中文摘要:根据2005年在中国科学院南皮生态农业试验站的田间试验结果,对灌溉后土壤剖面和沿畦长 方向的水盐分布进行了研究。结果表明,当灌水量相同时,灌水结束后波涌灌和连续灌0~1 00cm土层含水率在整个畦田上存在较大差别。比较灌水均匀度的结果可知,供水时间为90 min时,N=3,r=1/2,Ton=30min的处理含水率离散程度最小,灌水 均匀度最满意。从主根区含盐量的变差系数来看,连续灌明显高于波涌灌,说明微咸水的波 涌灌在畦首到畦尾的盐分分布离散程度低于连续灌。因此灌水方式的改变在不增加灌水量的 条件下改善了土壤水盐分布状况。

Abstract:Based on field experiment in Nanpi ecological experimental station of Chinese Ac ademy of Sciences, the soil water salt distribution of post irrigation both on s oil profile and along the border was studied. The results showed that, when prec ipitation rate was the same, the moisture content in 0~100cm soil layer prese nted difference between surge flow irrigation and continuous irrigation. The uni formity of water application was compared, and the best irrigation condition wa s observed when all water supply period were 90min, which was N=3, r=1 /2, and Ton=30min. Meanwhile the soil moisture content had minimal d i spersion degree, and the uniformity of water application was the most satisfacto ry. The taproot region salt content of continuous irrigation was apparently higher t han surge flow irrigation from variation coefficient, which means that the salt distribution dispersion degree of surge flow irrigation was lower than that of c ontinuous irrigation from border initial to border end. Changing irrigation meth od from continuous irrigation to surge flow irrigation can improve water salt di stribution pattern under the condition of same precipitation rate.

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.
