摘　　要：【目的】为更好地在玉林市推广种植冬种甜玉米,充分利用冬闲田,提高复种指数,增加农民收入。【方法】2008～2009年在玉林市进行冬种甜玉米不同播期和栽培方式的比较试验,收获后进行考种,并进行数据分析。【结果】不同播期和栽培方式对冬种甜玉米穗长、株高、单苞重及产量均有不同程度的影响,播期以早播或迟播较有利于其生长和提高产量;栽培方式以地膜覆盖栽培产量最高。【结论】在玉林市冬种甜玉米华珍76的适宜播期为12月5日,适宜栽培方式为地膜覆盖栽培。[Objective]In order to make use of winter fallow fields, improve multiple cropping index and enhance the income of farmers, the cultivation of sweet corn was attempted to be extended in winter. [Method]The sweet corn variety Huazhen 76 was sown at six different dates in winter using four cultivating patterns in Yulin from 2008-2009. Comparative analysis of agronomic and yield traits was performed. [Result]Different sowing dates and cultivating patterns variously affected the ear length, plant height, single ear weight and yield of maize. Both early and late sowing dates were found to be advantageous in terms of the growth and yield. The highest yield of Huazhen 76 was obtained when it was planted using plastic film mulching cultivation method. [Conclusion]The fallow fields may be utilized by planting corn variety Huazhen 76 on 5th December using plastic film mulching cultivation method in Yulin City.
