Abstract

Abstract: The long-term effect of the improvement of severe saline-alkali soil was still controversial, in this research, in order to improve soil, poplar plantations were planted in different ways in Songnen Plain. The soil environment, photosynthetic process and growth status of poplar were systematically studied. The internal structure of soil structure in severe saline-alkali soil was more uniform, and the looseness, barrier, void, ventilation, permeability and specific surface area were all improved. The elements content of C and Fe in the soil increased by 29.7% and 13.9%, respectively, and the content of Na decreased by 82.4% on average. Therefore, soil colloid cohesion soil fertility was enhanced, and soil salinization was slowed down. The growth rates of photosynthetic rate, respiratory rate, height, DBH, branch number, branch length and crown diameter of poplar were 328%-381%, 98%-153%, 23.8%, 35.3%, 160%, 100%, and 73.5%, and the root growth of the improved Bar foraging ditch was the best. This research has a positive significance for basic data support for biological improvement of degraded saline-alkali soil in Songnen Plain.

Key words: severe saline-alkali soil, soil element, photosynthesis, soil structure, growth conditions
