在平顶山叶县布置田间小区试验,采用基施和喷施相结合、单施和复施结合的方法,研究了硼锌钼及其配合施用对烟叶生长发育指标和产量产值的影响。结果表明,喷施Zn肥或硼锌钼肥配合基施对促进烟株的生长发育效果明显,Mo肥基施和Zn肥喷施处理在提高烟叶上中等比例方面效果明显,而B肥基施、硼锌钼肥混合基施或Zn肥喷施处理均有利于烟叶产量和产值提高。
Field trials were conducted in Pingdingshan Yaxian County, and the effects of Boron, Zinc, Molybdenum and their combined application on tobacco leaf growth and development index and yield and yield were studied by combination of basal application and spraying, single application and multiple application. The results showed that spraying Zn fertilizer or Boron, Zinc and Molybdenum fertilizer combined with basal fertilizer had a significant effect on promoting the growth and development of tobacco plants. Mo fertilizers and Zn fertilizers were effective in improving the medium proportion of tobacco leaves, while B fertilizers , Boron, Zinc, Molybdenum and other fertilizers or Zn fertilizers all benefit the yield and output value of tobacco.
