Abstract
Three tillage treatments,such as subsoiling at 30 cm,subsoiling at 40 cm and no-tillage,were designed to investigate the effects on summer maize growth,physiological characteristics,yield and water use efficiency(WUE)with XY 335 as the experimental material.Results showed that subsoiling significantly promoted plant height,leaf area index and ear height while subsoiling reduced the stem diameter compared to no-tillage.Subsoiling also improved soil water content in 0~60cm and deeper layers below60 cm,especially subsoiling at 40 cm.Subsoiling was beneficial to the opening of stomata,the increase of chlorophyll content and the decline of sucrose concentration and canopy temperature.Compared to no-tillage,subsoiling increased yield,water use and WUE by 18.3%,7.7%and 9.6%,respectively.Subsoiling,especially subsoiling at 40 cm,could significantly improve the physiological characteristics of maize and mitigate the drought stress during the growing season of summer maize.
