    摘要:

    以郑单958为供试品种,采用田间试验与实验室研究相结合的方法,研究不同施肥模式对春玉米干物质累积及转运的影响。结果表明:不同施肥模式下春玉米单位面积和单株干物质积累量高肥高氮均高于优化施氮,除2011年二者差异达显著水平外,其他生育时期差异不显著。吐丝后干物质转运量、转移效率和对子粒贡献率均以优化施氮最高,各器官表现为茎>叶>穗部营养体。完熟期产量高肥高氮比优化施氮高出2.73%(2011年)、0.49%(2012年),并且二者差异达显著水平。

    Abstract:

    Using Zhengdan 958 as material and by methods of field experiment and indoor experiment, effectsof different fertilization patterns on dry matter accumulation and transportation of spring maize were studied in thepaper. The results showed that dry matter accumulation per unit area and per plant of spring maize under high fertil-izer and high nitrogen were higher than those of optimized N fertilization, and the difference of two cultivation pat-terns reached significant level in 2011, but the were not significant in others seasons. Dry matter transportation,transportation efficiency and its contribution to grain of optimized N fertilization were high after silking stage, organswere stem > leaves > spike. The yield of high fertilizer and high nitrogen was higher than optimized N fertilizationby 2.37% in 2011 and 0.49% in 2012, and the difference of two cultivation patterns reached significant level.
