| 摘 要： | 通过改变玉米垄向栽培，明确不同光照强度对玉米高光效生产差异性。此试验通过设计东西垄、南北垄、东南西北垄、西南东北垄四种垄向（4种不同光照强度），研究不同光照强度对玉米垄体温度、垄沟温度、土壤相对含水量及产量的效应。结果表明：4种光照强度对垄体温度总体表现南北垄>东西垄>东南西北>西南东北，垄沟温度总体表现东南西北>南北垄>东西垄>西南东北，土壤相对含水量总体表现南北垄>东南西北>东西垄>西南东北，产量总体表现西南东北>南北垄>东西垄>东南西北，但所有测试指标处理间均未达差异显著水平，说明垄向栽培方式不是影响土壤物理指标和产量的重要因素。因此，结合试验数据和生产实践，黑龙江省采取南北垄和东西垄更有利于田间作业，降低作业成本。

| Abstract: | The four different direction ridges which indicate different illumination intensity.East-west ridge,south-north ridge,south-east ridge and south-west ridge were designed in this experiment.Effect of different illumination intensity on ridge temperature,furrow temperature,water content of soil and yields of maize were analyzed.Effect of different illumination intensities on ridge temperature showed that south-north ridge > east-west ridge > south-east ridge > south-west ridge.Effect of different illumination... |
