Abstract:
Taking ‘Qianjiao No.8’ pepper as test material.The effects of different concentrations （0,1.25,2.50,5.00,10.00,20.00 mg?L-1） of nitrite on the quality and trace element content of pepper were studied.The results indicated that spraying a suitable concentration of sodium selenite solution promoted the growth，quality and yield of pepper fruits，increased the selenium content of pepper fruits，reduced the absorption of Cd and Pb，and promoted the accumulation of trace elements in pepper fruits.Compared with the control，the quality of single fruit of pepper treated with selenium was increased by 7.28%，capsaicin content 32.21%，total sugar content 53.22%，vitamin C content 33.95%，and soluble protein content 32.84%.The selenium content increased by 0.002-0.016 mg?kg-1，the Cd content decreased by 39.30%-58.37%，and the Pb content decreased by more than 50%.According to the comprehensive test results，spraying sodium selenite solution in budding period and initial flowering period were beneficial to the formation of pepper quality and yield，and the spraying treatment of 5.00 mg?L-1 had the best effect.
