深松促进春玉米干物质和磷素的积累与转运

为研究深松对春玉米干物质和磷素积累与转运的影响。以郑单958和先玉335为供试品种,设旋耕（R）、深松＋旋耕（S＋R）2个处理,通过连续2年的田间定位试验。结果表明,S＋R处理显著（P〈0.05）提高2个品种春玉米的产量、吐丝期干物质和磷积累量、干物质和磷转运量,尤以郑单958表现明显;磷收获指数、磷吸收效率、磷肥偏生产力均表现为S＋R处理高于R处理,其中郑单958磷收获指数、磷吸收效率处理间差异均达到显著水平（P〈0.05）,而先玉335处理间差异不显著。深松能促进春玉米干物质和磷的积累、转运,提高磷的收获指数、吸收效率和偏生产力,但不同玉米品种间存在显著的差异,郑单958产量和磷效率对深松...

Summary:为研究深松对春玉米干物质和磷素积累与转运的影响。以郑单958和先玉335为供试品种,设旋耕（R）、深松＋旋耕（S＋R）2个处理,通过连续2年的田间定位试验。结果表明,S＋R处理显著（P〈0.05）提高2个品种春玉米的产量、吐丝期干物质和磷积累量、干物质和磷转运量,尤以郑单958表现明显;磷收获指数、磷吸收效率、磷肥偏生产力均表现为S＋R处理高于R处理,其中郑单958磷收获指数、磷吸收效率处理间差异均达到显著水平（P〈0.05）,而先玉335处理间差异不显著。深松能促进春玉米干物质和磷的积累、转运,提高磷的收获指数、吸收效率和偏生产力,但不同玉米品种间存在显著的差异,郑单958产量和磷效率对深松更为敏感。该文可为春玉米高产高效栽培提供依据。

Years of small power mechanical shallow rotary tillage often lead to shallow top soil layer and thick plough pan in the root layer. In addition, available phosphorus （P） content is relatively low in calcareous soil, so the nutrient use efficiency of P is low, limiting the maize yield. Subsoiling is an effective mean to solve those issues. In this study, the effects of subsoiling on dry matter, P accumulation and transportation of spring maize were studied. Zhengdan 958 and Xianyu 335 were used as materials and 2 treatments （rotary tillage vs. subsoiling plus rotary tillage） were set through field experiments consecutively for 2 years. The results showed that under the sub
