Problems solved by technology

For the afforestation of shrub barren hills, the traditional afforestation method of "refining mountains" not only easily causes forest fires, but also causes soil erosion, biodiversity decline, and CO 2 The discharge is serious, and the target saplings and native tree species in the shrub barren hills are burned, which is a waste for the regeneration of mixed forests
In addition, the roots of shrubs are thick and difficult to dig out, and new shoots sprout from unburned tree stumps, which not only endangers the growth of saplings, but also brings inconvenience to afforestation operations.

Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with specific implementation methods.

[0010] A kind of cultivation method of bush barren hills afforestation technology, comprises following technological process:

[0011] Mechanical cutting and irrigation-→filling piles and applying pesticides-→digging afforestation belts-→mechanical digging holes-→applying hole bottom fertilizer-→returning soil to make piers-→afforestation-→sapling management. in:

[0012] 1. Mechanical brush cutting: use Xinghua brand BG brush mower to cut shrubs and weeds. The machine is composed of a two-stroke or four-stroke gasoline engine, a flexible shaft assembly, an operating rod, and a saw blade. It can cut not only shrubs but also small trees with stems less than 20 cm. It is better to use a saw blade with ≥40 teeth for cutting shrubs and small trees. When cutting shrubs, proceed from bottom to top and from right to left on the barren hills of shrubs, and ...

Abstract

The invention belongs to the technical field of forestry and particularly relates to a cultivation method by afforestation technique for barren hills with shrub. The cultivation method includes the steps of mechanical shrub cutting, drug application to shrub stubbles, mechanical digging, application of hole-bottom fertilizer, moulding of returning topsoil, afforesting, and management of young growth. The cultivation method has the advantages that traditional 'controlled-burning' afforestation is replaced, 'burning'-free ecological afforestation with minimum tillage or no tillage is achieved, biodiversity of forest lands is protected, original ecology of the forest lands is protected, target tree species in the barren hills with shrub are reserved, and afforesting cost is saved for construction of mixed forests. Process steps of afforestation of the barren hills with shrub are repeatedly tested and summarized, and accordingly the cultivation method is highly scientific, high in practicality and detailed in operational guidance and is effective for sustainable development of forestry.

Description

technical field [0001] The invention belongs to the technical field of forestry, and specifically relates to a farming method related to shrub barren hill afforestation technology. Background technique [0002] Shrubs refer to plants with ground stems > 1 cm < 6 cm, height within 2.6 meters, and plants with xylem and phloem. There are often purpose saplings, native tree species and non-purpose saplings in shrub barren hills. For the afforestation of shrub barren hills, the traditional afforestation method of "refining mountains" not only easily causes forest fires, but also causes soil erosion, biodiversity decline, and CO 2 The discharge is serious, and the purpose saplings and native tree species in the shrub barren hills are all burned, which is a waste for the regeneration of mixed forests. In addition, the roots of shrubs are thick and difficult to dig out, and new shoots sprout from unburned stumps not only endanger the growth of saplings, but also bring inconv...
