【 摘 要 】
The experiment of winter wheat brackish water irrigation was carried out in Xiawa Town, Zhanhua District, Shandong Province from 2015 to 2016. Four different irrigation schemes were designed by using fresh water and brackish water of salinity of 3.0g/L. The effect of brackish water irrigation on the distribution of water-salt in saline alkali soil was studied. The results showed that the soil water content of three times irrigation could reach 12.5% ∼ 19.9%, while that of twice irrigation could only reach 10.8% ∼ 13.6% and the salt accumulation of the scheme of fresh water + fresh water + brackish water was 0.0552g/kg, which indicated that this scheme could not only supplement soil water but also accumulate less salt.
