| 摘 要： | 目的]通过一个灌溉和翻耕循环时段的土壤呼吸测定,了解灌溉和翻耕后土壤呼吸的变化规律。方法]利用闭合动态法（LI-Cor6400）在晋中盆地进行了灌溉和翻耕条件下土壤呼吸的比较测定。结果]试验结果表明,在温度相同的条件下,灌溉和耕作能明显增强土壤呼吸。灌溉地土壤呼吸的平均值大约是未灌溉地的2.3-2.4倍。耕作地土壤呼吸的平均值大约是未耕作地的1.9-2.0倍。灌溉处理的土壤呼吸值是对照的3.0倍左右。t检验表明,对照和灌溉处理之间的土壤呼吸差异均为极显著。结论]灌溉和翻耕均能明显增强土壤呼吸。

| Abstract: | Objective] The change principle of soil respiration after the irrigation and tillage was understood through its measurement in the cycle period of irrigation and tillage.Method] The soil respiration under the conditions of irrigation and tillage in Jinzhong basin was comparatively determined with closed dynamic method(LI-Cor6400).Results] The results showed that under the condition of the same temperature,the technique of irrigation and farming can significantly enhance soil respiration.The average value... |
