• 无论隔绝蒸发还是在自然蒸发条件下,短期内土壤吸力土层深度增加下降升高的趋势,同一深度土层吸力时间的推移而升高;

    Regardless of preventing evaporation or not, soil water suction decreased firstly and then increased with the increase of soil depth, and soil water suction at the same depth increased with time.

  • 灌溉技术核心天空要蒸发充分利用自然降土壤分,满足作物需要

    The kernels of the rain conservation irrigation technology are increasing effective rain - fall, decreasing evaporation and sufficiently using soil water to satisfy the crops demands.

  • 研究结果表明高聚物不仅提高土壤增加土壤对植物的有效性,而且能抑制土壤水蒸发

    The result shows that the high polymers VAM and PHM can not only enhance the water retention ability and the available water content, but also prevent the evaporation from the surface soil.

  • 农田平衡中,测定要素有农田蒸腾蒸发量、地下毛细上升土壤水渗漏量。

    Of all components of water balance in farmlands, evapotranspiration, capillary rise from a water table and deep percolation are difficult to determine.

  • 土壤收支正平衡,入渗雨量的大部分(>80%)为强烈蒸发蒸腾所消耗

    In rainy year, soil water storage increased, but most infiltrated rainfall (more than 80%) was consumed by intensive evapotranspiration.
