摘　　要：为探讨大豆大垄垄上行间覆膜的增产机制,以垦丰15、垦丰16两个大豆品种为材料,在田间进行大垄垄上行间覆膜和不覆膜处理,研究了覆膜阶段土壤水温状况及植株形态指标变化。结果表明,行间覆膜对土壤的增温作用在大豆生育前期内呈"U"型变化,在增加耕层含水量、改善根系生长环境方面起到重要作用,覆膜大豆产量明显高于对照。In order to investigate the mechanism of applying plastic cover within a wide ridge in increasing soybean yield, two soybean varieties： Kenfeng15 and Kenfeng16 were used in a two-year field experiment. The results showed that in the early growth stages, plastic covering within a wide ridge not only increased soil temperature with the ＂U＂ variation, but also increased A layer＇s soil moisture and created a favorable environment for soybean root growth Yields of both soybean varieties were increased significantly by applying a plastic cover within a wide ridge compared with the check plots.
