水培条件下氢肥对小白菜与生菜生长及光合作用的影响
Hydrogen Fertilizer Promotes the Growth and Photosynthesis of Pakchoi and Lettuce Under Hydroponic Conditions
摘要
Abstract
Pakchoi and Italian lettuce were cultured under hydroponic conditions in the nutrient solution with or without(control)hydrogen fertilizer.The growth indexes,chlorophyll content,photosynthetic parameters,and biomass of pakchoi and lettuce were measured.The results showed that compared with the control,the hydrogen fertilizer treatment had increased leaves of pakchoi and increased SPAD values and chlorophyll content of pakchoi and lettuce leaves.The plant height,crown width,and root length of pakchoi in the hydrogen fertilizer treatment were lower than those in the control,and the crown width of lettuce in the hydrogen fertilizer treatment was lower than that in the control,while there was no significant difference in the plant height and root length of lettuce between the two treatments.The aboveground fresh weight and dry weight of pakchoi in the hydrogen fertilizer treatment were significantly improved,while there was no significant difference in lettuce biomass,indicating that hydrogen fertilizer promoted the growth and improved the biomass of pakchoi.The net photosynthetic rates and intercellular carbon dioxide concentrations of pakchoi and lettuce leaves,as well as the transpiration rate and stomatal conductance of lettuce,in the hydrogen fertilizer treatment were significantly higher than those in the control.After hydrogen fertilizer treatment,the chlorophyll fluorescence parameters of pakchoi and lettuce increased slightly but not significantly.The results of comprehensive analysis showed that hydrogen fertilizer increased the number of pakchoi leaves and the chlorophyll content of pakchoi and lettuce and promoted photosynthesis,thereby improving the growth,development,and biomass of pakchoi.关键词
