【摘要】 以影响鲜穗产量较大的密度、尿素与复合肥施用量3个因子为自变量,进行通用旋转设计,以鲜穗产量为因变量建立数学模型,提出了皖豫交界地带鲜食糯玉米高产栽培农艺方案。分析得出两地鲜食玉米产量最佳农艺组合为:密度为6.75万株/hm2,底肥施用复合肥450kg/hm2,在大喇叭口期追施尿素300kg/hm2,最高产量将出现在12.32～13.10t/hm2。更多还原

【Abstract】 In this article,three factors affecting the output of maize: the planting density,the urea and the dosage of duplicate fertilizer as the independent variable,were experimented in the general design of revolving.The mathematical model of the maize output was established and the high-yielding cultivation technique of glutinous maize as fresh food in the intersection of Anhui and Henan province.It concluded that: the planting density was 67 500/hm2 and the duplicate fertilizer as the base was 450 kg/hm2 for 300 kg/hm2 maize as fresh food in the tuba mouth time in the two places,so the maximum production rate would be in the scope of 12.32 ～13.10 t/hm2.更多还原
