Problems solved by technology

[0004] The commonly used tree species for direct seeding afforestation are Caragana and Artemisia annua, which have low survival rate and slow growth, but because of their low cost, they are often used in semi-fixed sandy land and inter-dune land; seedling afforestation technology is commonly used in mobile sand dunes in various sandy areas Afforestation technology, but its seedling cycle is long and the cost of purchasing seedlings is high, so it is not suitable for long-term promotion and application; due to the severe cold climate conditions and lack of soil moisture in the alpine sandy area, the survival rate of seedlings is low

Embodiment Construction

[0021] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0022] figure 1 It is a schematic diagram of the planting of willow willow in mobile sand dunes in a specific embodiment of the present invention. Such as figure 1 As shown, in the mobile sand dunes, the planting of willow willow is carried out. At first, the seedlings are cut from the thriving willow tree in spring. The diameter of the seedlings is 2 to 3 cm, and the height is 100 cm. After soaking the seedlings After more than 20 days, the tree seeds are planted on high poles and deep in the mobile sand dunes. The depth of the planting pit is 80 cm, the diameter is 30 cm, and the planting density is generally 1.5 meters × 1.5 meters.

[0023] Wheatgrass sand barriers play an extremely important role in sand control. They can fix quicksand, reduce the wind speed near the surface, and prevent vege...

Abstract

The invention discloses a mobile dun salix cheilophila planting method, which comprises the following steps that: sapling is fetched from salix cheilophila seed trees in spring, the sapling is soaked for more than 20 days and then is transported to a planting region, and the sapling is long stalked and deep planted on mobile dunes. By adopting the technical scheme provided by the invention, the cost is low, the forestation method is simple, the survival rate is high, and the formation speed is fast.

Description

technical field [0001] The invention relates to the technical field of building windproof and sand-fixing forests in alpine regions, in particular to a method for planting willow willows in mobile sand dunes. Background technique [0002] The prevention and control of desertification in alpine regions is an urgent and arduous task. Since the 1950s, the desertification phenomenon of the Qinghai Plateau has been paid attention to, and a series of desertification prevention and control work has been carried out in the Gonghe Basin since the 1960s. With the continuous deepening of sand control work, some effective sand control measures have begun to be formed and gradually popularized and applied in the Qinghai Plateau. [0003] Commonly used afforestation techniques for desertification control in alpine regions include direct seeding afforestation, seedling afforestation and stem-inserting afforestation on sand dunes, and deep afforestation of poplars and willows in inter-dune ...
