摘要
在野外试验基础上,利用水盐平衡原理对河套灌盐荒地水盐运移规律进行研究。结果表明,盐荒地作物生育期输入盐分27.929kg/hm2,秋浇期流失盐分26.882kg/hm2,盐分积聚1.047kg/hm2,是输入盐分的3.749%。盐荒地具有一定的积盐能力。研究结果可为灌区节水灌溉的实施和土壤盐渍化的防治提供基础理论依据。
Based on the field experiment, salt water and salt transfer of uncultivated land was analyzed using water and salt balance principle in Hetao irrigation district. The results show that salt input of salt wasteland is 27. 929 kg/hm2 on the crop growth season, leaching loss of salt is 26. 882 kg/hm2 by autumn irrigation, and salt accumulation is 1. 047 kg/hm2. Salt wasteland has a certain salt accumulation ability. The results can be used in basic theoretical research for water-saving irrigation and soil salinization prevention and control in the future.
