摘  要:
针对黄淮海平原地区淡水资源匮乏的问题,以当地浅层地下水配置不同矿化度的微咸水进行盐分胁迫实验,对冬小麦主根区土壤含盐量、冬小麦产量以及叶面积指数对盐分胁迫的响应进行了分析。结果表明,在不同的生育期降水量条件下,冬小麦对盐分胁迫有着不同的响应。为获得满意产量,在当地的土壤条件下,生育期一般年和湿润年可以采用的最高矿化度为3 g/L,而在生育期偏旱年,如果不采取其他措施的条件下,可以采用的最高矿化度为2 g/L,该结果为合理开发利用当地的地下咸水资源提供了一定的依据。

摘  要:
To solve the shortage of freshwater resources in Huanghuaihai plain,salt stress experiments were carried out with different mineralization degrees slight saline water,the response of soil salt content of active rooting zone,yield and leaf area indexes to salt stress were analyzed.It showed that winter wheat has different responses under different rainfalls in growth duration.In order to obtain satisfactory yields,the highest degree of mineralization was 3g/L in wet years and general years under local soil conditions,while in the drought years,the highest degree of mineralization could be used was 2g/L without taking other measures.The results provided some basis for the rational development and use of local underground saline water resources.
