 Exploring optimal soil mulching for the wheat-maize cropping system in sub-humid drought-prone regions in ChinaYajin Hu, Penghui Ma, Binbin Zhang, Robert L. Hill, Shufang Wu, Dong, Qin’ge and Guangjie Chen Agricultural Water Management, 2019, vol. 219, issue C, 59-71 Abstract: The application of soil mulching is widely used to improve crop productivity within semi-arid regions of China, but little is known when using a crop rotation system in the sub-humid drought-prone regions as to whether the mulching practice may perform as well as in semi-arid regions. A field study was conducted during two consecutive cycles of a wheat (Triticum aestivum L.) - maize (Zea mays L.) cropping system within the Yangling District of Northwest China to evaluate the effects of different mulch cultivation practices on soil water contents and soil temperatures (EM50 probes), crop yields, and water use efficiency (WUE). Four treatments were evaluated: (1) a flat plot without mulch control treatment (CK), (2) a flat plot with straw mulch (SM), (3) a flat plot with plastic film mulch (PM), and (4) a ridge-furrow planting with film mulch over the ridge and wheat straw mulch over the furrow (PSM).
