Abstract: To explore the effect of activated water on wheat growth and root activity, a combination of indoor hydroponic and field experiment was set up by using Xiaoyan 22 as the test variety, and the effects of groundwater after activation treatments such as de-electronation, magnetization, de-electronation before magnetization, magnetization before de-electronation etc. On seed germination rate, plant height, leaf chlorophyll content(SPAD), aboveground and underground biomass, root activity, root configuration and grain yield of wheat were studied. The results showed that under field condition, at the same irrigation level(180 mm), the increase in plant height and dry matter mass from jointing to filling stage of wheat irrigated by activated water was significantly higher than that of groundwater irrigation. And the grain yield of wheat irrigated with activated water increased by 1.0%-17.8% compared with groundwater irrigation treatment. Laboratory studies found, compared with groundwater treatment, activated water cultivation could increase the germination rate of wheat seeds(4.0%-64.3%) and leaf chlorophyll content(8.9%-17.3%), while the aboveground dry matter mass, root dry matter mass and root activity increased significantly by 59.6%-102.4%, 35.9%-90.9% and 75.8%-194.2%, respectively. And root configuration index(total root length, total root surface area, total root volume, total root tips, etc.) also increased accordingly. In summary, laboratory hydroponic and field experiments had shown that various types of activated water could promote wheat growth, enhance root activity, improve root configuration, increase leaf chlorophyll content, promote the accumulation of plant dry matter, and thereby raise yield.
