| 摘 要： | 通过测坑试验研究,应用水稻6个生育阶段不同灌水处理下的蒸发蒸腾量和产量的试验资料,用Jensen模型、Blank模型、Singh模型和Stewart模型分别对寒地黑土区水稻的水分生产函数进行了拟合,并对得出的模型求解结果进行了比较分析与检验。结果表明,Jensen模型适合寒地黑土区水稻的水分生产函数模型计算,得出了敏感指数在生育期内的变化规律。为黑龙江省稻灌区调亏灌溉条件下的灌溉制度优化提供基础依据。

| Abstract: | Through the means of pit-grown test,according six growth stages of rice to set up different irrigation treatments and depended on evapotranspiration and the yield of test data,used Jensen model,Blank model,Singh model and Stewart model to calculate the rice-water production functions in black soil of the cold regions and the results obtained were compared with the analysis.The results show that Jensen model is suitable for the rice-water production functions in Black Soil of cold regions and obtained the variation of sensitive index in the growth period.This result provides a scientific basis for optimum irrigation system of rice under the regulated deficit irrigation in rice irrigation district of Heilongjiang Province. |
