摘要
[目的]分析春玉米、春马铃薯种植的农业气候资源.[方法]根据玉米、马铃薯对气象条件的需求,利用彭州市气象观测和土壤湿度资料,采用统计学方法,分析了春玉米、春马铃薯种植的农业气候资源以及彭州市春玉米与春马铃薯套种的农业气候资源优势.[结果]春玉米、春马铃薯的适宜播种期分别为3月下旬～4月上旬、2月上旬～3月上旬.春玉米和春马铃薯生育期间热量资源丰富,土壤水分充足,降水量及总体分布适宜,日照尚够,能满足各生育期的需要,总体配置协调,适宜两者种植.[结论]采用春玉米与春马铃薯套作,可以最大限度地利用土地、时间、空间,提高光热利用率、改善农田环境、减轻病虫害、增加单位面积的产出,从而实现经济效益最大化.
Abstract
[Objective] The aim was to analyze agricultural climate resources for spring maize and spring potato planting.[Method] According to the demands of maize and potato on meteorological conditions,using meteorology observation and soil humidity data in Pengzhou City,adopting statistics method,agricultural climate resource for spring maize,spring potato planting and advantages of interplanting were analyzed.[Result]The results showed that the suitable sowing periods for spring maize and spring potato are late March-early April,early Februaryearly March.The heat resources are abundant,soil moisture is adequate,the overall distribution of precipitation is appropriate,and sunshine is enough in growth period of spring maize and spring potato.[Conclusion] Spring maize and spring potato intercropping can utilize land,time,space in the largest extent,improve the farmland environment,reduce plant diseases and insect pest,increase output per unit area,thus to achieve the maximization of economic benefits.
