| 摘 要： | 通过田间小区试验,分析3个不同滴灌棉田春灌灌水量1350、1800和2250 m3/hm2对盐分变化的影响。试验表明:在相同灌水量下,宽行、窄行和膜间3个不同行距的脱盐效果,宽行最好;3个灌水量下,1800 m3/hm2的灌水量对盐分淋洗效果较好。此结果可为当地春灌提供指导,对制定灌溉制度有一定的借鉴作用。

| Abstract: | Through the field experiment,the paper analyzed the influence of three different drip irrigations of 1350,1800 and 2250 m3/hm2 in spring on soil salinity variation.The experiment showed that in the same amount of irrigation,the effect of desalination for wide row is the best in the three different rows of wide,narrow and each film.Result showed that the amount of irrigation of 1800 m3/hm2 has the best salt leaching effect and can provide a reference for spring irrigation and has certain reference for the formulation of irrigation schedule. |

| Keywords: | spring irrigation amount of irrigation desalination salt leaching variation of soil salinity cotton field |
