| 摘 要： | 在野外试验资料的基础上,对河套灌区荒地秋浇灌水的盐分和水分运移进行了分析。利用水盐运移平衡机理,对荒地1m深土层浸入及流失的水分及盐分进行控制。研究显示秋浇63.0%的补给水分用来淋洗盐分,荒地中1m深土壤含盐量减少了256.8g/m^2,秋浇淋洗盐分,为次年储存盐分腾出＂盐库＂。秋浇期间的水盐运移的研究,对秋浇灌溉节水具有重要意义。 |

| Abstract: | This paper carries on an analysis of the salinity and water movement of autumn irrigation of wasteland in Hetao Irrigation District based on field experimental data.Water and salinity movement balance mechanism is used to control water and salinity immersion and loss of 1 m soil layer in salt wasteland.The research shows that 63% supply water of autumn irrigation leaches salt,the salinity content reduces 256.8 g/m2 in 1 m soil layer of wasteland.A study of water and salinity movement during autumn irrigation is of great importance to watersaving in irrigation in autumn. |
| Keywords: | saline field autumn irrigation soil salinity |
