不同单行种植模式对玉米产量及经济效益影响分析

研究广西山区玉米不同单行种植模式对玉米产量及经济效益的影响,找出最佳单行种植模式,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和宜单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,不同重复间产量差异不显著,试验所用三个玉米品种产量之间的差异、品种和种植方式的互作差异和不同种植方式之间的差异都达极显著水平。单行单株种植方式平均产出投入比最低,仅为6.18;单行三株种植方式平均产出投入比最高,其值为8.61;单行双株种植方式的平均产出投入比介于这两者之间,其值为7.64。单行三株的种植方式产出投入比最高,效益最好。

Evaluation for yield and economic effects of different planting model in maize

The present study was conducted to investigate the effect of different planting models for spring maize on the yield and economic effect, to find the best planting model based on the income, and to provide scientific references for resonable and high efficient planting. The test was conducted in Hechi, Guilin, and Nanning .Three maize hybrid which were popularly planting in Guangxi were selected for this trial. The re- suits show that the anova results shown that the yield between three hybrids and the interaction of variety by planting model were significant difference, and the yield among planting models was different significantly. The average ratio of income to investment of single rows single plants was the lowest, which was only 6.18. The highest average value of that belonged to single rows triple plants. The average ratio of income to invest- ment of single rows single plant was between the lowest and highest value, which was 7.64.The single rows triple plants planting model was recommended as the best one based on this research.
