摘要
玉米气候区划各地指标不同，根据玉米生长期间的生育期0、10、15、20℃积温、20～26℃适宜生长日数及生育期降水量6个生育指标，结合东阿县国家气象观测站、区域气象观测站及周围县市的气象观测资料，对山东省东阿县玉米的适宜种植区进行精细化分析。发现东阿大部分地区等都是夏玉米适宜种植区。以玉米生育期0℃积温为依据。按2200～2500℃的生育期积温要求，东阿县玉米的播种适宜时间为6月12—15日；玉米品种应选择中熟品种。东阿县玉米生育期降水量基本可以满足玉米生长需求。
Corn climate division around the indees were different. The suitable planting areas of corn in Dong＇e County of Shandong Province were analyzed, based on fertility indexes 0, 10, 15, 20℃ accumulated temperatures of corn during the growth, 20-26 ℃ days which was suitable for growing and precipita- tion in growth period, combining meteo- rological data of national meteorological observatory in Dong＇e County, regional meteorological observatory and surround- ing.counties.It was found out that most areas of Dong＇e County were suitable for planting summer corn. Taking accumu- lated temperatures during corn growing period as the basis, according to the ac- cumulated growth period requirements in 2 200-2 500℃ ,the corn appropriate planting time in Dong＇e County was June 12-15th; and corn varieties should choose maturing varieties. The precipitation during corn growth period in Dong＇e County met the corn growing demand.
