| 摘 要： | 研究广西山区玉米不同双行种植模式对玉米产量及经济效益的影响，找出最佳双行种植模式，为广西山区玉米合理和高效种植提供科学依据。以广西玉米主推品种正大999、正大619和玉美头105为供试材料，于2011年在广西3个有代表性的玉米产区进行玉米不同双行种植模式试验。试验结果表明所用三个玉米品种产量之间的差异不显著，但不同地点间产量差异显著，品种和种植方式的互作差异不显著，但不同种植方式之间差异极显著。双行双株种植方式产出投入比最低，仅为5．84；双行三株种植方式产出投入比最高。其值为6．23；双行单株种植方式的产出投入比介于这两者之间，其值为6．06，双行三株的种植方式产出投入比最高，效益最好。

| Abstract: | To study the impact of different double-row planting models for spring maize on the yield and economic benefit, to find the best planting model and to provide scientific references for reasonable and high efficient planting in Guangxi mountain area. To take main varieties popularly planting in Guangxi such as Zhengda999, Zhengda619 and Yumeitoul05 as tested materials, the experiment was conducted in Hechi, Guilin, and Nanning.The results show that the yield difference between three varieties and the interaction of variety ＆ planting model were not significant, but the yield between different locations was significant but the interactions of variety ＆ planting model were extra significant. The ratio of income to investment of double-row ＆ double plants was the lowest, only 5.84. The highest ratio belonged to double-row ＆ triple plants and was 6.23. The ratio of income to investment of double-row ＆ single plant was between the lowest and highest ratio, which was 6.06. The double-row ＆ triple plants planting model was recommended as the best one based with best economic benefit. |
