水稻需水量试验是农田灌溉研究中的一项基本课题,本文根据浙江省的工作实践,对水稻需水量测试中简测法存在的无渗漏装置叶面腾发量大以及水稻需水量计算有时出现负值、非淹灌期的需水量计算、水稻生长末期停止需水量观测的适应时期等问题,都提出了讨论意见和解决的办法。 Rice water demand test is a basic issue in the study of farmland irrigation. According to the practice of Zhejiang Province, this paper analyzes the existence of leakage-free device in rice water demand test, Negative values, the calculation of water demand in non-flooded irrigation period and the adaptation period of stopping the observation of water requirement at the end of rice growth, etc., all put forward suggestions for discussion and solutions.
