Method for improving survival rate of directly-planted seedling and transplanting seedling of haloxylon plant in desert or semi-desert environment

摘要

The present invention belongs to the field of forest ecological culture and discloses a method for improving the survival rate of a directly-planted seedling and a transplanting seedling of a haloxylon plant in desert or semi-desert environment. In desert and semi-desert areas meeting a certain condition, the base part of the stem of the directly-planted seedling or the transplanting seedling of the haloxylon plant is protected by using a cylindrical pipe or hollow bullet-shaped pipe of a certain specification from damage or even death caused by stress factors such as a ground surface layer at high temperature. Through the present invention, the survival rate of a directly-planted seedling and a transplanting seedling of the haloxylon plant under extremely stress conditions in the desert and semi-desert areas can be obviously improved, and the average improvement rate is over 50%, the quick growth and development of individuals are promoted and the annual mass growth is increased. The present invention is characterized by strong operability, good repeatability, high efficiency and simple method, and the method has a very great significance for the large-scale ecological restoration and reconstruction of haloxylon plants in the desert and semi-desert areas.
