Effects of Ground Covers on Photosynthetic Characteristics,Antioxidant Indexes and Yield of Lycium barbarum
摘要
Abstract
The paper aims to clarify the influence of different mulching materials on the photosynthetic characteristics,physiological characteristics and yield of Lycium barbarum in Ningxia region,and to provide theoretical basis and technical support for high yield,stable yield and high quality of L. barbarum in Ningxia region. A randomized block group experimental design was adopted,with four treatments:straw mulch (SM),horticultural ground mulch (HM),black mulch (BM),and natural grass mulch (CK),to study the change patterns of photosynthetic parameters,antioxidant characteristics and yield of L. barbarum leaves under different mulching materials. Mulching measures had significant effects on photosynthetic parameters,antioxidant enzymes,malondialdehyde content and yield of L. barbarum leaves. Among them,compared with CK treatment,the net photosynthetic rate (Pn) was significantly increased by 16.69% under HM treatment. At fruit bloom stage,superoxide dismutase (SOD) was significantly increased by 9.38% under HM treatment compared to CK treatment. At the full fruit stage,the malondialdehyde (MDA) content of CK treatment reached the maximum compared with other treatments. The yield of L. barbarum in HM treatment reached 1138.20 kg/hm2,which was significantly higher than that in other treatments. Under HM treatment,the activity of antioxidant enzymes was higher and the content of MDA was the lowest,which could resist the external adverse environmental stress to a certain extent. Compared with CK,the contents of flavonoids,polysaccharides and betaine in L. barbarum under HM treatment were significantly increased by 102.86%,19.03% and 75.93% . Horticultural ground cloth cover can effectively ensure higher values of photosynthetic parameters,antioxidant enzyme activity,improve the capture of light energy,absorption,and promote material transformation of L. barbarum to promote the photosynthesis of L. barbarum,and promote the transformation of dry matter,thus improving the yield and quality of L. barbarum.关键词
