Embodiment 1

[0035] Embodiment 1: the mixed afforestation of pines and Chinese fir with three strains of cluster planting

[0036] 1. Overview

[0037] On the basalt platform of Dongzhai Village, Dashiju Town, Xinchang County, where the fertility is poor, 0.2h㎡ of mixed pine and fir forests are implemented (hm means "hundred meters", h㎡ means "square hundred meters", 1 square hundred meters = 100 *100 square meters = 10,000 square meters, that is, 1 hectare).

[0038] 2. Large block land preparation

[0039] In the 2-year-old masson pine young forest, carry out large block land preparation. The block size is 1㎡, and the block spacing is 3.33m. 60 large plots per 667㎡. When preparing the ground, dig out the pine trees in the blocks and keep the pine trees in the blocks.

[0040] 3. Plant fir trees

[0041] In February, 3 Chinese fir seedlings were planted in each block, arranged in an equilateral triangle. The distance between plants is 50cm. Plant 180 fir seedlings per 667 square...

Embodiment 2

[0044] Embodiment 2: the group planting pine and fir mixed afforestation of the combination of two strains of clumps

[0045] 1. Overview

[0046] In the Huangshan pine young forest (three-year-old) in Luokeng Mountain, Xinchang County, Zhejiang Province, at an altitude of 900m, Chinese fir seedlings were planted mixed with an area of ​​0.6 h㎡.

[0047] 2. Strip land preparation

[0048] In Huangshan pine juvenile forest land, band-shaped land preparation was carried out along the horizontal direction. The bandwidth is 1m, and the distance between the belts is 4m. In the scope of land preparation within the belt, the pine trees shall be dug out, and the pine trees in the belt shall be preserved.

[0049] 3. Chinese fir planting

[0050] In February, Chinese fir seedlings were planted in the zone. There are two plants in one clump, and the distance between the plants in the clump is 50cm, in a straight shape. The indirect distance of the inner plexus is 2 m. About 13...

Abstract

The invention discloses a pine-fir mixed forestation method using group planting, which belongs to mixed forest planting methods and includes: subjecting fir seedlings to bunch planting in young stands of biennial masson pine; or subjecting fir trees to bunch-belt mixed planting in young stands of triennial Huangshan pine in mountain lands more than 800m in elevation; and obtaining a pine-fir mixed forest. By the pine-fir mixed forestation method using group planting, the pine trees are given to pull play to protect and promote the fir trees, the fir trees can be planted well and grown normally in high-elevation places basalt platform places with poor soil. Stock volume per 667m2 is more than doubled, and economic benefit and ecological benefit are evident.

Description

technical field [0001] The invention relates to a mixed afforestation method among different tree species, in particular to a group planted pine and fir mixed afforestation method, which can make the firs plant successfully and grow normally in some places that are not suitable for growth. Background technique [0002] Mixed afforestation is to plant two or more tree species together according to certain specifications and proportions. Among them, each kind of trees accounts for no less than 10% of the forest, and the forest stand formed by it is called mixed forest. [0003] Mixed afforestation and the mixed forests it constitutes have many advantages. The economic benefit and ecological benefit are both high; it can prevent and reduce pests and diseases; some tree species can be successfully planted in some places that are not suitable for growth, etc. [0004] The mixed afforestation methods include inter-row intermixing, inter-row intermixing, ribbon intermixing and bl...
