通过多年调查和解剖观察发现，银杏无论雌花或雄花，均由叶原基形成。长枝中部叶片的栅栏组织厚达１０７．５μｍ，净光合强度可达１３．０１ｍｇＣＯ＿２．ｄｍ￣（－２）·ｈ￣（－１），其叶腋间芽可发育成优质短枝。利用银杏具早果的潜能，采用相应的栽培技术措施，银杏密植园嫁接后第４年可开花结果，第６年产量达到９５６．２５ｋｇ·ｈｍ￣（－２）。 Through many years of investigation and anatomical observation, Ginkgo biloba, both female and male flowers, are formed by leaf primordia. The length of palisade tissue in the middle leaves of long branches was 107.5μm, and the net photosynthetic intensity was 13.01mgCO_2. dm ~ (-2) · h ~ (-1), the axillary buds can develop into high quality spur. Utilizing the potential of early development of Ginkgo biloba, corresponding cultivation techniques and measures were adopted. In the fourth year after grafting, ginkgo biloba could bloom and the yield reached 956.25 kg · hm -2 in the sixth year.
