There is Great Potential to Develop the Cyperus esculentus as a New Feed Resource in China
Cyperus esculentus,which was a kind of annual herb that integrates grain oil,feeding and biochemical application,had a good development and application prospects.The tuber had high oil and starch content,moderate fiber content,the protein content was similar to grain.It was rich in essential fatty acids,dietary fiber,flavonoids and sterols.It had several bio-activities such as anti-oxi-dation,lowering blood sugar,regulating lipid metabolism and antibacterial function.Therefore,it could be provided as a good develop-ment potential functional food and feed.The biomass of stems and leaves on the ground was large,which could be used to produce green feed,hay and silage feed for herbivores,pigs,geese and other livestock.Cyperus esculentus had strong adaptability and it was suitable for developing and planting in saline-alkali land and desert.In this paper,the oil production and feeding value of tubers,stems and leaves of Cyperus esculentus were reviewed,in order to promot the development of large-scale planting and application technolo-gy combining"agronomy,agricultural machinery and agricultural technology",support agricultural land such as saline-alkali land and desert,so as to alleviating food security.
