摘　　要：2005～2006年以郑单958为材料,采用微肥喷施的方法进行田间试验,研究了B、Mn和Zn肥对夏玉米花丝发育和结实率的影响。结果表明,微肥处理对玉米生殖器官的发育有一定影响,促进了花丝的生长发育,减少了败育花和败育粒,提高了结实率。Field experiment was conducted, using maize hybrid Zhengdan958 as experimental variety during 2005-2006. Effects of microelement fertilizers including B, Mn and Zn on the silk growth and development and kernel setting rate of summer maize were studied by plant spring method. The result showed that the development of repro- ductive organ was affected by treatment of microelement fertilizers, the growth and development of silk was promoted and the number of aborted flower and kernel was decreased, and the kernel setting rate was increased. The physiological and chemical mechanism of reproductive organ promoted by microelement fertilizers still need further study.
