Abstract:

To select suitable mulching materials for watermelon cultivation, white film, mushroom residue, liquid film and black grass proof non-woven fabric were selected for mulching cultivation, and their effects on photosynthetic characteristics, yield and quality of watermelon were comprehensively compared. The results showed that: (1) in all treatments, the covering effect of black grass proof non-woven fabric was the best, the fruit yield and the contents of soluble solids and Vc were significantly higher than those of other treatments, the net photosynthetic rate (Pn), stomatal conductance (Gs) and transpiration rate (Tr) of leaves were significantly higher than those of other treatments, and the intercellular CO2 concentration (Ci) was significantly higher than that of the control, while the water vapor pressure deficit (Vpd) was significantly lower than that of other treatments; (2) the correlation analysis showed that there was an extremely and significantly positive correlation between watermelon yield and Pn, Tr, Vpd, and between Pn and Tr. In general, the black grass proof non-woven fabric could be used as a suitable mulching material for watermelon cultivation.

Key words: watermelon, mulching material, photosynthetic characteristics, yield, quality
