Problems solved by technology

[0005] Although the shrub community is less effective in bringing into play the function of water conservation, it is a stage that cannot be crossed in the regional ecological restoration process. Therefore, it is the present invention to rationally use the regional shrub community and accelerate the succession of the secondary shrub community to the arbor top community. the purpose of

Embodiment 1

[0058] See attached Figure 10-12 According to the implementation examples of the present invention, optimal measures are taken according to the shrub community characteristics and climate characteristics on the east slope of the Taihang Mountains to realize the improvement of the water conservation function in this area.

[0059] (1) In order to achieve the function of water conservation in the rainy season and reduce the consumption of soil moisture after the rainy season, the vegetation in the Vitex shrub area was harvested in late September. The function of shrub vegetation to maintain water and soil during the rainy season can also reduce the consumption of soil moisture after the rainy season. In addition, the preservation of the root system is conducive to the germination and growth of vegetation, and will continue to play the water and soil conservation function of Vitex shrubs in the next rainy season.

Embodiment 2

[0072] This embodiment relates to a device that utilizes Vitex shrubs to improve water conservation capacity in rocky mountainous areas, such as Figure 1-3 As shown, it includes a frame body 1, a guide rail 2, an angle adjustment mechanism and an excavation and backfill mechanism. Wherein, the frame body 1 is fixedly installed on the car body, and extends out of the car body, and one end of the guide rail 2 is pivotally connected with the protruding end of the frame body 1, and the angle adjustment mechanism is installed between the frame body 1 and the guide rail 2. The different slopes of the surface adjust the angle between the guide rail 2 and the frame body 1, so that the guide rail 2 is in a state of vertical extension, and one end of the excavation and backfill mechanism is slidably connected to the guide rail 2, and the excavation and backfill mechanism extends to the ground for ground excavation and Vitex crushing. The present invention moves with the vehicle body, a...

Abstract

The invention discloses a method for accelerating succession of a secondary shrub community in an earth-rock mountainous area to a top-level arbor community by using a vitex negundo shrub, which retains or introduces the vitex negundo shrub community on one hand, exerts the natural effect of the vitex negundo shrub community in the ecological restoration process of a region on the other hand and aims at the disadvantages of the vitex negundo shrub community in water conservation. Systematic manual intervention is carried out on the vitex negundo bush to improve the physical and chemical properties of soil, improve the conservation capacity of water sources and accelerate the ecological restoration process of the earth-rock mountainous area.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a method for improving water conservation capacity in earth-rock mountainous areas by using Vitex shrubs. Background technique [0002] The shrub ecosystem in northern my country is rich in resources, with a total area of ​​5365hm 2. , is an important terrestrial ecosystem. In the northern low mountain and hilly area, the climatic conditions are mainly semi-arid and semi-humid climate, and the annual average rainfall is about 500-600mm. Although it meets the conditions for forest formation, it is severely disturbed by human activities and limited by climatic conditions. The soil is thin, and the soil is poor and water-holding and water-holding capacity is weak, which seriously restricts the community succession process in this area. [0003] See attached Figure 9 , the study on the soil water use efficiency of typical vegetation in Taihang Mountains showed that ...
