Problems solved by technology

However, the existing mixed-crossing modes are all traditional inter-row mixed, strip-shaped mixed-crossed, and block-shaped mixed-crossed. The use of traditional models has brought many disadvantages, such as suppressing the growth of main tree species, which cannot reduce plant diseases and insect pests, increase economic benefits, and improve stand ecology and environmental protection. The function of stress resistance, the scientificity, rationality and operability of mixed forests are not strong, and the effect and function of artificial mixed forests close to nature cannot be achieved.

Embodiment 1

[0031] Implementation site: Guangxi State-owned Gaofeng Forest Farm

[0032] The test forest was afforested in March 2009, and the afforestation adopted excavated ridges (blocks) for site preparation. The size of the site preparation was 40×40×30cm, the spacing between plants and rows was 1.5m×3m, and the initial planting density was 2222 plants / hm 2 The base fertilizer is a compound fertilizer with a content of 25%. Masson pine seedlings adopt semi-annual nutritional cup seedlings from Guangxi Academy of Forestry, with an average seedling height of 25cm, reaching the national first-class seedling standard. 30cm high.

[0033] The experiment was a randomized block design, and the mixed crossing ratios of masson pine and red cone were designed as shown in Table 1.

[0038] Firstly, according to the mixed experiment of masson pine and red cone, the effects of pure forest and mixe...

Embodiment 2

[0040] Implementation location: Longlin Farm, Hengxian County, Guangxi

[0041] The species that are suitable for local mixed with masson pine include red cone, lotus, oak, sweetgum, camphor, lattice, rosewood, nan and zhennan.

[0042] Determine several models of mixed forests, including: masson pine mixed with Gemu, Quercus japonica, and Dalbergia balsamicus; Several kinds of Dalbergia mixed. Determine the planting density as the planting density is 2000 plants / hm 2 . Set the mixing ratio of masson pine with Quercus japonica, Gemu, and Dalbergia japonica to 60:15:10:15, and the ratio of masson pine to camphor, Gemu, and Nannan to 70:10:10:10. The mixing ratio with red cone, apical fruit and Dalbergia japonica is 65:15:10:10.

[0043] The masson pine seedlings used should meet the national first-class seedling standards, and the mixed tree seedlings are annual seedlings. The size of the planting hole for planting is 40cm×40cm×30cm, and 0.5kg of calcium magnesium phosphat...

Abstract

The invention discloses a method for constructing a pinus massoniana close-to-nature mixed frost of a same age. The method comprises the following steps: randomly arranging and planting pinus massoniana, fast-growing broad leaf tree species and valuable broad-leaved tree species according to a ratio of (60-70):(20-25):(10-15). By adopting the method, conventional mixing modes are changed, biological characteristics of tree species are utilized, a mutual promotion function can be achieved, trees can grow in an approximate natural manner, relatively long economic and ecological benefits can be produced, relatively good practicability and operability can be achieved, and an effective way for promoting management of the pinus massoniana close-to-nature mixed frost can be provided. Therefore, the method is very wide in application prospect and applicable to large-scale pinus massoniana mixed forestation.

Description

technical field [0001] The invention belongs to the field of tree cultivation, in particular to a method for building a masson pine near-natural mixed forest at the same age. Background technique [0002] Masson pine is an important timber tree species in my country. Because of its fast growth, high rosin yield and wide application, it plays an important role in my country, especially in the southern forestry economy and ecology. my country is the origin of Pinus massoniana. There used to be a large amount of natural forest area, and the ecological effects and functions are very obvious. However, driven by economic interests, natural forests have been severely damaged and replaced by planted pure forests, while planted pure forests have continued to expand in disease and insect pests, the probability of fires has continued to increase, soil erosion, soil fertility decline, environmental degradation and other problems Constantly highlighted. [0003] With the development of...
