磁化水灌溉对番茄生长及生理特性的影响

通过日光温室试验，研究磁化水灌溉对番茄幼苗期和开花期生长性状与生理特性的影响，为磁化水灌溉在蔬菜生产中的应用提供依据。试验设置2个处理:磁化水灌溉、普通水灌溉（CK）。试验结果表明:与普通水灌溉相比，磁化水灌溉处理的番茄植株株高增长15%、茎粗增长8.2%；磁化水灌溉处理后的幼苗期番茄叶片SOD、POD和CAT活性分别增长22%、44.4%、18.4%，开花期番茄叶片SOD、POD、CAT活性分别增长15.8%、21.5%、48.3%；磁化水灌溉处理后的开花期番茄根系活力增长56%。磁化水灌溉能有效提升番茄生长性能、酶活性和根系活力，可为绿色、无公害蔬菜生产技术的应用提供参考。 

Effects of Magnetized Water Irrigation on Growth and Physiological Characteristics of Tomato

Effects of magnetized water irrigation on growth and physiological characteristics of tomato during seedling stage and flowering stage were studied by means of solar greenhouse experiment.Two treatments were designed，including magnetized water irrigation and ordinary water irrigation（CK）.Results showed that，compared with ordinary water irrigation，for tomato used magnetized water irrigation treatment，plant height growth was 15%，stem diameter growth was 8.2%.Magnetized water irrigation treatment had no significant effect on chlorophyll content in seedling stage and flowering stage of tomato leaves.The SOD，POD，CAT activity growth of tomato seedling stage leaves after treatment of magnetized water irrigation was 22%，44.4% and 18.4% respectively，the SOD，POD，CAT activity growth of tomato flowering stage leaves after treatment of magnetized water irrigation was 15.8%，21.5% and 48.3% respectively.Growth of root activity of tomato in flowering peniod after irrigated with magnetized water was 56%.Magnetized water irrigation could effectively improve grow performance，enzyme activity and root activity of tomato，which could provide reference for application of green，pollution-free vegetables production technology.
