Abstract: The paper aims to investigate the influence of biogas slurry spraying on yield and plant physiology of protected cultivation melon, a facility cultivation experiment was performed that taking ‘Xizhoumi 17’ as material. The results showed that the concentration of biogas slurry spraying significantly effected weight of per fruit, chlorophyll content, soluble protein and soluble sugar content of melon leaves. The activities of peroxidase (POD) and superoxide dismutase (SOD) affected significantly by content of biogas slurry spraying, but catalase activity (CAT) showed no significant influence. Single fruit weight and leaf nutrient content were positively correlated, and negatively related with the activities of antioxidant enzymes. Under biogas slurry concentration 75%, the biggest single fruit weight reached to 2.70 kg. With the increase of concentration of biogas slurry spraying, POD and SOD activity of leaves had a descending trend; CAT had no obvious change rule. In conclusion, improving leaf nutrition and reducing the activity of antioxidant enzymes could increase yield of melon, and the spraying concentration 75% more appropriate.
