| Abstract: |
| In…the…field， under…different…irrigation…conditions， the…secondary…substances…of…Lycium barbarum…
accumulation…were…studied.…The…results…showed…that…adequate…water…supply…was…conducive…to…the…accumulation…of…total…
sugar…and…Vc， and…drought…treatment…was…conducive…to…the…accumulation…of…betaine…and…carotenoids， but…not…conducive…
to…the…accumulation…of…Vc， flavonoids…and…sugar.…Correlation…analysis…showed…that…there…was…positive…correlation…between…
polysaccharides…content…and…betaine…content， no…significant…negative…correlation…between…betaine…content…and…carotenoids…
content， significantly…positive…correlation…between…betain…contente…and…total…sugar…content.…There…was…very…significantly…
negative…correlation…between…moisture…content…and…polysaccharide…/…Vc…content， significantly…negative…correlation…
between…moisture…content…and…polysaccharide…/…flavone…content， negative…correlation…between…moisture…content…and…
polysaccharide/betaine…content， negative…correlation…between…moisture…content…and…polysaccharide/carotenoid…content.…
Resurts…indicated， proper…irrigation…could…not…only…guarantee…the…quality…of…L. barbarum L.， but…also…decreased…the…output…
reduction…of…L. barbarum…L.…In…this…experiment， the…reasonable…frequency…of…irrigation…for L. barbarum L.， …growing…period…
was…2-3…times， the…amount…of…water…per…667…m 2 …was…75m 3 . |
