摘 要:通过对干旱内陆河灌区田间土壤水、盐及土壤肥力动态监测试验分析,结果表明:在干旱内陆河灌区,棉花全生育期里,灌水前后土壤盐分变化明显,积盐脱盐交替频繁。土壤的肥力对土壤盐分的影响很大。通过对干旱内陆河灌区土壤水盐运移规律的研究和分析,可以为合理灌溉和防止土壤次生盐渍化提供科学依据,为当地农业生产作出指导,具有一定的现实意义。According to dynamic analysis of monitoring experiment for soil water, soil salt and ground water transport in soil in arid inland river irrigation region. It is concluded that: In arid inland river irrigation area, irrigation front and back soil salinity change is obvious; product salt and desalination superseded frequently in cotton entire child-bearing period. The impact of the soil fertility over soll salinity is very big. By the fact that water salt transports research and analysis changing law to arid continental river irrigation area soil, can provides scientific basis for rationally irrigating and guarding against soil secondary salinization, the agriculture produces for locality making direction, have certain practical or immediate significance.
