Problems solved by technology

However, the single tree species structure and traditional management methods of eucalyptus plantations not only lead to soil fertility decline and carbon sequestration potential decline, but also cause a series of ecological problems such as soil erosion and carbon emissions, which threaten the healthy development and sustainable development of eucalyptus plantations. Operation poses huge risks

Embodiment 1

[0029] Step 1. Woodland preparation: chop up the harvesting residues in the woodland and keep them in the woodland, and then dig planting holes on the woodland after preparing the land in blocks. The row and plant spacing of the planting holes are both 2 meters. Apply 400g organic fertilizer in each plant hole.

[0030] Step 2, afforestation: select clonal eucalyptus and native tree species for afforestation, and plant holes in three adjacent rows as a group. In each group, eucalyptus is first planted in two adjacent rows near the periphery of the woodland, and the other row is planted with native tree species. The same groups are arranged in sequence, and the afforestation density is 90 trees / mu for eucalyptus and 30 trees / mu for mixed species.

[0031] Step 3, tending after afforestation: Within one year after afforestation, eucalyptus and native tree species are subjected to block tending three times, in the second year, native tree species are subjected to block tending tw...

Embodiment 2

[0037] Step 1. Woodland preparation: chop up the harvesting residues in the woodland and keep them in the woodland, and then dig planting holes on the woodland after preparing the land in blocks. The row and plant spacing of the planting holes are both 2 meters. Apply 600g of organic fertilizer in each plant hole.

[0038] Step 2, afforestation: select clonal eucalyptus and native tree species for afforestation, and plant holes in three adjacent rows as a group. In each group, eucalyptus is first planted in two adjacent rows near the periphery of the woodland, and the other row is planted with native tree species. The same groups are arranged sequentially, and the afforestation density is 100 trees / mu of eucalyptus and 40 trees / mu of mixed species.

[0039] Step 3, tending after afforestation: Within one year after afforestation, eucalyptus and native tree species are subjected to block tending three times, in the second year, native tree species are subjected to block tending t...

Embodiment 3

[0045] Forest land preparation: chop up the harvesting residues in the forest land and keep them in the forest land. Apply 500g of organic fertilizer to the hole.

[0046] Step 2, afforestation: select clonal eucalyptus and native tree species for afforestation, and plant holes in three adjacent rows as a group. In each group, eucalyptus is first planted in two adjacent rows near the periphery of the woodland, and the other row is planted with native tree species. The same groups are arranged in sequence, and the afforestation density is 95 trees / mu for eucalyptus and 35 trees / mu for mixed species.

[0047] Step 3, tending after afforestation: Within one year after afforestation, eucalyptus and native tree species are subjected to block tending three times, in the second year, native tree species are subjected to block tending twice, and in the third year, native tree species are block tended once.

[0048] Step 4. Fertilization: In the year of afforestation, biochar fertiliz...

Abstract

The invention discloses a management method for a eucalyptus tree man-made forest. The management method comprises the steps of: preparing a forest land: cutting up and retaining logging residues in the forest land, performing soil preparation, then digging plant holes, wherein during arrangement of the plant holes, every two narrow rows and one wide rows form a group, multiple same groups are arranged in sequence, and after the plant holes are dug, an organic fertilizer is applied to each plant hole; performing forestation: selecting clone eucalyptus trees and native tree species to perform forestation, planting the eucalyptus trees on the narrow rows, and planting the native tree species on the wide rows; performing tending after forestation; performing fertilization: and performing cutting and constructing a multiple layered forest. According to the management method disclosed by the invention, by virtue of the means of adjusting the structure of the tree species, improving fertilizing and tending manners and updating a cutting mode, the productivity and carbon stock of the eucalyptus tree man-made forest are significantly improved, the capabilities of emission reduction and sink increment of the eucalyptus tree man-made forest are increased, the economic benefit and ecological benefit of the eucalyptus tree man-made forest are improved, the forest land is fully utilized, water and soil losses and land capability decline are effectively prevented, and sustainable management of the eucalyptus tree man-made forest is realized.

Description

technical field [0001] The present invention relates to the field of forestry. More specifically, the present invention relates to a method for managing eucalyptus plantations. Background technique [0002] Artificial forest is a forest cultivated by artificial sowing, planting or cutting and other methods and technical measures. According to the different breeding and cultivation methods, it is generally divided into seeding forest, seedling forest and cuttings forest. Plantation forests are concentrated in places with convenient transportation according to certain purpose requirements and forest species that people need, and intensive management measures such as breeding of good species, suitable trees for the right place, moderate density, and tending management are generally adopted for establishment and cultivation. Compared with natural forests, artificial forests have the characteristics of fast growth, high growth volume, convenient development and early benefit, t...
