面临现时代和未来可利用的水资源愈来愈贫乏的状况 ,国内外不少的机构和研究者都在不懈地探讨如何节约水资源、提高水的利用率 ,即减少灌溉水分无效蒸腾蒸发量、提高作物产量和经济效益 ,日本的“低正压地中连续灌溉法”就是其中比较先进的一例。所谓的低正压地中连续灌溉法 ,
Faced with the increasingly poorer water resources available now and in the future, many organizations and researchers at home and abroad are relentlessly exploring ways to conserve water resources and increase water use efficiency, namely, to reduce ineffective evapotranspiration of irrigation water , Improve crop yield and economic efficiency, Japan’s “low pressure in the continuous irrigation method” is one of the more advanced one. The so-called low pressure in the continuous irrigation method,
