黑龙江省早熟地区玉米宽窄行种植技术应用研究

Application Research on Planting Technique with Wide-Narrow Row for Maize in Early-maturing District of Heilongjiang Province

2008～2009年在黑龙江省克山县进行玉米宽窄行保护性耕作试验,设宽窄行与常规垄作两个处理,在不同生长阶段分别测量土壤水分、土壤容重、土壤硬度和玉米产量。结果表明,宽窄行种植与常规垄作相比,宽窄行种植土壤保水性能比常规垄作效果明显,土壤容重、硬度比常规垄作低,土壤性能得到改善,该技术减少作业环节,降低生产成本,较常规垄作增产8.3%～11.32%。

The experiment was conducted for the maize conservation tillage with wide-narrow row technique in Keshan of Heilongjiang province during 2008 - 2009. And that put to use two treatments： conventional ridge tillage and wide-narrow row planting. Then, determined the water content, soil bulk density, soil hardness and yield in dif- ferent growth stages. The results showed that the wide-narrow row planting technique had better effects in water re- tention capacity of soil, soil bulk density and soil hardness than conventional ridge tillage, so that the soil performance was improved. Moreover, the wide-narrow row planting technique cut down the cost of operations, could increase yield by 8.3% - 11.32%.
