摘要
选取代表甘肃省不同气候生态区的成县(温热湿润区)、礼县(温暖半湿润区)、平凉(温和半湿润区)、武威(温和干旱区)4个点资料,运用积分回归方法分析了玉米生育期光、热、水气候生态因子对玉米气候产量的影响,并建立了不同气候生态区气候产量静态模型;以筛选后的关键气象因子为主要区划指标,对甘肃省玉米进行气候生态适生区划,并对玉米高产优质气候生态资源合理开发利用的途径进行了探讨。
Chosen four station, which standed for the different ecoclimate area in Gansu, Cheng(the warm hot moist district), Li(the warm half district), Pingliang(the gentle half moist district), Wuwei(the gentle arid district), and applied the way of integral regression to analysis the ecological factor effect on the corn output of weather during growth, including sunshine?temperature?water. Using the key meteorological factors as division indexes, the most suitable planting zone and the suitable planting zone of corn in Gansu were divided rationally, meanwhile, and offered the meteorological basis to base construction of corn.
