The micro and nano bubble (MNB) technology, due to its promising features and advantages, has become increasingly popular in agriculture. MNB-treated water positively impacts plant growth, especially when it is treated with a combination of gas-like carbon dioxide (CO), injected through the MNB generator. Therefore, this study used MNB water with CO that are small bubbles of nanometer and micrometer diameters having several unique physical properties that make them useful for water treatments. This research evaluates the effect of MNBs and CO-treated water on leafy vegetable Amaranth green (Amaranthus viridis). The experiment divided the Amaranth plants into three major groups, G1, G2, and G3, irrigated by MNB water with dissolved CO, MNBs with only Air, and simple tap water, respectively. The first treatment group (G1) (MNBs with CO) was further divided into three sub-divisions, i.e., G1A, G1B, G1C, and the second treatment group G2 (MNBs with Air) was divided into three sub-groups, i.e., G2A, G2B, and G2C, while the third group G3 with only one category as only controlled group. These sub-divisions of treatment groups G1 and G2 were done to investigate the impact of MNBs and CO treated water with different time durations. For example, in G1A, the water treatment with MNBs and CO was kept five minutes, for G1B 10 minutes, and G1C 15 minutes. Similar method was adopted for G2 as well. According to the results, water treated with MNB and CO has a significant (90%) impact on the Amaranth germination rate and plant growth. Specifically, pots irrigated with the MNBs + CO-treated water showed better germination and plant growth rate than the MNBs + Air treated water. Overall, both treatment groups, G1 and G2, showed significantly higher impacts than the CK groups (simple water). Further, this experiment showed that the 10 and 15 minutes treatment of water (G1B, G1C and G2B, G2C) increased the stem height and root size compared to the 5 minutes treated water (G1A, G2A). This study concludes that the water with MNBs has a positive impact on the vegetables and can be an effective technology to improve crop yield.
微纳米气泡（MNB）技术由于其有前途的特点和优势，在农业中越来越受欢迎。MNB 处理过的水对植物生长有积极影响，特别是当它与气体二氧化碳（CO）结合处理时，通过 MNB 发生器注入。因此，本研究使用具有 CO 的 MNB 水，这些 CO 是具有纳米和微米直径的小气泡，具有多种独特的物理特性，使其可用于水处理。本研究评估了 MNB 和 CO 处理水对叶菜苋菜绿（Amaranthus viridis）的影响。实验将苋菜植物分为三组，G1、G2 和 G3，分别用含有溶解 CO 的 MNB 水、仅含空气的 MNB 和普通自来水灌溉。第一处理组（G1）（含 CO 的 MNB）进一步分为三个亚组，即 G1A、G1B、G1C，第二处理组 G2（含空气的 MNB）分为三个亚组，即 G2A、G2B 和 G2C，而第三组 G3 只有一个类别，作为仅有的对照组。这些处理组 G1 和 G2 的细分是为了研究不同时间长度的 MNB 和 CO 处理水的影响。例如，在 G1A 中，用 MNB 和 CO 处理水保持五分钟，在 G1B 中保持十分钟，在 G1C 中保持十五分钟。G2 也采用了类似的方法。根据结果，用 MNB 和 CO 处理的水对苋菜的发芽率和植物生长有显著（90%）的影响。具体来说，用 MNBs+CO 处理水灌溉的花盆的发芽率和植物生长速度明显优于用 MNBs+空气处理水灌溉的花盆。总体而言，处理组 G1 和 G2 比 CK 组（普通水）的影响显著更高。此外，该实验表明，与 5 分钟处理的水（G1A、G2A）相比，水的 10 分钟和 15 分钟处理（G1B、G1C 和 G2B、G2C）增加了茎高和根大小。本研究得出的结论是，用 MNB 处理的水对蔬菜有积极影响，可以成为提高作物产量的有效技术。
