| 摘 要： | 以辽西半干旱区2004~2008年的玉米生长参数及农业气象资料为依据,应用CROPWAT模型模拟分析了该区玉米的需水及灌水量. 结果表明,玉米生育期需水趋势总体为正态分布,年需水量在572~645mm之间,苗期、拔节期、抽雄期、灌浆期需水量分别占总需水量的11.1%、30.2%、19.8%和38.9%;玉米灌溉需水量曲线因降雨差异在不同的年份呈现不同的变化型,基本分为抛物线型、中期平台型和双峰型3种;玉米的补充灌溉主要集中于7、8、9这3个月.

| Abstract: | The corn water requirement and irrigation forecast in semi-arid area in western Liaoning were studied by using CROPWAT model, based on corn growth parameters and agro-meteorological data from 2004 to 2008. The results indicate that the trend of corn water requirement was in a normal distribution in the growth period and the annual water demand was between 572 and 645mm. The water requirements in the seedling, jointing, tasselling, and filling stages were 11.1%, 30.2%, 19.8% and 38.9% of the total water requirement, respectively. The corn irrigation requirement curves were of the parabolic type, the medium-term platform type, and double-peak type. The supplementary irrigation was fulfilled mainly in July, August and September. |
