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%。
Corn width and width row tillage tillage tests were conducted in Keshan County, Heilongjiang Province from 2008 to 2009. Two treatments, width and width row and conventional ridge row, were conducted. Soil moisture, soil bulk density, soil hardness and corn yield were measured at different growth stages. The results showed that compared with conventional ridge cultivation, the water holding capacity of wide and narrow rows was significantly higher than that of conventional ridge planting. The soil bulk density and hardness were lower than those of conventional ridge and the soil properties were improved. The technology reduced the operating cycle and reduced the production cost, Ridge yield increase 8.3% ~ 11.32%.
