Study on Water-Saving Mechanisms of Different Localized Irrigation Techniques in Maize

In this study,an experiment in maize was conducted to determinate the soil water,plant developing dynamic,physiological characteristics and yields in the different water conditions,including the septa-irrigation,septa-spurt-irrigation,film above irrigation and cave irrigation,and the flood irrigation as contrast.The results of the experiment show that definite condition of pre-status of soil moisture,Under the condition of 70% flood irrigation water,among the kinds of Localized Irrigation techniques,the film above irrigation is the best,followed by septa-irrigation,septa-spurt-irrigation and cave irrigation.The yield under film above irrigation is 14.4% higher than that of flood irrigation,The yields of the septa-irrigation and septa-spurt-irrigation were close to flood irrigation The yield under cave irrigation is the lowest of all irrigation ways.
