| 摘 要： | 根据疏勒河灌区新垦盐碱地土壤含盐量高，需采用水平明沟排水冲洗改良的实际，开展了不同冲洗定额的洗盐效果试验研究，提出了排盐地区系数经验公式与冲洗定额对数函数计算公式。根据表层土壤含盐量高的特点，提出了以0~30cm土层作为冲洗改良盐碱地脱盐控制层的准则，并制定了相应的洗盐定额。

| Abstract: | According to the high salinity of soil of newly reclaimed land in the Shule Rive Irrigation District, it is necessary to adopt the horizontal open--ditch to leach salt from the soil. The salt leaching effects of different irrigation ration was tested, and the empiric formula for the salt leaching ration of salinity discharge area and the logarithm function of leaching ration were proposed. According to the fact of high content of salt in the surface layer of sail, the criteria that taking 0-30cm layer at the control layer of salt leaching was set up, and the relevant salinity discharge ration was made. |
