A Renewal Method for Seeking and Removing the Roots of Populus euphratica in Arid Desert Area

Abstract

The invention discloses an update method for finding and removing roots of Populus euphratica in an arid desert area, comprising the following steps: 1) selecting an update area; 2) specifying an update time; 3) predicting the direction of the root system of Populus euphratica and selecting a reasonable site for root removal; 4) delaying time Backfill. Compared with the existing annular ditch renewal technology, the renewal method provided by the present invention has the following advantages: the time for the renewal project is regulated, and the construction in the windy season is avoided. At the same time, due to the new sand source formed by man-made soil disturbance, it avoids the windy season and reduces the amount of sand and soil transported by wind erosion; selectively determine the renewal position and rationally allocate the density of Populus euphratica forest; the engineering quantity of this method is newer than that of the circular ditch The reduction is more than 78%, saving manpower and material resources; the method of the invention is simple and easy to grasp, quick and effective, and has strong practicability and operability.

Description

technical field [0001] The invention relates to the technical field of desert vegetation restoration in Xinjiang, in particular to a root-seeking and root-cutting method for Populus euphratica in arid desert areas. Background technique [0002] Populus euphratica ( Populus euphratica ), also known as poplar heterophyllum, is a medium-sized deciduous natural tree and the oldest tree species in the genus Populus. It is mainly distributed in western my country, Central Asia, West Asia, and the Mediterranean region. The diameter of Populus euphratica can reach 1.5 meters. The wood is slender and soft, and the leaves are broad and fragrant. Populus euphratica is drought-resistant and flood-resistant, and its life is tenacious. It is one of the rare tree species in nature. Populus euphratica can be up to 200 years old, with a straight trunk, 10-15 meters high, and a thin shrub shape. Its leaves are peculiar. Because it grows in the extremely arid desert area, in order to adapt to...

Problems solved by technology

However, during the regeneration process of the natural Populus euphratica forest, due to the rich vegetation and complex terrain in the Populus euphratica forest, it is difficult for existing machinery to enter, and the manual excavation of the ring-shaped ditch requires a large amount of work. Root distribution is sparse, and trenching in these directions is often ineffective

In the regeneration of Populus euphratica in larger forest gaps, due to the construction restrictions of the circular ditch, the distance between the ditch and the parent tree is limited, and it is difficult to advance to a long distance, and the regeneration of large gaps in Populus euphratica forest is slow

In summary, the current regeneration method requires a large amount of engineering, strong soil disturbance, and low regeneration efficiency.
