摘要
等离子体技术在农业生产、生物医学、环境保护等领域有着广泛的应用前景。论文采用多针-板电极制备等离子体活化水装置、板-板电极等离子体直接处理马铃薯装置,对比研究了不同放电功率下等离子体活化水、直接等离子体处理对马铃薯生长特性及产量的影响。2种装置均呈丝状放电,且放电功率与外施电压正相关;当最佳放电功率匹配时,等离子体活化水、直接等离子体处理均能显著改善马铃薯生长特性及产量。等离子体活化水的放电功率为53 W时,马铃薯植株高度、茎粗、鲜重、叶绿素质量分数及产量分别提升了6.4%、18.9%、25.9%、31.7%及17.5%;直接等离子体处理马铃薯的放电功率为8 W时,植株的各参数值增幅均在10%以上。研究结果表明:放电功率变化时,等离子体活化水的理化参数(pH值、氧化还原电位、电导率、过氧化氢、硝酸根离子、亚硝酸根离子)变化显著;随着放电功率的提升,直接等离子体处理的马铃薯吸水率先增长后下降,种皮刻蚀逐渐明显。论文的研究可为DBD等离子体与活化水在农业生产领域应用提供参考。
Plasma technology has broad applications in agricultural production,biomedicine,environmental protection and other fields.In this paper,the devices that multi-needles-plate electrodes are adopted to prepare plasma activated wa-ter and plate-to-plate electrodes are adopted to directly treat potato are used to compare the effects of plasma activated water and direct plasma treatment on potato growth characteristics and yield under different discharge powers.Both de-vices exhibit filamentous discharge,and the discharge power positively correlates with the external voltage.When matched with their respective optimal discharge powers,plasma activated water and direct plasma treatment can signifi-cantly improve potato growth characteristics and yield.When the discharge power of the plasma activated water device is 53 W,the plant height,stem diameter,fresh weight,chlorophyll mass fraction and yield of potato plants increase by 6.4%,18.9%,25.9%,31.7%and 17.5%,respectively.When the discharge power of the direct plasma treatment potato device is 8W,the increase of all parameter values of the plant is more than 10%.The results show that the physicochemical param-eters(such as pH value,oxidation reduction potential,electrical conductivity,H_(2)O_(2),NO_(3)^(-),NO_(2)^(-))of plasma activated water change significantly when the discharge power changes.With the increase of discharge power,the water absorption of direct plasma treated potatoes first increases and then decreases,and the seed surface etching gradually becomes obvi-ous.This study in the paper can provide a reference for the application of DBD plasma and activated water in the field of agricultural production.
