摘要: 为研究不同沼液浓度叶面喷施对设施甜瓜产量和植株生理的影响,以设施栽培条件下‘西州密17号’甜瓜为试材,采用不同浓度沼液进行叶面喷施研究。试验结果表明,沼液浓度对甜瓜单瓜重、叶片中叶绿素、可溶性蛋白、可溶性糖含量均有显著影响,对叶片过氧化物酶(POD)有显著影响,而对过氧化氢酶(CAT)和超氧化物歧化酶(SOD)无显著影响。单瓜重与叶片营养含量呈正相关关系,而与抗氧化酶活性呈负相关关系。叶面喷施沼液能够有效提高单瓜重,并促进叶片营养的合成;以沼液浓度75%时,单瓜重最大,为2.70 kg。随着沼液喷施浓度的增加,甜瓜叶片中POD、SOD活性呈下降趋势,CAT活性变化无明显规律。综合来看,沼液喷施通过提升叶片营养含量、降低叶片抗氧化酶活性达到增产目的,且以喷施浓度75%较为适宜。

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.
