BR—120是一种促进农作物细胞伸长和分裂，提高作物叶绿素含量，增强光合作用，促进作物对氮、磷、钾及微量元素的吸收利用的新型高效植物生长调节剂。为进一步验证其效果，秦皇岛市农业局土肥站采用了由云南大学生化专家人工合成的BR——120，对叶菜类蔬菜进行了喷施试验。据 BR-120 is a new and efficient plant growth regulator that promotes crop cell elongation and division, increases crop chlorophyll content, enhances photosynthesis, and promotes the uptake and utilization of nitrogen, phosphorus, potassium and trace elements in crops. In order to further verify its effectiveness, Qinhuangdao Agricultural Bureau Soil Fertility Station used BR-120, a biochemical expert from Yunnan University, and sprayed on leafy vegetables. according to
