Embodiment 1

[0017] In late September in Guangzhou, by cutting off the backbone roots of potted Ginkgo biloba and moving the pots with soil, the water absorption capacity of the roots is reduced, causing physiological wilting, and then leaves, and then water once a day to keep the pot soil moist, and apply agricultural compound fertilizer 10- 20g / pot, so that the terminal buds and lateral buds that have stopped growing will start to germinate after a short (about 2 weeks) dormancy, and gradually grow new leaves. Before the severe winter comes, move the potted ginkgo with new leaves to the greenhouse for overwintering. 10M 2 One 100W incandescent lamp, the light (sunlight and light) is kept for 13-16 hours a day, and is managed as usual throughout the winter.

[0018] Implemented according to the above-mentioned technical scheme, the potted ginkgo gave birth to new leaves, and after surviving the winter, the green leaves are full of branches during the Spring Festival.

Embodiment 2--8

[0020] In the Pearl River Delta, use scissors to cut off all the leaves and terminal buds of potted ginkgo plants after late September, and carry out normal fertilization and watering. After about 15 days, new leaves will start to grow on land, and the newly grown green leaves will pass through. The plant growth substance of Table 1 is processed until the leaves are drenched, and the potted ginkgo is moved to the greenhouse as in Example 1 for overwintering in the first ten days of December.

[0021] Table 1, the plant growth regulating substance formula used in the present invention

[0022] Recipe No. Recipe

[0023] 1 Naphthalene acetic acid 100mg / l

[0024] 2 Indole butyric acid 100mg / l

[0025] 3GA 3 200mg / l

[0026] 4GA 3 200mg / l+6-benzyl adenine 20mg / l

[0027] 5GA 3 100mg / l+ naphthaleneacetic acid 100mg / l

[0028] 6GA 3 200mg / l+ kinetin 20mg / l+ naphthaleneacetic acid 100mg / l

[0029] 7 Indole butyric acid 100mg / l+6-benzyl adenine 30mg / l

Embodiment 9-15

[0031] Choose the vigorous potted ginkgo of growth, spray different plant growth substance solutions (as table 1) in the first ten days of October until the leaves are drenched, all cut off the tops of branches before spraying, to eliminate the inhibition of the top growth advantage to the side buds, 7 Cut off all the leaves after a day. Place it in the greenhouse as in Example 1 in early December to survive the winter.
