Embodiment 1

[0053] Embodiment 1 The plantation of Rhodiola angustifolia in the alpine sandy land in western Sichuan

[0054] The present invention will be described in further detail below by specific embodiment, and the control method of northwestern Sichuan alpine sandy land comprises the following steps:

[0055] 1. Confirmation of the restoration site The main restoration process: survey→fence construction→sand barrier construction→vegetation restoration; Grassland degradation grade classification shall be implemented according to GB19377-2003:

[0056] 1.1 Survey: Select moderately or severely degraded alpine sandy land, survey the basic information such as geographical location, grassland type, planting area, etc., and formulate an overall ecological restoration and vegetation restoration plan;

[0057] 1.2 Fence construction: Fence construction can be carried out before and after planting; the quality and erection of fences shall be implemented in accordance with the regulations of...

Embodiment 2

[0079] Embodiment 2 Plantation of Rhodiola grandiflora in alpine sandy land in western Sichuan

[0080] Embodiment 2 is different from Example 1 only in the selected species. In the present embodiment, Rhodiola grandiflora is used, and when rhizome ramet propagation seedlings are selected, when selecting Rhodiola grandiflora for use, the rhizome diameter ≥ 2cm, and the rhizome length ≥ 15cm. The rest of the steps are the same as in Example 1. Using the method in Example 2, Rhodiola rosea was successfully planted in the alpine region of Northwest Sichuan for the first time, and the survival rate of Rhodiola grandis can reach more than 70%.

Abstract

The invention relates to a method for restoring vegetation of high and cold sand land in Northwestern Sichuan, in particular to a method for sustainable management of the high and cold sand land in Northwestern Sichuan with rhodiola rosea and belongs to the technical field of agriculture. The method comprises the following steps that a, sand-protecting barriers are constructed; b, seeds are selected, wherein seedlings or root and stem division propagation seedlings of rhodiola rosea are selected, and rhodiola rosea is rhodiola crenulata or rhodiola kirilowii; c, planting is conducted, wherein the seedlings are transplanted to the high and cold sand land in Northwestern Sichuan in a hole planting mode in autumn; d, management is conducted, wherein fertilizer is applied and pest control is conducted; e, seeds are collected after rhodiola rosea grows for five years. According to the method for sustainable management of the high and cold sand land in Northwestern Sichuan with rhodiola rosea, rhodiola rosea is successively planted in the high and cold sand land in Northwestern Sichuan, and the survival rate of rhodiola kirilowii can reach over 90%; due to the fact that rhodiola rosea has certain economic value, if rhodiola rosea is successively grown in Northwestern Sichuan, the ecologic value and the economic value are both achieved, and the sustainability of management of the high and cold sand land in Northwestern Sichuan is achieved.

Description

technical field [0001] The invention relates to a method for restoring alpine sandy land in northwestern Sichuan in an alpine area or a similar area, in particular to a method for using Rhodiola rosea to sustainably control the alpine sandy land in western Sichuan, and belongs to the field of agricultural technology. Background technique [0002] Grassland degradation and desertification have become problems in China and the world at present, and Northwest Sichuan is no exception. [0003] Northwestern Sichuan is located on the southeastern edge of the Qinghai-Tibet Plateau. It is an important water conservation area for the Yangtze River and the Yellow River. The average altitude is above 3600m. The climate type belongs to the continental plateau cold temperate monsoon climate. , Long winter without summer, low heat; dry and rainy seasons are distinct, rainy and hot in the same season; sunshine is long, solar radiation is strong; disastrous weather is frequent. The annual ...
