Abstract Lycium barbarum is an important economic crop in the arid region of Northwest China, and regulation irrigation fertilisation way to improve quality yield . To explore effects water-fertiliser coupling on photosynthesis, under methods based predicted evapotranspiration (ET c ), ET was calculated via reference o ) basis public weather forecasts, water volume determined as a proportion this A field experiment conducted completely randomised experimental design with five volumes (W0 (100% W1 (90% W2 (80% W3 (70% W4 (65% )) three fertiliser application rates (high (FH), medium (FM) low (FL)). The results revealed that chlorophyll content, G sw , C i leaves 100-grain weight fresh fruit increased increasing irrigation, protein fat total sugar content polysaccharide dried fruits first then decreased same level fertilisation, maximum value these indexes reached 70% − 100% At level, E, A, volume, at rate FM. comprehensive evaluation principal component analysis (PCA) optimum treatment both years W0FM (irrigation corresponding range 254.2–309.4 mm, N-P 2 O 5 -K 315-82-135 kg ha −1 which significantly greater 2021 (2022) than CK. daily changes by 46.54% (31.53%), 7.08% (59.26%), 18.55% (10.74%) 34.58% (29.81%), respectively. In (2022), betaine 2.88% (10.11%), 1.56% (10.02%), 8.37% (21.69%), 13.57% (24.81%) 31.39% (71.50%), study may provide theoretical for improving efficiency zone China.
