基于JF-1型蒸发自动测试仪的水稻作物需水量分析研究

Analysis of the rice crop requirement based on JF-1 type evaporation automatic tester

本文将江西省水利科学研究院研发的JF-1型蒸发自动测试仪首次成功应用于水稻田间蒸发蒸腾量测量.研究了水稻作物在不同气象条件下,水稻作物的日蒸发蒸腾量变化过程,为制定合理的灌溉制度,节约水资源,提高水稻作物产量有着重要的指导意义.

＂JF-1＂ type evaporation automatic tester, which is developped by Jiangxi Provincial Institute of Water Sciences, is ap- plied first successfully to measure the field evapotranspiration of the rice. The rice crop evapotranspiration course line of a day in different weather conditions is studied. Its corresponding period is also studied in order to develop the reasonable irrigation sys- tem, save water resource, improve the production of rice, control the agricultural non-point source pollution and encourage agri- cultural science experiment.
