FAO Penman—Monteith及简化方法在西北适用性研究
参考作物蒸发蒸腾量 西北 参数率定 气象数据缺失
2016/12/28
为了实现气象资料缺失下参考作物蒸发蒸腾量（ET0）在西北地区的高精度预测，采用FAO 56 Penman—Monteith（P—M）公式作为对照，与气象资料缺失下P—M公式8种情况以及Pristley—Taylor（P—T）法、Makkink 法、Hargreaves—Samani（H—S）法、Irmak法对西北5省区30个辐射站的逐日气象资料进行了统计比较，并对P—T法、Makkink法、H—S...

根据国家“863”节水农业重大专项试验资料，利用FAO-56推荐的分段单值法和双值法构建了控制灌溉条件下晚稻的作物系数曲线，分析了调整灌溉或降雨后的最大作物系数值对双值法水稻作物系数计算结果的影响，并根据2004年实测资料对研究结果进行了验证。结果表明：控制灌溉条件下，晚稻分蘖期、拔节孕穗期、抽穗开花期及乳熟期的作物系数实测值分别为1.14、1.49、1.43和1.12。分段单值法得到初始生长期、...
