| 摘 要： | 滴灌条件下的水盐运移特性是寻求开发利用盐碱地和次生盐碱化防治的基础,国内外学者对此进行大量研究。通过对试验区滴灌灌水后土壤水盐运移特征分析研究表明:土壤含盐量表现为随水移动,各土层含盐量都有所不同垂直方向盐分的积累,在0~80 cm土层逐渐增加,80~120 cm土层盐分积累受滴灌灌水影响较小;水平方向背行中央土层处盐分积累最多,滴头处盐分积累最少。土壤电导与土壤总盐含量呈正相关,土壤pH与土壤含水量有关,土壤含水量高的地方,土壤pH也大。 |

| Abstract: | The results showed that with the retardation of postemergences,the salt content in different soil layers were increased to different degree;the accumulation of salt in vertical direction was gradually increasely at the depth of 0~80 cm,butthat at the depth of80~120 cm was little increased;the accumulation of salt in horizontal direction at the center of open ground was greater than that of other position and the that under the drop point is the least. |
