Problems solved by technology

Bare-root seedling afforestation technology has a long seedling cycle, high cost of purchasing seedlings, high difficulty in planting, and low preservation rate, so it is not suitable for long-term promotion and use in alpine sandy areas
Mechanical sand-fixation measures use materials such as wheat straw, clay, straw ropes, gravels, nylon nets, and PVC woven bags as sand barriers, which can achieve the purpose of fixing mobile sand dunes in a short period of time. Good sand control effect

Embodiment 1

[0037] Application of the alpine sandy area vegetation recovery comprehensive management method of the present invention in Qinghai alpine sandy area mobile sand dunes in the steps of sand fixation are as follows:

[0038] 1. Material preparation: Seeds for live-seeding afforestation are Artemisia annua and Caragana seeds above grade II (DB63 / T539-2005), and the branches of willow for deep planting are cut from the mother tree in spring; materials for sand barriers include wheat straw and clay , nylon mesh, pebbles and PVC woven bags; deep planting equipment includes high-pressure water guns, water tanks, and transport machinery.

[0039] The seeds of Artemisia annua and Caragana for direct seeding are collected on-site in the alpine sandy area of ​​Qinghai. The quality of the seeds is required to meet the standards of Qinghai Provincial Standard II or above (DB63 / T539-2005), and the purity of the seeds is required to be no less than 90%. Germination The rate is not less than ...

Embodiment 2

[0055] The difference between this embodiment and Example 1 is that the method for sand-fixing in mobile sand dunes in the alpine sand area of ​​Qinghai is applied to the comprehensive management method for vegetation restoration in the alpine sand area of ​​the present invention:

[0056] 1. The material preparation step is Artemisia annua seeds;

[0057] 2. Nylon net sand barrier is selected in the sand barrier setting step;

[0058] 3. In the step of deep planting and afforestation, soak 2 / 3 of the cuttings of willow willow in clean water to absorb enough water for about 30 to 40 days.

[0059] All the other steps are the same as in Example 1.

Embodiment 3

[0061] The difference between this embodiment and Example 1 is that the method for sand-fixing in mobile sand dunes in the alpine sand area of ​​Qinghai is applied to the comprehensive management method for vegetation restoration in the alpine sand area of ​​the present invention:

[0062] 1. Caragana seeds are selected in the material preparation step;

[0063] 2. The sand barrier setting steps are PVC woven bag sand barriers;

[0064] 3. The step of deep planting and afforestation adopts manual digging of deep caves.

[0065] All the other steps are the same as in Example 1.

Abstract

The invention provides an arctic-alpine sandy area vegetation recovery comprehensive treatment method. After materials are prepared, the method includes, performing one in 1 to 4 steps; 1, performing deep planting afforestation; 2, arranging a sand barrier, and performing deep planting afforestation in the arranged sand barrier; 3, arranging a sand barrier, and performing direct seeding afforestation in the arranged sand barrier; 4, after arranging a sand barrier, performing deep planting afforestation and direct seeding afforestation in the arranged sand barrier. Material preparation means preparing afforesting seedlings and sand barrier materials; direct seeding afforestation includes in the arranged sand barrier, after rain, timely seeding Artemisia and / or Caragana as soon as possible in a manners of spot seeding or broadcast seeding and single seeding or mixed seeding; deep planting afforestation includes soaking Salix cheilophila branches, and digging one deep hole and planting one Salix cheilophila branch. In arctic-alpine sandy area, mechanical sand fixation and biological sand fixation are combined, a vegetation recovery comprehensive technology combines cutting and direct seeding afforestation under the non-irrigation condition, and the method is one of the most effective manners of optimizing sandy area ecological environment.

Description

technical field [0001] The invention relates to a comprehensive management method for vegetation recovery in alpine sandy areas. Background technique [0002] The alpine sandy area of ​​Qinghai is one of the areas seriously endangered by desertification in my country. In 1958, the Qinghai Provincial Sand Control Experimental Station carried out a series of desertification prevention and control work in the Shazhuyu area of ​​Gonghe County, Qinghai Province, summed up some effective comprehensive techniques for vegetation restoration in alpine sandy areas, and promoted successful governance models and methods in Qinghai Province. Experience has produced a positive driving and radiating effect. [0003] In the alpine sandy area, there is little precipitation and strong wind and sand. In such a harsh environment, the survival rate and forestation rate of afforestation in sand dunes (land) are technically difficult. In the past, bare-root seedlings or mechanical sand fixation ...
