Problems solved by technology

The establishment of the shelterbelt system plays a vital role in the sustainable development of the oasis society and economy. However, the model of the shelterbelt system on the southern edge of the Junggar Basin has been relatively single for many years. 2-3 technical measures have caused the protection forest system to be unsound, and under the influence of harsh natural factors, its ecological protection function has been seriously weakened

Embodiment 1

[0029] It was implemented at the front of the 25th Company of the 150th Regiment of the Eighth Division of the Xinjiang Production and Construction Corps (N45°08′5.9″, E86°00′38.8″). The demonstration area is located at the southern edge of the Junggar Basin, and has typical mid-temperate continental arid and semi-desert climate characteristics. Proceed as follows:

[0030] Selection of construction site for oasis shelterbelt system in arid desert area: choose an area with sand sources on the edge of the oasis and rainfall > 100mm;

[0031] The first zone of oasis shelterbelt (general enclosure area): fence enclosure protection measures are adopted for the natural Haloxylon forest, with a width of 5km;

[0032] Oasis Shelterbelt Zone 2 (Key Enclosure Area): Width 6.5km, on the basis of fence protection, and in areas with vegetation coverage < 0.3, artificial intervention measures are taken to assist artificial seeding. The selected plant species are Haloxylon, Sow 2.0-4.0 kg...

Embodiment 2

[0038] In the junction of the desert and the oasis in the northern part of Midong District, the 102nd Regiment 17 Company of Midong District, Urumqi City (N44°21′56.6″, E87°45′18.2″). The demonstration area is located at the southern edge of the Junggar Basin, and has typical mid-temperate continental arid climate characteristics, with hot summers, cold winters, low precipitation, large evaporation, sufficient sunlight, abundant heat, and large daily and annual temperature ranges. The surface is exposed to rich sand, and the specific steps are as follows:

[0039] Selection of construction site for oasis shelterbelt system in arid desert area: choose an area with sand sources on the edge of the oasis and rainfall > 100mm;

[0040] The first zone of oasis shelterbelt (general enclosure area): fence enclosure protection measures are adopted for the natural Haloxylon forest, with a width of 5.5km;

[0041] Oasis Shelterbelt Zone 2 (Key Enclosure Area): Width 7.0km. On the basis ...

Abstract

The invention discloses a method for planting oasis protection forest in an arid desert region. Planting of first to sixth zones of the protection forest is performed in a region, which has sand sources at oasis edges of the arid desert region and has rainfall greater than 100mm. The method disclosed by the invention has the beneficial effects that 1, different forest categories are arranged from the periphery to the interior of the oasis, so that the whole oasis is uniform in plant distribution and reasonable in layout; 2, not only can desertization at the periphery of the oasis be prevented and controlled, but also wind-sand disaster in the oasis can be prevented and controlled, and the agroecological environment is improved; 3, according to the method, regional environment conditions are utilized, so that the method is easy to implement, rapid in effect taking and good in effect, and has relatively high practicability and operatability; and 4, after the method is implemented, the effect is obvious, through applying the technology to a sand-prevention and sand-resistant region, 85.7%-96% of sand particles of wind-drift sand sediment runoff can be settled, the wind speed is averagely reduced by 36.8% within a 20-times tree height range of a backbone protection forest zone region, and due to the existence of agroforestry, the yield increase rate of wheat is not less than 11%, and the yield increase rate of corn is not less than 10.7%.

Description

technical field [0001] The invention relates to the technical field of desert planting, in particular to a planting method of an oasis shelterbelt in an arid desert area. Background technique [0002] Agriculture in arid desert areas "water conservancy is the lifeline, forestry is the guarantee", both are indispensable. As an important part of farmland capital construction, farmland shelterbelts are the main body and foundation of oasis ecological environment construction in arid areas. As far as the Junggar Basin is concerned, high-efficiency farmland shelterbelts should have the characteristics of good protection benefits, high economic value, strong stress resistance, and water saving. After years of practice, the pattern of shelterbelt system construction from desert to oasis is as follows: general enclosure → key enclosure → non-irrigated afforestation area → sand prevention and sand blocking belt → basic shelterbelt → farmland shelterbelt network, namely: Zone 3-2 Be...
