Problems solved by technology

[0003] At present, the main problems faced by Populus euphratica forests in the Tarim River Basin are as follows: First, affected by problems such as excessive development of resources, insufficient ecological water supply, fixed river channels, and no flood irrigation, large areas of Populus euphratica forests have declined or even died. More than 9.6 million mu; second, large-scale decline and even death of Populus euphratica forests. The core problem is that under the current natural environmental conditions, Populus euphratica cannot achieve natural regeneration, that is, seed regeneration and root tiller regeneration. Adult and over-mature Populus euphratica forests abound. However, there is no natural regeneration of young and middle-aged forests, and the continuous death of mature and over-mature Populus euphratica forests has caused large-scale decline and even extinction of Populus euphratica forests.
[0005] Due to the current environmental conditions in the Tarim River Basin, excessive development of water resources, insufficient supply of ecological water, reduced overall flow of the river, construction of a large number of reservoirs upstream to store floodwater and a large number of flood irrigation, resulting in the basic stabilization of the river channel and the decline of the groundwater level. An effective

Embodiment 1

[0050] A non-irrigating method for afforestation of Populus euphratica.

[0051] The afforestation site is located at the experimental site of the Populus euphratica Forest Monitoring Station in Lunnan, Luntai County, Korla Prefecture, Xinjiang. The geographical coordinates are: 41°12′49″ north latitude, 84°17′59″ east longitude. The experimental site is 1,200 mu, vertically located on the north bank of the Tarim River, with a width of 200 meters and a length of 4,000 meters. The Populus euphratica forest is a sparse forest, with an average of 1-3 over-mature Populus euphratica trees per mu, with a distance between 20 meters and 1,300 meters. The age of the trees is 40 years Above; in 2015, at the positions of 500 meters, 1000 meters, 1500 meters, 2000 meters, 2500 meters, 3000 meters, 3500 meters and 4000 meters perpendicular to the Tarim River in the test site, 5 parallel pits were dug in each position, and the distance between the pits was 5 meters , to study the situation ...

Embodiment 2

[0063] A non-irrigating method for afforestation of Populus euphratica.

[0064] The site of this afforestation is a non-irrigated afforestation method of Populus euphratica in the Tarim River Basin. It is located at the Populus euphratica forest management and protection station in Yuli County, Korla Prefecture, Xinjiang. The 200-acre site is located on the north bank of the Tarim River. The Populus euphratica forest is a sparse forest, with an average of 1-3 over-mature Populus euphratica per mu, with a distance between 20 meters and 1,000 meters. The age of the trees is more than 40 years; in 2016, the Tarim River A non-irrigation afforestation method of Populus euphratica in the watershed, the specific steps are as follows:

[0065] 1) Select the 200 mu to be located at the Populus euphratica Forest Management and Protection Station in Yuli County, Korla District, Xinjiang, which belongs to the lower reaches of the Tarim River Basin in Xinjiang and belongs to the first-lev...

Abstract

The invention provides an irrigation-free populus euphratica afforestation method. By changing the micro-environment for growth and development of afforestation populus euphratica seedlings, it is guaranteed that the afforestation populus euphratica seedlings can normally grow and develop in the required root system environment, and the survival rate, the preservation rate and the overall afforestation effect of populus euphratica seedling afforestation are improved; and the survival rate and the preservation rate of the populus euphratica seedlings are as high as 80% or above, and the method has great practical value and good application prospects.

Description

technical field [0001] The invention relates to the technical field of tree afforestation, in particular to a method for afforestation of Populus euphratica without irrigation. Background technique [0002] The Tarim River in Xinjiang is located in the extremely arid region of inland Eurasia, with a total length of 1,321 kilometers, a total population of 10.94 million, a total water resource of 44.3 billion cubic meters, and an irrigated area of ​​45.94 million mu. There are 15.3556 million mu of Populus euphratica forest resources in the Tarim River Basin, including 7.9597 million mu of forest land and 7.3959 million mu of sparse forest land, accounting for more than 90% of the total area of ​​Populus euphratica forest in my country. area. Populus euphratica forest plays an important role in climate regulation, windbreak and sand fixation, river stabilization, oasis protection, etc. It is the main body to maintain the balance of the oasis ecosystem in the extremely arid a...
