中文摘要：
通过盐渍土壤盆栽玉米试验，对不同灌水处理下玉米的生长发育及土壤水分和热量的变化情况进行了对比研究。结果表明保持适宜的土壤含水量可以起到调控地温，维持良好土壤根际环境的作用；灌水方法和灌水定额对盐渍土壤中玉米的生长发育具有决定性影响；交替灌溉能促进玉米根系的发育和分支，优化根冠比例，提高作物水分利用率；交替灌溉能够促进玉米对水分和养分的吸收，是一种在盐渍土壤中切实可行的节水灌溉方法。
英文摘要：
Using the method of cultivating maize in saline soil in pots, growth of maize and change of water, temperature in saline soil were studied under different irrigation treatments. The results showed that appropriate soil water content could regulate soil temper ature and maintain good soil rhizosphere environment, irrigation method and irrigation requirement had a decisive influence on the growth of maize in saline soil, alternative irrigation could promote the growth and branch of maize roots, optimize the root cap ratio, increase crop water use efficiency, alternative irrigation could promote water and nutrients absorbed by maize and was a practical wa ter-saving irrigation method in saline soil.
