The present invention discloses a pharmaceutical composition comprising an active pharmaceutical ingredient and an available pharmaceutical excipient; The active pharmaceutical ingredient is 3-((1H-pyrazolo[3,4-b]pyridin-5-yl)ethynyl)-4-methyl-N-(4-((4-methylpiperazin-1-yl)methyl)-3-(trifluoromethyl)phenyl)-benzamide, or its pharmaceutical acceptable salt; The available pharmaceutical excipients includes diluents and lubricants. The pharmaceutical composition can effectively improve the bioavailability of the alkynyl compound, has good dissolution and stability, and improve the drug safety.

Abstract: 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.
