中国农业大学农学与生物技术学院科研人员在大田条件下,以郑单958为玉米材料,在华北平原研究了乙烯利(0和180g/hm2)和氮肥水平(施氮量0、150、225和300kg/hm2)对玉米节间形态性状、化学成分和抗折断力的影响。结果表明:乙烯利显著提高基部节间最大直径、最小直径、单位节间长度干重和抗折断力,显著降低节间长度和干重。增施氮肥可以提高基部节间最大直
Researchers at the College of Agronomy and Biotechnology, China Agricultural University studied the effects of ethephon (0 and 180g / hm2) and nitrogenous fertilizer (0,150,225 and 0,150,225) on the North China Plain under field conditions with Zhengdan 958 as the maize material 300kg / hm2) on morphological traits, chemical composition and breaking resistance of corn internodes. The results showed that ethephon significantly increased the maximum diameter, the minimum diameter, the dry weight per unit internode and the breaking resistance, and significantly reduced internode length and dry weight. Increasing nitrogen fertilizer can increase the maximum straight internodes
