Problems solved by technology

In the 1980s, my country once planted large-scale artificial pure forests for sassafras wood, but due to the immature afforestation model, the problem of "survival does not make forests, and mature forests do not grow into timber" is quite common

Embodiment

[0042] 1 Selection of afforestation sites:

[0043] Choose sunny or semi-sunny slopes, low mountains and hills below 800m above sea level; well-drained slightly acidic soil (pH4.5-6.5), try to avoid dry and barren or poorly drained waterlogged land; Law or secondary broad-leaved forest fires.

[0044] 2 Requirements for afforestation seedlings:

[0045] The seedling age of afforestation seedlings can be 1a or 2a; the main root system of sassafras seedlings is obvious, and the number of lateral roots is small. In order to ensure the survival rate of afforestation, container seedlings should be used as much as possible; when bare-root seedlings are used for afforestation, the root system must be kept intact before afforestation, and the root system must be kept intact before the afforestation. Use loess to make pulp; in order to avoid the death of seedlings caused by the evaporation of leaf water, the seedlings should be planted after the natural leaves of the seedlings fall in...

Abstract

The invention discloses a common sassafras bamboo timber forest forestation method which is characterized by including the steps: S1 forestation land selection, to be specific, selecting sunny slope or semi-sunny slope low mountains and hills with altitudes below 800m; S2 forestation nursery stock requirements, to be specific, allowing forestation nursery stock ages to be 1a and 2a; S3 mixed treespecies including evergreen broad-leaved tree species, evergreen coniferous tree species and deciduous broad leaved tree species in mixed forestation with common sassafras; S4 mixed modes including line mixing and mixing by single tress; S5 forestation density not higher than 833 plants per hectare, and performing cutting when standing forest ages reach 15 years to obtain maximum output; S6 tending management. Common sassafras bamboo timber forest forestation modes are standardized in terms of common sassafras bamboo timber forest forestation land selection, the nursery stock requirements, themixed tree species, the forestation density, tending management and the like, the most special social timber requirements are more effectively met, production efficiency is improved, and contradiction between supply and demand is relieved.

Description

technical field [0001] The invention relates to the technical field of afforestation, in particular to a method for afforestation of sassafras timber forests. Background technique [0002] Sassafras is mainly distributed in 13 provinces (autonomous regions) in subtropical regions of my country (23°-32°N, 102°-122°E), and is a traditional fast-growing broad-leaved timber species. Sassafras wood is excellent in material, moderate in density, not warped or cracked, easy to process, corrosion-resistant, and water-resistant. It can be used in shipbuilding, construction, handicraft carving and decorative panels. In the 1980s, my country had large-scale plantation of artificial pure forests for sassafras wood, but due to the immature afforestation model, the problem of "survival does not produce forests, and mature forests do not produce timber" is quite common. In recent years, with the improvement of people's living standards, in addition to the traditional use of wood, the char...
