摘要

利用等离子体技术进行灌溉水处理是提高生产力的一种新方法。在本研究中，等离子体活化水（PAW）的产生作为一个新的农业课题进行了研究。设计并评估了三个水处理系统：第一次通过蒸汽和注入水中产生PAW，第二次通过水面放电产生PAW和第三次通过曝气路径产生PAW。用PAW灌溉生菜种子。6天后测定发芽率和平均发芽时间。8天后还记录幼苗重量和长度超过3cm的幼苗数量。结果表明，PAW对幼苗的发芽率和长度有显著影响。水面放电效果最好。发芽率和长度超过3cm的幼苗数量分别增加了11%和36%。而与对照相比，将等离子体处理的空气注入水中显著减少了长于3厘米的幼苗数量。总之，施用PAW可以改善生菜发芽的某些特性，这取决于PAW系统。

The effects of three plasma-activated water generation systems on lettuce seed germination

Irrigation water treatment using plasma technology is a new approach to improve productivity. In this study the generation of plasma-activated water (PAW) as a novel subject in agriculture is investigated. Three water treatment systems were designed and evaluated: 1st PAW generation from vapor and injection into the water, 2nd PAW generation using electrical discharge on the water surface and 3rd PAW generation in the aeration path into the water. The lettuce seeds were irrigated with PAW. The germination rate and mean germination time were measured after 6 days. The seedlings weight and the number of seedlings with a length of more than 3 cm were also recorded after 8 days. The results showed that PAW had a significant effect on the germination rate and length of seedlings. Electrical discharge on the water surface had the best results. Germination rate and the number of seedlings with a length of more than 3 cm increased by 11 and 36% respectively. While injection of plasma-treated air into the water significantly reduced the number of seedlings longer than 3 cm, compared to the control. In conclusion, the PAW application can improve some attributes of lettuce germination depending on the PAW system.
