中文摘要：

通过盆栽试验研究2种灌溉方式下土壤水分、盐分、氮素分布特征及对棉花生长的影响进行了研究。对土壤水盐的监控结果表明：土壤水分、盐分分布受灌溉方式影响显著,滴灌处理水分下渗较深,使盐分主要分布在30cm以下土壤,同时由于覆膜减少蒸发,有效的抑制了土壤返盐,在距滴头纵向30cm、水平15cm范围内根区形成脱盐区,棉花根系更容易获得生长所需水分、养分,因此棉花比浇灌处理生长旺盛。

英文摘要：

A pot experiment with 2 different irrigation method（drip irrigation and furrow irrigation）was carried out to evaluate effects on distribution of water, salt and nitrogen spatial distribution in soil and effects on cotton growth and development, The results showed that the distribution of water and salt in soil were significantly influenced by irrigation methods, water was seeped deeper in drip irrigation than in furrow irrigation, and salt was concentrated under 30cm depth, with drip irrigation under mulch, the soil water evaporation was lower than furrow irrigation, and formed a desalted zone located at 0 - 30cm depth and in 15cm width centered emitter,cotton root could absorbed more water and nutrient from root zone, the cotton plant grow better than in furrow irrigation.
