Research Progress and Challenge of High-Yield Cultivation of Peanut in Saline-Alkali Lands
Saline-alkali lands are valuable reserve resources of cultivated land,further improving yield of crops in these lands is a priority task in agricultural production in China.Peanut is the main cash and oil crop in China,exploring and utilizing saline-alkali lands for high-yield cultivation of peanut is of great significance to increasing agricultural efficiency and farmers'income and guaranteeing edible oil security.This paper brief-ly described the scientific principle of saline-alkali land improvement,summarized the research progress on al-leviating salt and alkali stresses and promoting high yield of peanut in saline-alkali lands from molecular regu-lation mechanisms of peanut resistant to salt stress,physical and chemical improvement measures and agro-nomic management measures based on some field experiments conducted by the peanut research team in Shan-dong Academy of Agricultural Sciences,and pointed out the challenges of further improving peanut green pro-duction.This study could provide strong theoretical bases and technical supports for green and efficient produc-tion of peanut in saline-alkali lands,which have key reference significance for guaranteeing national food and oil security and improving regional agroecological environment.
