| 摘 要： | 30%已.乙水剂处理极显著缩短穗下部节间长度,降低了植株和果穗的重心,提高了子粒形成期和灌浆期穗下部节间单位长度干重,极显著提高穗下部节间折断时的最大载荷和径向的碾碎强度,增加了穗下各茎节的粗度,总体提高玉米茎的抗倒伏性能。同时,化控处理降低了空秆率和秃尖长,提高了行粒数和穗粒重,显著提高了产量,化控措施使玉米子粒产量与茎秆质量得到了协同改善。

| Abstract: | By spraying 30% DTA-6.ethephon solution in 6-leaf stage of maize plant,the length of internodes below ear were shortened,the center of gravity of plant became lower,dry weight of internodes below ear per centimeter was increased in kernel-forming stage and kernel-filling stage,the most load and the intensity to resist radial crushing of internodes below ear were enhanced significantly,and the diameter of internodes below ear was increased.Therefore,the capability to resist lodge of maize straw was improved ultimately by spraying 30% DTA-6.ethephon solution.In addition,because of the decrease of no-ear plant rate and length of bare ear and the increase of kernel number per row and kernel weight per ear,the yield of maize was increased significantly by spraying 30% DTA-6.ethephon solution. |
