摘要
在彭曼法推算水稻需水量的基础上,结合武穴市的气象、地形条件,用“浅、蓄、湿、晒”灌溉技术计算一定设计保证率的水稻灌溉定额.将该法用于武穴市魏高邑项目区土地整理中,有很高的实用价值,计算精度也较高.
On the foundation of Perman＇s method for reckoning rice water requirement, combines climate and terrain condition of Wuxue city and use ＂shallow flooding, water storage, moistening, drying＂ technique to calculate rice＇s irrigation under irrigation planning guaranteed ratio.
