为探讨糜子种植的生态气候适宜性,运用积分回归方法,对庆阳西峰区、天水麦积区、定西安定区及武威凉州区1985～2008年糜子产量受气候因子的影响进行了分析.结果表明:水热因子在不同的生育阶段对不同地点糜子的产量影响各不相同;在抽穗～开花期间,旬平均气温对安定、凉州、西峰、麦积糜子产量影响较大,分别为10.5 kg/(hm~2·℃)、9.0 kg/(hm~2·℃)、8.0 kg/(hm~2·℃)及5.6 kg/(hm~2·℃),在拔节期旬降水量对产量影响较大,分别为8.0 kg/(hm~2·mm)、3.0 kg/(hm~2·mm)、5.2 kg/(hm~2·mm)及5.2 kg/(hm~2·mm);甘肃各地光照基本上都能满足糜子的生长发育需要;最适宜种植区为陇东的塬区、渭河谷地及河西海拔在1 600 m以下灌溉区及敦煌盆地;最具有潜力的种植区为陇中地区及陇东的北部.

Broomcorn millet is main minor crops in Gansu. To investigate the eco-climate suitability of millet, we analyzed the influence of climate factors on the yield of broomcorn millet with the method of integral regression in Xiefeng, Maiji, Anding and Liangzhou districts from 1985～2008. The result shows that water and heat have different function on the yield of broomcorn millet in different regions at different periods in which the highest value of ten-day average temperature on the yield of broomcorn millet in Anding, Liangzhou, Xifeng and Maiji are 10.5 kg/(hm~2·℃), 9.0 kg/(hm~2·℃), 8.0 kg/(hm~2·℃) and 5.6 kg/(hm~2·℃) respectively in heading to flowering periods and the highest value of ten-day precipitation on yield of broomcorn millet are 8.0 kg/(hm~2·mm), 3.0 kg/(hm~2·mm), 5.2 kg/(hm~2·mm) and 5.2 kg/(hm~2·mm) respectively in jointing growth period. It also shows that the sunshine can satisfy the growing of broomcorn millet in Gansu. The most eco-climate suitability area is in the plateau of Eastern Gansu, the basin of the Weihe River and the irrigation area below 1 600 m above the sea level and Dunhuang Basin in Hexi corridor and the most potential eco-climate suitability area is Middle Gansu and Northeast Gansu.
