摘要: 旨在研究植物生长调节剂玉黄金在拔节期叶面喷施对不同玉米品种生长发育的影响。以‘M753’、‘中试6322’、‘kws3564’3 个玉米品种为材料,在拔节期(8 叶期)叶面喷施植物生长调节剂玉黄金,调查株高及出籽率等9 个指标。‘M753’在密度为135000 株/hm2时出籽率显著大于其他2 个品种,而且株高、穗位高、叶长及叶宽显著降低。玉米在拔节期叶面喷施玉黄金可显著降低株高、穗位高、叶长及叶宽,优化株型,提高出籽率。

Abstract: The objective is to study the effects of plant growth regulator Yu- huang- jin on growth and development of different maize varieties at jointing stage. Three varieties‘M753’,‘pilot 6322’and ‘kws3564’were used as materials, by foliar spraying plant growth regulator Yu-huang-jin at jointing stage (8 leaves stage), 9 indexes were investigated including plant height and the seed rate and so on. At the density of 135000 plants/hm2, the seed rate of‘M753’was significantly higher than those of the other varieties. At the same time, plant height, ear height, leaf length and leaf width decreased significantly. Taken together, foliar spraying plant growth regulator Yu-huang-jin at jointing stage could reduce plant height, ear height, leaf length and leaf width obviously, and optimize plant type and increase the seed rate.
