“…11 In addition, aerated drip irrigation technology can also create a suitable soil water and gas environment for microbial reproduction, increase the number of soil nitrifying bacteria and improve soil enzyme activity. [12][13][14][15] Therefore, aerated drip irrigation simultaneously applies water and oxygen to crops and increases the economic benets of crop production; this method has obvious technical advantages and good application prospects.…”

“…17,18 The successful integration of micro-nano bubble technology and drip irrigation technology has brought new opportunities for the formation of eco-friendly agricultural nanotechnology that will contribute to the sustainable development of agriculture. 19 In summary, the studies of micro/ nanoaerated drip irrigation have been only focus on improving crop yield and quality, 13 promoting crop seed germination, and reducing environmental damage in the process of fertilizer production and use to date. 20 Few studies have focused on the inuence of micro/nanobubbles on the process of drip irrigation system clogging; these studies are still at the initial stage.…”

“…[24][25][26] However, micro/nanobubbles are characterized by superstability, a high mass transfer rate, and strong oxidation, 27,28 which means that they can effectively remove suspended particles in the water, limit microbial activity in irrigation pipelines, further purify irrigation water, and signicantly increase the dissolved oxygen content in irrigation water to promote crop growth. 13 In summary, the study of the emitter clogging process and the evaluation of the inuence of micro/nanobubbles on the anticlogging performance of the drip irrigation emitter will be helpful in further understanding the mechanism by which aerated irrigation inuences the performance of drip irrigation systems, which is of great importance for the application and promotion of aerated drip irrigation technology.…”

“…Moreover, it has a beneficial effect on the growth of organisms, as well as find wider application in the treatment of wastewater [ 19 , 20 ]. Studies also prove that the oxygen micro-nano bubble water accelerates the growth of plants, increases blooming, has a bactericidal effect and improves the soil structure [ 21 ]. In turn, the ozone micro-nano bubble water has bactericidal and preserving effect; it is used in wastewater treatment, as well as in medicine and stomatology [ 22 ].…”

The paper presents the experimental studies on the effect of the water containing micro-nano bubbles of various gases on the physico-mechanical properties of lime-cement mortars. In total, 7 types of mortars were prepared: with water containing the micro-nano bubbles of O2, O3 or CO2 as 50% or 100% substitute of ordinary mixing water (tap water) and the reference mortar prepared using tap water. In order to determine the influence of water with micro-nano bubbles of gases, the consistency of fresh mortar and the physical properties of hardened mortar, i.e., specific and apparent density, total porosity, water absorption by weight and capillary absorption, were established. The mechanical strength of the considered mortars was studied as well by conducting the tests for flexural and compressive strengths following 14, 28 and 56 days. Reduced workability and capillary absorption were observed in the modified mortars within the range of 0.9–8.5%. The mortars indicated an increase in the flexural strength after 28 days ranging from 3.4% to 23.5% and improved compressive strength in 1.2–31%, in comparison to the reference mortar. The conducted studies indicated increased flexural and compressive strengths along with the share of micro-nano bubbles of gases in the mixing water.

“…Lower oxygen content of soil inhibits root respiration and growth (Greenway et al, 2006). Supplying sufficient oxygen to the root zone of plants promotes absorption of soil moisture and nutrients, thereby increasing crop yield (Du et al, 2018;Sang et al, 2018;Zhou et al, 2019). The germination rate of barley was 58% in 17 hours of the experiment after applying oxygen nanobubble water that has 15-25% higher DO than distilled water, thereby showing a 28% increase compared to applying distilled water (Liu et al, 2016).…”

Background and objective: The nanobubbles remain stable in water, and it increased dissolved oxygen (DO) in the water that promotes the seed germination and the plant growth. We evaluated the seed germination and growth of sprouts (radish, wheat, and barley) and leafy vegetables (red mustard and pak choi) when irrigated with various DO of nanobubble water (NB).Methods: The oxygen NB was generated by surface friction and treated in 4 levels: NB 0% (control, DO 9.21 mg·L-1), NB 20% (DO 15.40 mg·L-1), NB 33% (DO 20.93 mg·L-1), and NB 100% (DO 39.29 mg·L-1).Results: The root length of radish and wheat increased more in NB 33% than the control plot. The fresh weight increased in NB 33% compared to the control plot in radish and wheat, and both fresh and dry weight increased more in NB 20%, NB 33%, and NB 100% than the control plot of barley. The leaf length and width of red mustard decreased more in NB 33% and NB 100% than the control plot and NB 20%, which indicated the leaf compactness. The fresh and dry weight of shoot and root increased more in NB 100% than the control plot in red mustard. In pak choi, the shoot fresh weight increased more in NB 100% than the control plot. In leafy vegetables, the germination rate of red mustard in NB 100% was higher than the control plot, however, it was not significantly different between oxygen NB plots in sprout vegetables.Conclusion: The results showed that the root growth and biomass increased after applying NB 33% in sprout vegetables. The leaf growth properties as the number of leaves and leaf size were not significantly different or decreased in NB treatments compared to control plots, but NB 100% (DO 39.29 mg·L-1) effectively increased the root growth and plant biomass in leafy vegetables.
