高原地区机械深松对土壤水分的影响试验结果分析

Effect analysis of mechanical subsoiling on soil moisture in plateau area

为探讨高原地区机械化深松后土壤耕层水分变化特点,耕作土壤的作用和影响,分析机械深松发挥的作用效果和蓄水保墒机理,进行相关的试验研究工作。通过深松与传统的耕翻作业后土壤水分、土壤容重、土壤田间持水量等性能变化分析在高原地区深松作业对土壤性能及作物产出的影响情况,试验得出土壤含水率增加43.8%,容重下降31.3%,小麦和油菜产量增加175.5kg/hm^2和181.5kg/hm^2的结果,分析深松技术在高原地区土壤耕作中的优越和重要性。

In order to investigate the mechanical plateau after subsoiling soil moisture change characteristics,function and effect of soil tillage,analyze the effect and mechanism of water conservation of mechanical subsoiling play,work related experimental study.Analysis of soil moisture,soil bulk density,soil field capacity performance by subsoiling and conventional pouching operation after the change in the plateau area effects of subsoiling on soil properties and crop output operation situation,test results of soil moisture content increased by 43.8%,the bulk density decreased 31.3%,wheat and rapeseed yield increased 175.5 kg/hm^2 and 181.5 kg/hm^2 results,analysis of deep loose soil tillage technology in plateau region superiority and importance.
