| 摘 要： | 本研究以粳稻辽粳5号为试材，在非称重式钢筋混凝土结构的蒸渗仪中进行水稻腾发量研究。结果表明气象因素是水稻腾发量的主要影响因素，在此基础上建立了水稻增发量与空气饱和差、日照、风速和气温之间关系的数学模型；教学模型经检验具有较高精度，可用于东北沈阳地区水稻灌区的灌溉预报。 |

| Abstract: | With nonglutinous rice Liaojing 5 as a tast material, experiments were carried out to study theevapotranspiration of rice grown in nonweighting lysimeters of reinforced concrete. The results showed that themeteological conditions were main factors affecting evapotranspiration of rice. The mathematical models for ricefield evapotranspiration were established with the factors such as saturation deficit, sunshine, wind speed andtemperature. These mathematical models have been tested with actual data and can be used to the management ofrice irrigaion in Shenyang area. |
| Keywords: | rice evapotranspiration mathematical model |
