil and fill them up, and pour enough root-fixing water , and in the pocket of the forest seedlings, mounds with high inside and low outside to prevent water accumulation at the roots; b. Mixed planting mode: Camellia oleifera seedlings and gardenia jasmine seedlings are placed on the steps according to "-tea-gardenia-gardenia-tea-gardenia -Gardenia-tea-" is pla...

Embodiment 3

[0049] An interplanting method for improving the carbon sink capacity of camellia oleifera forest, the steps of which are: 1) forest land selection, 2) land preparation to form ladders, 3) opening holes and fertilizing, 4) transplanting and planting, 5) ditching and drilling, 6) post-planting management , 7) cut green processing;

[0050] The transplanting and planting method is: a. Transplanting method: After reaching the planting period, select high-quality two-year-old Camellia oleifera grafted seedlings and three-year-old Jasmine jasmine self-growing seedlings and transplant them into the planting hole, cover with soil and fill them up, and pour enough root-fixing water , and in the pocket of the forest seedlings, mounds with high inside and low outside to prevent water accumulation at the roots; b.

Abstract

The invention discloses an interplanting method improving carbon sequestration capacity of tea-oil tree forest. The method comprises steps of (1) selecting a forest land, (2) preparing a land into a ladder, (3) digging holes and applying fertilization, (4) transplanting and planting the tea-oil trees, (5) performing trenching and sowing in drills, (6) performing management after the transplantation and (7) cutting away green bodies. According to natural lamination of different plants at individual vertical height and demands for water and fertility as well as management, crops suitable for being interplanted in an artificial tea-oil trees are selected and a stereoscopic interplanting mode is formed; forest land vegetation coverage is improved and photosynthetic fixed carbon content of the whole forest land ecological system can be obviously improved; further litter carbon input amount, soil structure and environment conditions can be changed; and forest land carbon sequestration capacity can be enhanced. Besides, with the implementation of the interplanting method, deficiencies of non-output during a tea-oil young tree stage can be overcome and management cost of the forest land can be improved; afforestation economic benefits can be improved and forest land spicy variety can be increased; tea-oil tree micro-climate can be improved; water and soil loss during the young tree stage can be reduced; and water storage and soil moisture conservation can be improved; and obvious ecological benefits can be achieved.

Description

technical field [0001] The invention relates to the technical field of economic forest planting, in particular to an interplanting method for improving the carbon sink capacity of camellia oleifera forest. Background technique [0002] Camellia oleifera is one of the four major woody oil plants in the world. It grows in the mountains and hills in the subtropical regions of southern my country, mainly in Zhejiang, Jiangxi, Hunan, Guangxi, Guangdong, Hubei and other provinces. The unsaturated fatty acid content of camellia oil is as high as 90%, which is much higher than that of vegetable oil, peanut oil and soybean oil, and the content of vitamin E is twice as high as that of olive oil, and it contains specific physiologically active substances such as camellia saponin. Camellia oil is clear in color, fragrant in taste, durable in storage, and has extremely high nutritional value. It is a kind of pure natural high-grade oil unique to China. In recent years, Camellia oleifera...
