摘  要:
本实验研究基于不同营养液水培黄瓜,使用不同浓度的霍格兰营养液(稀释倍数分别为20%、40%、100%、150%、200%)水培黄瓜。培养一个周期后,利用营养液消毒装置测定其消毒效果以及水培黄瓜的生长情况。结果表明,该消毒装置对营养液余液最佳消毒条件为:紫外强度30 W、营养液浓度150%、消毒时间200 s。研究结果对营养液余液的回收利用具有非常重要的意义。

摘  要:
In this experiment, based on different nutrient solutions of water cultured cucumbers, different concentrations of Hogan's nutrient solution(with 20%, 40%, 100%, 150%, and 200% dilution ratios) were used to hydroponics cucumber. After one cycle of cultivation, the effect of disinfection by the nutrient solution disinfection device and the growth of cucumber with hydroponics were measured. The results showed that the optimal disinfection conditions of the sterilization device for the remaining nutrient solution were: ultraviolet intensity of 30 W, nutrient solution concentration of 150%, and disinfection time of 200 s. The result has great significance for the recovery and utilization of nutrient residual liquid.
