绿洲防护林不同滴灌水量下土壤水盐运移初探/The Effects of Drip Irrigation with Different Quota on the Soil Water & Salt Conditions in Oasis Shelter Forest[J]

open access: yes, 2013
为了探明滴灌滴头流量一致条件下,不同灌水量处理对绿洲防护林地土壤水盐随时间分布的影响,采用30L·株-1·次-1(处理I)、40 L·株-1·次-1(处理Ⅱ)、50 L·株-1·次-1(处理Ⅲ)不同处理对比试验,在塔里木河下游喀拉米吉镇绿洲人工栽培的防护林地进行了野外滴灌监测.结果表明:①处理Ⅰ、Ⅱ、Ⅲ的剖面平均含水量分别达6.68%、8.99%、9.92%,土壤湿润锋运移的水平距离分别为58、62、74 cm,垂直深度分别为40、50、67 cm,表明灌水量决定土壤含水量的高低 ...

Study on the dynamic changes of salt of the new-cultivated soil in Agriculture exploitation area of Kelamay

open access: yes, 2004
土地盐碱化是世界性的一个重大问题。克拉玛依农业开发区是新疆引额济克工程的配套建设项目,是该工程沿线中最大的农业开发区。由于当地的气候特点、土壤及水文地质条件,土壤的次生盐渍化威胁严重。灌水洗盐和改良土壤是开发利用的关键。本文采用田间实验、室内模拟、大面积调查,对开发区不同改良措施、不同灌溉情况下克拉玛依新垦土地盐分的动态变化进行了研究。运用溶质的对流弥散方程计算出了不同作物、不同土壤质地下的洗盐定额。利用EM38大地电导仪测量了近三万亩已耕作土地的电导值,分析了开发后土壤盐分变化。通过研究 ...
