摘    要:以先玉335为试验材料,在大田条件下设置4种耕作方式处理,研究耕作方式对春玉米产量及各器官磷含量、磷素吸收、积累和利用的影响。结果表明,苗带紧、行间松型耕作方式下玉米的产量最高,苗带松、行间紧型耕作方式次之,苗带、行间全松型耕作方式产量最低。开花期,苗带紧、行间松型耕作方式下根系磷含量和磷积累量均最高;成熟期,苗带紧、行间松型耕作方式下根系、茎秆和子粒的磷含量及磷积累量显著高于其他处理。苗带紧、行间松型耕作方式下玉米的磷素吸收效率、磷素偏生产力、磷素贡献率和磷素转移效率显著高于其他处理,磷素干物质生产效率和磷素子粒生产效率显著低于苗带、行间全松和苗带、行间全紧处理。相关分析表明,粒重与磷素子粒生产效率、磷素吸收效率、整株干物重、磷素收获指数显著正相关,与磷素偏生产力、磷贡献率极显著正相关。

关 键 词:玉米  耕作方式  磷素积累  产量

Abstract:Xianyu 335 were chosen as the experiment material. A field experiment was conducted to study the effects of four tillage methods on the phosphorus content, phosphorus absorption, accumulation and utilization of spring maize. The result showed that the maize yield of compact seedbed and loose ridge furrow alternative tillage was the highest among these 4 tillage methods. Phosphorus content and phosphorus accumulation of root in compact seedbed and loose ridge furrow alternative tillage were the highest at flowering stage. Phosphorus content and phosphorus accumulation of root, stem and grains in compact seedbed and loose ridge furrow alternative tillage significantly higher than other tillages at maturing stage. Phosphorus uptake efficiency, phosphorus partial productivity, phosphorus contribution rate andphosphorus transportation efficiency of maize in compact seedbed and loose ridge furrow alternative tillage were significantly higher than other tillages. The correlation analysis showed that grain weight was significantly and positively correlated tophosphorus grain production efficiency, phosphorus uptake efficiency, plant dry matter weight and phosphorus harvest index, and highly significantly and positively correlated tophosphorus partial productivity andphosphorus contribution rate.
Keywords:Maize  Tillage method  Phosphorus accumulation  Yield
