| 摘 要： | 内蒙古磴口河套地区４ａ灌溉试验表明：（１）采用目前生产上的１５０００－２２５００ｍ＾３／（ｈｍ＾２．ａ）灌溉量，使土壤表层的含盐量由灌溉前的０．５ｇ／ｋｇ上升到１．０ｇ／ｋｇ以上。（２）按合理灌水定额公式计算，年灌溉量以７５００ｍ＾３／ｈｍ＾２为宜；最佳含水率下限１９．９９％；在灌水期地下水位为１．９７－３．０２ｍ，变幅１ｍ左右（３）年灌水次数应控制在８－１２次。

| Abstract: | The research on effect of drawing water from the Yellow River to irrigate the land in Dengkou was conduted in Ba League,Inner Mongolia for 4 years.The results showed that : (1) The increase of soil salinization in soil surface raised from 0.5 g/kg to over 1.0 g/ kg was because of the irrigation(15000~22500m3/(hm2·a) for 4 years.(2) The suitable amount for irrigation for each year is 7500m3/hm2 and the lowest demarcation of the best soil water rate was 19.99%.The ground water table was 1.97~3.02m,the range wits 1m of the ground water table in the period of irrigation.(3) The irrigation freciuency is 8~12 times per year. |
