Embodiment 1

[0028] The afforestation method of interplanting nanmu under the masson pine canopy comprises the following steps:

[0029] 1) Thinning: select the 15-year-old Pinus massoniana stand with good growth and better site conditions for thinning, and keep the canopy density of 0.4 after thinning;

[0030] 2) Digging holes: Dig holes under the canopy of Masson pine after thinning. The size of the holes is 50cm×50cm wide, 30cm×30cm wide at the bottom, 30cm deep, and the density is 1200 holes / hm 2 ;

[0031] 3) afforestation: select the rainy day in January to implant the annual Phoebe seedlings into the caves dug in step 2), and carry out afforestation by planting seedlings;

[0032] 4) Tending: From 1 to 3 years after afforestation, block weeding is used to tend Phoebe, twice a year, in May and September respectively; from 4 to 5 years after afforestation, Phoebe is tended by weeding , once a year, in July.

[0033] After observation, it can be found that after interplanting nanmu...

Embodiment 2

[0037] The afforestation method of interplanting nanmu under the masson pine canopy comprises the following steps:

[0038] 1) Thinning: select the 18-year-old Pinus massoniana stand with good growth and better site conditions for thinning, and keep the canopy density of 0.5 after thinning;

[0039] 2) Dig holes: Dig holes under the canopy of Masson pine after thinning. The size of the holes is 60cm×60cm wide, 35cm×35cm wide at the bottom, 35cm deep, and the density is 1350 holes / hm 2 ;

[0040] 3) afforestation: select the rainy day in February to implant the annual Phoebe seedlings into the cave dug in step 2), and carry out afforestation by planting seedlings;

[0041] 4) Tending: From 1 to 3 years after afforestation, use block weeding to tend Phoebe, twice a year, in June and October respectively; from 4 to 5 years after afforestation, use weeding to tend Phoebe , once a year, in August.

[0042] After observation, it can be found that after interplanting nanmu under t...

Embodiment 3

[0046] The afforestation method of interplanting nanmu under the masson pine canopy comprises the following steps:

[0047] 1) Thinning: select the 20-year-old Pinus massoniana stand with good growth site conditions and carry out thinning, and keep the stand canopy density of 0.6 after thinning;

[0048] 2) Digging holes: Dig holes under the canopy of Masson pine after thinning. The size of the holes is 55cm×55cm wide, 35cm×40cm wide at the bottom, 40cm deep, and the density is 1500 holes / hm 2 ;

[0049] 3) afforestation: select the rainy day in January to implant the annual Phoebe seedlings into the caves dug in step 2), and carry out afforestation by planting seedlings;

[0050] 4) Tending: From 1 to 3 years after afforestation, block weeding is used to tend Phoebe, twice a year, in June and September respectively; from 4 to 5 years after afforestation, Phoebe is tended by weeding , once a year, in August.

[0051] After observation, it can be found that after interplanti...

Abstract

The invention provides a forestation method of interplanting a phoebe bournei yang under masson pine crown canopy. The method comprises the steps of conducting intermediate cutting on a masson pine forest stand to lower the canopy density of the original masson pine forest stand; digging holes under a masson pine forest crown canopy which is subjected to intermediate cutting; planting phoebe bournei yang saplings in the dug holes to conduct forestation; nurturing the phoebe bournei yang saplings after forestation. According to the technical scheme, by interplanting the phoebe bournei yang under the masson pine forest crown canopy, the ecological functions of an original masson pine forest can be maintained, the biological characteristics of the masson pine and phoebe bournei yang tree varieties can be made full use of, the pure masson pine forest is cultivated into an uneven-aged multi-layer mixed conifer-broadleaf forest, the forest stand quality is improved, the economic benefit is increased, the ecological function of the forest stand is promoted, and a new method and a new path are provided for the development of the rare tree variety of the phoebe bournei yang.

Description

technical field [0001] The invention relates to the technical field of forestry forest resource cultivation, in particular to an afforestation method for interplanting nanmu under a masson pine canopy. Background technique [0002] Masson pine (scientific name: Pinus massoniana Lamb.) is a Pinaceae, Pinus tree, up to 45 meters high, 1.5 meters diameter at breast height; bark reddish-brown, branches flat or oblique, crown wide tower or umbrella, branches grow every year One round (two rounds in Guangdong), winter buds ovoid-cylindrical or cylindrical, needles, soft, slightly twisted, with stomatal lines on both sides, and fine serrations on the edges; leaf sheaths persistent. Male cones are light reddish brown, cylindrical, clustered in the bract axils of the lower part of new branches, spike-shaped, female cones are clustered near the top of new branches, lavender, long oval seeds, flowering in April-May, cones second Mature in October-December. Masson pine is widely distr...
