摘要/Abstract

摘要： 本研究通过田间试验探讨不同灌水量、不同烟气石膏用量对土壤盐分和油葵产量的影响。结果表明：烟气石膏施用量为10 t·hm-2 时,土壤脱盐效果最好,较高的灌水量处理上层土壤脱盐率较高。当灌水量为3 900 m3·hm-2、烟气石膏施用量为10 t·hm-2时,土壤耕层盐分最低,油葵出苗率和产量最高。

关键词: 油葵, 土壤盐分, 烟气石膏, 灌水量

Abstract: This field experiment studied the effects of flue gas desulphurization by-product gypsum and irrigation on soil salt content and oil sunflower yield. The results showed that the treatment with 10 t flue gas desulphurization by-product gypsum per hm2 and 3 900 m3 water per hm-2 had best desalination effect, and the desalination rate of upper layer of soil increased with increased irrigation amount. Under the conditions of application of 10 t flue gas desulphurization by-product gypsum per hm2 and 3 900 m3 per hm-2 of irrigation amount, soil salt content in the soil was the lowest, and germination rate and yield of oil sunflower were the highest．

Key words: oil sunflower, soil salt content, flue gas desulphurization by-product gypsum, irrigation amount
