摘要
本文首先讨论自动供水蒸散器在南京地区的观测使用情况及存在问题,然后以实测的农田蒸散值为依据,比较了几种目前常用的农田蒸散计算方法在南京地区的适用性。最后确定冬小麦、赤豆等农作物在南京地区的农田需水量及作物系数。
Discussion is first made of the application of automatic watersupply ET equipment in the area of Nanjing and the problems thusarising. Then, based on farmland ET data, comparison is made betweenseveral current calculation methods in applicability for farmland ET.Finally, water requirement and crop coefficients for winter wheat, red bean, etc.are determined.
