摘　　要： 通过 16个月的周年性生产试验表明 ,在广州地区 ,超甜玉米的最适宜播种期为 2月下旬至4月上旬和 8月中下旬 ,且春播鲜穗产量高于秋播 ;在其它时期可以播种 ,但经济产量较低 ;超甜玉米的鲜穗收获期一般是吐丝后 2 6d左右 ;用抽雄到鲜穗收获期的有效积温 (≥ 10℃ )作为超甜玉米鲜穗收获期的标准要比单纯使用持续时间更为准确、科学 ,相应的有效积温为 370℃左右 . The annual productive experiment of sixteen months showed that in Guangzhou area, the best suitable sowing period of super sweet corn was between the last ten days of February and the first ten days of April, or the second and last ten days of August. The fresh ear yield of spring sowing super sweet corn was higher than that of autumn sowing super sweet corn. However, the economic yield of the super sweet sowed in the other periods was relatively low. The super sweet corn's fresh ear harvesting period was about 26 days later at threading. The effective accumulated temperature (≥10℃) between earing and harvesting used as the standard of super sweet corn's fresh ear harvesting period was more accurate and scientific than the sustainable period purely used,and its corresponding effective accumulated temperature was about 370℃.
