Abstract:
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.
