Abstract:
Using Lycium ruthenium at full fruit stage as test material,five concentrations of KH2PO4(1‰,2‰,3‰,4‰ and 5‰) were treated by foliar spraying.The hundred weight of fresh fruit,the yield per plant,fruit diameter,polysaccharide content,total sugar content,vitamin C content,total acid content,anthocyanin content,flavonoid content and chlorophyll content of L.ruthenium were measured,and with sprayed water as control,In order to provide reference for improving the yield and quality of Lycium ruthenicum under cultivation conditions.The results showed that foliar spraying with KH2PO4 could increase the hundred fresh fruit weight,the yield per plant,polysaccharide content,total sugar content,vitamin C content,total acid content,anthocyanin content,flavonoid content and chlorophyll content,but had no significant effect on fruit diameter and the fruit type.The yield per plant,hundred fresh fruit weight,vitamin C content,total acid content,anthocyanin content,chlorophyll a content and chlorophyll b content were the highest when spraying 2‰ KH2PO4 solution,while the polysaccharide content,total sugar content,and carotenoid content were the highest when spraying 3‰ KH2PO4 solution.After comprehensive analysis,the best application scheme for L.ruthenium is spraying 2‰ KH2PO4 solution once a month and begin at the leaf development period until the fruit mature.
