Abstract: Lower and higher nutrient solution concentration were not benefit for muskmelon plant growth and development in soilless medium culture under protected field. The effects of lower and higher nutrient solution concentration on net photosynthetic rate of leaves were resulted in non-stomatal limitation, which related to photosynthetic activity descent of mesophyll cell. The EC value of optimization nutrient solution concentration was expounded in order to improve fruit quality and yield, 1.40 mS/cm from planting to pollination, 1.56 mS/cm from pollination to reticulation formation, 2.63 mS/cm from reticulation formation to fruit maturity, respectively. In muskmelon cultural practice, fertilizer application should based on development stage, the ratio of N and K was 1.05∶1 from planting to vegetable growth stage, 0.53∶1 from fruit setting stage to harvest.

Key words: Muskmelon, Nutrient solution concentration, Photosynthetic characteristic, Fruit quality, Soilless medium culture
