【摘要】 为了准确估算旱作水稻作物需水量动态变化过程,制定合理的灌溉制度,试验研究采用蒸渗仪及田间试验测定作物蒸发蒸腾量方法,对旱作水稻作物需水量规律进行研究。试验结果分析:旱作水稻需水量与其它旱作作物需水量基本相同,可在水资源不足地区和井灌区规模种植。更多还原

【Abstract】 For the purpose of measuring the dynamic change of upland rice’s water demand and establishing appropriate irrigation system accurately,the research uses lysimeter as well as the method of testing the evapotranspiration of crops in field study to figure out the law of upland rice’s water demand. The result indicates that the water demand of upland rice is basically same as upland crops,which means upland rice can be planted in areas in lack of water and well-irrigated districts.更多还原
