针对山西旱作玉米田,采用行间深松免耕作业,研究了玉米深松免耕种植土壤容重、土壤水分等的量化指标及其对玉米产量的影响。试验结果表明,采用玉米深松免耕种植模式可以改善土壤结构,提高土壤蓄水能力,促进玉米生长与产量提高。0~60cm土壤容重深松免耕比旋耕平作分别降低了5.45%(2008年)、3.47%(2009年);生育期平均蓄水量深松免耕比旋耕平作分别增多5.43%(2008年)、5.88%(2009年);玉米穗数、穗粒数和百粒重优于对照;先玉335产量深松免耕比旋耕平作分别提高6.15%(2008年)、8.77%(2009年),富友9号产量深松免耕比旋耕平作提高7.05%(2009年)。试验结果表明,深松免耕种植是适合旱作地区推广的一种保护性耕作模式。 Aiming at the dry farmland of Shanxi, this paper studied the quantitative indexes of soil bulk density, soil water content and other effects on the yield of maize under deep-plowing and no-tillage maize cultivation. The results showed that using deep-plowing and no-tillage corn planting mode can improve soil structure, increase soil water storage capacity and promote corn growth and yield. The soil bulk density of 0 ~ 60cm soil subsided was lower than that of rotary cultivation by 5.55% (2008) and 3.47% (2009) respectively. The average water storage during growing period increased by 5.43% Year) and 5.98% (2009) respectively. The number of ears per ear, the number of grains per ear and the weight of one hundred grains were better than those of the control. The yield of deep-root no-till of Xian-yu 335 was increased by 6.15% (2008) and 8.77% Year), Fuyou 9 yield deep pine no-tillage than rotary flattened increase 7.05% (2009). The results showed that the deep-plowing and no-tillage cultivation is a conservation tillage mode suitable for popularization in dry farming areas.
