Effects of Different Mulches of Buried Drip Irrigation on Soil Water Variation
In order to understand the influence of different coverage of buried drip irrigation on the soil water change rule,experi-mental areas of buried drip irrigation under different coverage conditions were set up during the growth of corn,and soil water frac-tion data were collected to analyze the soil water change under different coverage conditions.The results showed that different mulching under subsurface drip irrigation had significant effects on soil water variation.Under the condition of flood irrigation,soil water content under non-mulching irrigation was higher than that under mulching irrigation,and this phenomenon was most signifi-cant at the jointing stage of maize,which gradually weakened to disappear with the advancement of maize growth.Under shallow and deep drip irrigation conditions,the soil water content of non-mulching irrigation was higher than that of mulching irrigation.The flood irrigation system of the experiment is suitable,and the shallow and deep drip irrigation irrigation systems need to be further op-timized.
