Spring maize yield, soil water use and water use efficiency under plastic film and straw mulches in the Loess Plateau
To compare the soil water balance, yield and water use efficiency (WUE) of spring maize under different mulching types in the Loess Plateau, a 7-year field experiment was conducted in the Changwu region of the Loess Plateau. Three treatments were used in this experiment: straw mulch (SM), plastic film mulch (PM) and conventional covering without mulch (CK). Results show that the soil water chan...
متن کاملPlastic-film mulching and urea types affect soil CO2 emissions and grain yield in spring maize on the Loess Plateau, China
A 2-year field experiment was conducted on maize (Zea mays L.) to explore effective ways to decrease soil CO2 emissions and increase grain yield. Treatments established were: (1) no mulching with urea, (2) no mulching with controlled release fertiliser (CRF), (3) transparent plastic-film mulching (PMt) with urea, (4) PMt with CRF, (5) black plastic-film mulching (PMb) with urea, and (6) PMb wit...
متن کاملSoil loss and runoff generation in rangeland, rain-fed and abandoned rain-fed agriculture land-uses under simulated rainfall
Soil erosion is a global challenge, seriously threatening soil and water resources andenvironmental qualities. One of the important factors to consider in the process of runoffgeneration and soil erosion is the physical and chemical properties of soils under differentland-uses. The aim of this study is to estimate soil erosion and runoff in rangeland, rain-fedand abandoned rain-fed agriculture ...
متن کاملSoil Respiration Response to Long-Term Freezing Saline Water Irrigation with Plastic Mulching in Coastal Saline Plain
The technology of freezing saline water irrigation (FSWI) with plastic mulching has been regarded as an effective way to reclaim the highly saline soil in coastal plains, which enabled the growth of crops in heavy saline soil that was not suitable for any crop growth before. However, after long-term treatment with FSWI, the microenvironment of the soil has been found to be affected by the growt...
متن کاملThe Effects of Plastic Film Mulching on Maize Growth and Water Use in Dry and Rainy Years in Northeast China
Plastic film mulching (PM) has been widely used to improve maize (Zea mays L.) yields and water use efficiency (WUE) in Northeast China, but the effects of PM in a changing climate characterized by highly variable precipitation are not well understood. Six site-year field experiments were conducted in the dry and rainy years to investigate the effects of PM on maize growth, grain yield, and WUE...
