摘  要:
合理的营养液消毒技术是无土栽培蔬菜取得优质高产的保证。微酸性电解水作为高效、低残留的杀菌剂已应用到许多领域,其能否应用于无土栽培营养液消毒需要进一步验证。以台湾长叶空心菜为试材,研究了营养液不同浓度电解水有效氯对其产量和品质的影响,探索利用微酸性电解水进行水培营养液消毒的可行性。结果表明:在水培条件下,随着营养液中有效氯浓度的增加,空心菜的产量(鲜重、干重、株高、茎粗)和品质指标(可溶性糖含量、维生素C含量)均表现出先增大后减小趋势。总体而言,空心菜的产量指标对有效氯浓度反应比较敏感,使用微酸性电解水消毒后的营养液在回收利用前需要进行有效氯浓度检测,若有效氯浓度过高则可以通过搅拌扰动的方法促进其分解,将其控制在合理的范围内,以免其对空心菜的生长产生不利影响。

摘  要:
Reasonable techniques of nutrient solution disinfection were the guarantee of high quality and yield vegetable production under soilless.The acidic electrolyzed water was applied in many fields as an effective fungicide but low residue.However,the applicability of acidic electrolyzed water to nutrient solution disinfection should be further tested.In order to explore feasibility of nutrient solution disinfection using acidic electrolyzed water,the effect of available chlorine concentration on the yield and quality of water spinach was studied.The results showed that the yield(fresh weight,dry weight,plant height,stem diameter)and quality(soluble sugar,vitamin C)indexes were first increased,with the increasing of available chlorine concentration supplied to the nutrient solution,and the decreased.Overall,the yield index of water spinach was sensitive to available chlorine concentration.Before the disinfected nutrient solution reused,the available chlorine concentration in the nutrient solution should be detected to maintain within a reasonable range by blending or diluting the nutrient solution.That would be avoiding the negative effect of available chlorine concentration on the growth of water spinach.
