【Abstract】 The plant height and the number of leaves of one-year-old ginkgo (Ginkgo bibola L) seedlings hadbeen significantly increased as treated with 80 mg/kg "802", and treated with 50 mg/kg "Aiduoshou" and 70 mg/kg "Yemianbao", the plant height and the mumber of leaves had been notable incraeased, respectively.
