Abstract

Abstract:

To explore the effects of atomization regulation on the micro-ecological environment, leaf physiological characteristics, yield and quality of Ningxia Lycium barbarum, experiments were conducted in Zhenbeipu, Yinchuan City, Ningxia in 2024. Three treatments were set up: blank control (CK), atomization regulation (T₁), and conventional cultivation (T₂). The changes in leaf physiological characteristics, yield and quality of L. barbarum under different treatments were analyzed. The results showed that compared with CK, the net photosynthetic rate (Pn), stomatal conductance (Gs), transpiration rate (Tr), maximum photochemical efficiency of PSⅡ (Fv/Fm), potential maximum photosynthetic capacity of PSⅡ (Fv/Fo), comprehensive parameter of photosynthetic apparatus performance (PI), and light energy capture efficiency of PSⅡ (ABS/RC) of L. barbarum under T₁ treatment increased by 72.9%, 29.3%, 26.9%, 28.6%, 24.4%, 72.2%, and 30.6%, respectively. Compared with CK, the relative humidity and soil moisture under T₁ treatment increased by 4.7% and 35.6% respectively, while the environmental CO₂ concentration, air temperature (At), leaf temperature and soil temperature decreased by 9.8%, 4.2%, 5.9% and 8.8% respectively; During the summer fruiting period of L. barbarum, T₁ treatment significantly increased the content of flavonoids, polysaccharides, betaine, total dry fruit yield, and 100-grain weight (GW) of L. barbarum, which increased by 43.5%, 64.7%, 25.0%, 34.2%, and 15.7%, respectively, compared with CK. Correlation analysis showed that the yield of L. barbarum was significantly positively correlated with Tr, Fv/Fo, PI, soil moisture and the content of betaine (P<0.05), was extremely significantly positively correlated with Pn, Gs, Fv/Fm, and ABS/RC (P<0.01), and was extremely significantly positively correlated with the content of flavonoids and polysaccharides (P<0.01). The comprehensive score of principal component analysis was T₁>T₂>CK. Atomization regulation showed a significant effect of improving quality and increasing efficiency in the organic cultivation system by alleviating the physiological inhibitory effect of high-temperature stress. It is recommended to be promoted and applied as a key regulation technology for the standardized production of Ningxia L. barbarum.
