Problems solved by technology

[0003] Traditional afforestation techniques have not solved or are difficult to solve the problem of large water consumption for afforestation in arid areas, making the cost of desert vegetation restoration and reconstruction high, not only wasting a lot of manpower, material and financial resources, but also difficult to receive the expected results. Effect
In addition, plants have shallow root systems and weak drought resistance at the seedling stage. If a large amount of water is supplied in the early stage and insufficient water is replenished in the later stage, the plants will die.

Embodiment 1

[0012] The size of the tree pit is 60 cm long, 60 cm wide, and 60 cm deep, with a sand covering thickness of 15 cm, a plant spacing of 1.5 meters, and a row spacing of 2 meters. Seedlings are selected from robust Haloxylon seedlings.

[0013] Application steps:

[0014] ①Selection of seedlings

[0015] The tree species planted are mainly native shrub species Haloxylon. The quality of seedlings is an important factor affecting the survival rate, so strong seedlings must be selected, and generally 2 to 3-year-old Haloxylon seedlings are used. Ensure a certain root length, ground diameter and above-ground height (about 50 cm), and the root system will not be damaged or split. Unqualified seedlings, diseased and insect seedlings, and disabled seedlings must not be used for afforestation.

[0016] ②Soil preparation

[0017] The afforestation site is selected in the open bare land, and the hole-like land preparation method is used to create seedlings and a natural settlement env...

Embodiment 2

[0021] When planting seedlings in a container, the container is first filled with water, and then a lateral root of the Haloxylon ungerminated seedling plant is inserted into the container. According to the height of the container and the plant, fill the pit with soil to a certain height, then put the container and the plant into the pit together, keep the container vertical, then fill the pit with soil 15 cm away from the ground (tree pit mouth), and finally fill the pit with soil. Cover the tree pit with sand until the pit is full, and smooth it out.

Abstract

The invention relates to novel technology and method for Haloxylon ammodendron forestation without irrigation in dry and desert areas. The method comprises steps of employing primitive shrub Haloxylon ammodendron as cultivation species, screening out plant pit size, sand-covering thickness by orthogonal experiment and storing water in container. The invention can be used in natural environment of rain precipitation below 100mm to 150mm, and vegetation restoration and reconstruction from vegetation degradation coming from natural and human interference.

Description

1. Technical field [0001] The invention relates to a desert vegetation restoration technology, in particular to a new technology and method for vegetation afforestation in arid desert areas without irrigation. 2. Background technology [0002] my country is one of the countries with the largest desert area and wide distribution in the world, and is most seriously harmed by desertification. In particular, Xinjiang is located in the hinterland of the Eurasian continent. Affected by the continental arid climate, most areas are in semi-arid, arid and extremely arid or alpine regions. Sparse, the ecological environment is very fragile. Although desert vegetation has fewer species and lower coverage, it constitutes the skeleton of the desert ecosystem and plays an important role in resisting natural disasters such as sandstorms and stabilizing the environment in arid areas. At the same time, with the growth of population, continuous economic development and excessive use of rene...
