【摘要】 用红外光谱法、核磁共振法、质谱法等方法对经三年时间人工合成的二苯脲进行的鉴定研究，以及应用情况表明，二苯脲不仅具有嘌呤类植物生长调节剂的作用，且生产成本大大低于后者，故而具有广阔的应用前景。更多还原

【Abstract】 Through our study on the determination with Infra-red Spectrum,Nuclear MagneticResonance Spectrum,Mass Spectrum et al and application of the synthetic diphenylurea for threeyears,it has been showed that it not only has a function of the purine type of plant growth regula-tor,but also has much cheaper production cost than the latter.Therefore it will have broadprospects for use.更多还原
