摘要：

为探明雾化调控对宁夏枸杞微生态环境、叶片生理特性及产量品质的影响，2024年在宁夏银川市镇北堡开展试验，设置空白对照(CK)、雾化调控(T1)和常规栽培(T2)3个处理，分析不同处理下枸杞叶片生理特性及产量品质的变化趋势。结果表明，与CK相比，T1处理的枸杞净光合速率(Pn)、气孔导度(Gs)、蒸腾速率(Tr)及PSⅡ最大光化学效率(Fv/Fm)、PSⅡ潜在最大光合能力(Fv/Fo)、光合机构性能综合参数(PI)、PSⅡ光能捕获效率(ABS/RC)分别增加72.9%、29.3%、26.9%和28.6%、24.4%、72.2%、30.6%；与CK相比，T1处理的相对湿度、土壤湿度分别增加4.7%、35.6%，环境CO2浓度、空气温度(At)、叶片温度、土壤温度较CK分别下降9.8%、4.2%、5.9%、8.8%；枸杞夏果期时，T1处理显著增加了枸杞类黄酮、多糖、甜菜碱含量和总干果产量、百粒重，与CK相比分别增加43.5%、64.7%、25.0%、34.2%、15.7%。相关性分析表明，枸杞产量与Tr、Fv/Fo、PI、土壤湿度、甜菜碱含量呈显著正相关(P<0.05)，与枸杞Pn、Gs、Fv/Fm、ABS/RC达到极显著正相关(P<0.01)，与枸杞类黄酮、多糖含量呈极显著正相关(P<0.01)。主成分分析综合得分为T1>T2>CK。雾化调控通过缓解高温胁迫的生理抑制效应，在有机栽培体系中展现出显著提质增效作用，建议作为宁夏枸杞标准化生产的关键调控技术推广应用。

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.
