Embodiment 1

[0011] A kind of method that utilizes tiger thorn to carry out rocky desertification ecological vegetation restoration of the present invention, comprises steps as follows:

[0012] (1) Peel off the shell of the tiger thorn seeds before sowing, soak in 900mg / L-1000mg / L potassium permanganate solution for 10 minutes, remove the suspended unfulfilled seeds, and then store them in sand. The ratio of 1:2 is fully mixed evenly, and the uppermost end is covered with 3cm of pure sand. After being fully wetted with water, it is placed in a dry, dry and ventilated place. After 20 days of sand storage, check the moisture of the seeds to remove mold or excessive water loss, etc. Unhealthy seeds.

[0013] (2) In the field, select the stone surface or stone ditch on the rocky desertification hillside where the succession state is the shrub-grass stage and the shrubs are relatively rare, and use pits to prepare the land. 2m, interspersed with the original bushes (try to protect the origina...

Embodiment 2

[0015] A kind of method that utilizes tiger thorn to carry out rocky desertification ecological vegetation restoration of the present invention, comprises steps as follows:

[0016] (1) Peel off the shell of the tiger thorn seeds before sowing, soak in 900mg / L potassium permanganate solution for 15 minutes, remove the suspended unfulfilled seeds, and then store them in sand. When storing in sand, the ratio of seeds to sand is 1:2 Stir well and evenly, cover the top end with 3cm of pure sand, and put it in a dry, ventilated place after being fully wetted with water. After 18 days of sand storage, check the water condition of the seeds, and remove unhealthy seeds such as moldy or excessive water loss.

[0017] (2) In the field, select the stone surface or stone ditch on the rocky desertification hillside where the succession state is the shrub-grass stage and the shrubs are relatively rare, and use pits to prepare the land. 2m, interspersed with the original bushes (try to prote...

Embodiment 3

[0019] A kind of method that utilizes tiger thorn to carry out rocky desertification ecological vegetation restoration of the present invention, comprises steps as follows:

[0020] (1) Before sowing, peel off the shell of tiger thorn seeds, soak in 1000mg / L potassium permanganate solution for 12 minutes, remove the suspended unfulfilled seeds, and then store them in sand. The ratio of seeds and sand is 1:2 when storing in sand. Stir well and evenly, cover the top end with 4cm of pure sand, and put it in a dry, ventilated place after being fully wetted with water. After 19 days of sand storage, check the water condition of the seeds, and remove unhealthy seeds such as moldy or excessive water loss.

[0021] (2) In the field, select the stone surface or stone ditch on the rocky desertification hillside where the succession state is the shrub-grass stage and the shrubs are relatively rare, and use pits to prepare the land. 2m, interspersed with the original bushes (try to protec...

Abstract

The invention discloses a method for restoring stony-desertification ecological vegetation by using damnacanthus indicus. The method comprises the steps: shelling seeds of damnacanthus indicus beforesowing, soaking the shelled seeds in a potassium permanganate solution, removing suspending non-full seeds, and then, carrying out sand storing treatment; and selecting stone surfaces and stone drainsof a stony-desertification hillside, of which a succession state is a shrub-grass stage and shrubs are relatively scarce, in the open air, performing pit-shaped land preparation, protecting originalshrub-grass vegetation during land preparation, carrying out dibble seeding at the beginning of March while carrying out land preparation, sowing 1 to 2 seed grains to each pit, covering pits with overturned original soil after sowing, sufficiently watering after sowing until the seeds germinate, then, carrying out uninterrupted tending management, and carrying out pruning. According to the method, the treatment progress is fast, the cycle is short, the landscape effect can be improved, and the labor intensity of manual curing is alleviated.

Description

technical field [0001] The invention belongs to the field of ecological management of rocky desertification, and specifically relates to a method for restoring rocky desertification ecology by using tiger thorns. Background technique [0002] The formation of rocky desertification is mainly related to two factors: artificial and unreasonable cultivation and very slow bedrock soil formation. As a result, water and soil loss, vegetation degradation, and large-scale exposed rocks are caused, showing a phenomenon similar to "rocky desertification" or "rocky desertification". Ecological landscape of degraded land. [0003] The rocky desertification mountainous area is a typical ecological crisis area, with barren soil and poor living conditions for residents. In order to solve the problems of rocky desertification ecological restoration, low vegetation coverage, and barren soil, the main ecological management methods are closing hills for afforestation, afforestation on barren...
