Abstract: In this experiment, three nutrient solution concentrations and three spray intermittent frequencies are used to treat coriander plants during the growth period. The growth experiment of coriander is carried out in the multi span greenhouse of the horticultural experiment station of Tarim University from 2021 to 2022. It is found that the comprehensive indexes of coriander were better under the treatment of 50%～75% and 75%～100% nutrient solution concentrations and 5 min and 7 min spray intermittent frequencies.The yield of coriander is the highest under the treatment of 50%～75% concentration nutrient solution and 5 min spray intermittent frequency.
