| 摘 要： | 以田间试验资料为基础，研究了苏南地区稻田小麦套种玉米生产力和技术优化组合问题。结果表明，该地区稻田种植麦套玉米可获得７０００－７５００ｋｇ／ｈｍ＾２以上的产量，技术优化后单产可达９０００－１０５００ｋｇ／ｈｍ＾２。统计分析表明，播期、密度施肥总量三项技术因子对产量影响较大，密度和产运筹对净收入影响较大，肥料运筹麦幅比和播期对利润影响最大。

| Abstract: | Potential productivity and optimization of cultivating techniques for spring corn relayed with wheat were studied based on the field experiment data. The results showed that a spring corn yield of 7 000 7 500 kg/hm 2 might be obtained in paddy field, and a yield as high as 9 000 10 500 kg/hm 2 might be obtained if cultured with the optimized techniques. Statistic analysis indicated that sowing date (SD), plant density (PD), total fertilizer(TF) had strong effects on the yield, PD and fertilizer planning(FP) on the net income, and FP, ratio of wheat belt(RWB) and SD on the profit. |
