Problems solved by technology

[0004] The present invention provides a method of direct seeding afforestation in the sandy area of ​​​​the sandy area of ​​arid and extremely arid areas, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem. Currently, the cost of Haloxylon afforestation in arid and extremely arid sandy areas is high, the survival rate and preservation rate are low, and the afforestation time is short, and the afforestation seedlings are difficult to raise, transport and plant

Embodiment 1

[0015] Embodiment 1, the method for afforestation directly in the sandy region Haloxylon growing season in this arid, extremely arid region, is carried out as follows: the first step, the afforestation land is determined, and the sandy land that can implement drip irrigation is selected as afforestation in arid, extremely arid regions The second step is to lay drip irrigation pipes on the afforestation ground. The distance between two adjacent drip irrigation pipes is 2 meters to 3 meters, and the distance between two adjacent drippers on the drip irrigation pipes is 1 meter to 1.5 meters. For irrigation, drip irrigation is carried out on the afforestation land in a conventional way, and drip irrigation is carried out for 2 hours before sowing; the fourth step is sowing, sow seeds on the afforestation land immediately after drip irrigation, and plant 10 to 12 shuttles in the wet area after drip irrigation of each dripper Shuttle seeds; the fifth step, manage the shuttle seeds...

Abstract

The invention relates to the field of afforestation technologies, in particular to a direct-sowing afforestation method for desert haloxylon of arid and extremely arid areas in the growing season. The direct-sowing afforestation method for the desert haloxylon of the arid and extremely arid areas in the growing season comprises the first step of determining afforestation land, the second step of laying drip irrigation pipes on the afforestation land, the third step of performing irrigation before sowing, the fourth step of sowing, the fifth step of performing current-year management after direct-sowing of haloxylon seeds, and the sixth step of performing next-year management after sowing. Compared with an existing afforestation method, according to the direct-sowing afforestation method for the desert haloxylon of the arid and extremely arid areas in the growing season, the survival rate and the retention rate are substantially increased, cost is greatly reduced, afforestation time is prolonged, and the afforestation method is not affected by weather.

Description

technical field [0001] The invention relates to the technical field of afforestation, and relates to a method for afforestation by direct seeding in the growing season of the Haloxylon in sandy areas in arid and extremely arid regions. Background technique [0002] Haloxylon is distributed in arid and extremely arid areas in Northwest my country. It has excellent characteristics such as drought resistance, cold resistance, high temperature resistance, sand burial resistance, salt and alkali resistance, and strong adaptability. It is one of the most important tree species for afforestation in arid and extremely arid sandy areas. , in addition to windbreak and sand fixation, Haloxylon is also a host plant for inoculation of Cistanche deserticola in the sand industry. It is widely used in forestry and ecological construction, and more than 3 million mu of Haloxylon forests need to be built every year. At present, with the development of social economy, ecological (forestry) cons...
