Adaptability Study of Cyperus Esculentus in the Desert Area of Gansu Hexi Corridor
In order to address the land desertification in Jiuquan City and increase oil plants production capacity,screening for new varieties of Cyperus esculentus with strong ecological adaptability in the arid desert area of Hexi,Gansu Province was conducted.In 2023,5 varieties of Cyperus esculentus including Nongan early seedling,Nongan late seedling,Hainan Cyperus esculentus,Hebei Cyperus esculentus and Inner Mongolia Cyperus esculentus underwent adaptability trials in marginal sandy areas near Jiuquan City.The results indicated that the 5 varieties of Cyperus esculentus exhibited generally consistent performance during the growth period in the Suzhou District of Jiuquan City,demonstrating commend ableadapt ability.The nutritional components of the tubers from the five trial varieties were largely similar,characterized by high starch content,elevated levels of crude protein,and ether extract with oleic acid content ranging between 674.5 to 708.0 g/kg.Tuber yields for the five trial varieties ranged from 6 850.35 to 7 312.8 kg/ha,with corresponding incomes from mechanized plantingranging from 31 725.95 to 34 963.10 Yuan/ha.The comprehensive ecological adaptability showed that the 5 tested varieties were suitable for large-scale popularization and planting in Jiuquan City and desertification areas.
