香蕉组织膜邻苯二酚电极的研究

邻苯二酚现有的分析方法是基于苯酚和多酚与某些氧化剂的显色反应,用光度法进行测定,这些方法专属性较差,且分析中需从其它的苯酚化合物中分离儿茶酚,常伴有一定的损失,易导致测定误差。鉴于香蕉组织中含有丰富的多酚氧化酶,本文以香蕉组织偶合氧电极,研制成香蕉组织膜邻苯二酚电极,其原理基于如下的反应式:2(?)+O_2(?),用氧电极测耗氧量,从而间接测定邻苯二酚含量。实验中制成静态和流通二种型式,取得了较好的结果。

Effects of Application of Cassava Alcohol Anaerobic Fermentation Liquid and Mulching of Film on Overwintering and Next Year's Growth and Yield of Banana

The effects of application of cassava alcohol anaerobic fermentation liquid and mulching of film on overwintering and next year's growth and yield of banana were investigated in this study.The results showed that the application of cassava alcohol anaerobic fermentation liquid with COD concentration of 1 200-2 000 mg/L(900 m^3/hm^2) and mulching of film significantly increased the soil organic matter and available potassium contents in banana orchard,improved the cold resistance of banana seedlings,increased the pseudostem height,pseudostem circumference,green leaf number and chlorophyll content of next year's banana seedlings,brought the flower bud emergence period and harvest period forward,and significantly increased the yield per plant.
