中文摘要:夏玉米/冬小麦轮作期间,设置3种灌水处理:地下水灌溉,灌水定额52.5mm;再生水灌溉,灌水定额52.5mm;再生水灌溉,灌水定额105mm,研究了田间0~450cm包气带土壤中主要盐分离子的迁移规律。结果表明:盐分离子质量比和电导率在土壤中从大到小依次为:380~450cm壤土土层、0~120cm壤土土层、120~380cm砂土土层;再生水中可溶性K+和Cl-表现出较强迁移能力,影响深度450cm,K+在0~450cm土层变化,但Cl-主要在0~250cm土层变化;可溶性Ca2+和电导率的影响深度为380cm,但主要在0~120cm土层变化;380~450cm壤土土层对盐分离子的迁移起到了阻滞作用,大幅降低了地下水受到污染的风险。建议利用灌水定额为52.5mm的再生水灌溉,夏玉米灌水1次,冬小麦灌水4次或更少。

Abstract:Over the course of one summer maize and winter wheat rotation cycle, three irrigation treatments (ground water with a quota of 52.5mm; reclaimed water with a quota of 52.5mm; reclaimed water with a quota of 105mm) were set up, and in each treatment, the soluble K+, Ca2+, Cl- and the electric conductivity (EC) leaching and migration in 0~450cm soil were studied. The results showed that the soil salinity content and EC value were in the following descending order: 380~450cm loam soil layer, 0~120cm loam soil layer, and 120~380cm sandy soil layer. Soluble K+ and Cl- in reclaimed water had a strong leaching and migration ability, and reached the 450cm depth, and the influences of reclaimed water irrigation on soluble K+ and Cl- changes were mainly in 0~450cm soil layer and 0~250cm soil layer, respectively. Soluble Ca2+ and EC reached the 380cm depth, but the influences of reclaimed water irrigation on soluble Ca2+ and EC changes were mainly in 0~120cm soil layer. The 380~450cm soil layer played a role as a block layer for soil salinity leaching, and decreased the pollution risk of soil salinity ion to groundwater. It suggested that irrigation with reclaimed water with a quota of 52.5mm, while irrigation 1 time and 4 times or less during the summer maize and winter wheat growing seasons, respectively.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
