Research Progress on Physiological Mechanism of Salt Alkali Tolerance and Germplasm Screening in Soybean
The saline and alkaline land in China is large and widely distributed,and the secondary salinization problem is becoming increasingly serious.The increasing area of saline and alkaline land has become an important factor restricting the development of agriculture,therefore the selection and breeding of crop varieties that can adapt to the adversity is the most important way to exert the production potential of saline and alkaline land.Soybean is a moderately salt-tolerant plant,the fourth largest crop in the world,and an important food,economic and feed crop in China.It is of great significance to screen and cultivate high-quality saline-tolerant soybean varieties to rationally utilize saline-alkaline land and promote the sustainable development of China's agriculture.This paper summarized the current status of soybean salinity tolerance research from four aspects:the type of solonchak and the harm to plants,the harm of solonchak to soybean growth,the physiological mechanism of soybean salinity tolerance,and the screening of salinity-tolerant soybean germplasm,aiming to provide a theoretical basis for the selection and breeding of new salinity-tolerant varieties of soybean and breeding ideas.
