In Shan Ye, the material selection of potted Ginkgo biloba is generally seedling raising or stump digging. The former takes shape slowly, while the latter destroys natural vegetation. At present, the commonly used methods are pile cutting and pile cutting grafting. The stump cutting method is to select the stout stump of Ginkgo biloba, which is about 50 ~ 60 cm long and 20 cm thick with some small branches on it. You can cut the branches short, leaving only a few branches and leaves, and bury them in the plain sand to form healing tissue in a cold room. Before treatment, it is best to soak 65433 in 40 ~ 50 mg/L indolebutyric acid solution. Rooting began after 2 ~ 3 months, and after survival, it was moved into culture soil, which consisted of 1 part plain sand, 2 parts humus soil and 3 parts garden soil. After shading 1 ~ 2 weeks, it will be transferred to normal management. After 2 ~ 3 years of plastic packaging, multi-leaf potted ginkgo can be formed. The stump grafting method is to select stump with a diameter of 20-30cm and a length of 30-40cm. Before grafting, 3-4 seedlings of Ginkgo biloba should be 2-3 years old with a diameter of 65,438+0-2 cm. Ginkgo biloba must survive before grafting. Then, according to the root grafting method, the bark of the stump was stripped in four directions with a bamboo stick, and the scion was cut into horse ears with the section length of 1 ~ 1.2 cm. Then insert the scion into the cortex of the stump, wrap it tightly with plastic film, and keep a certain temperature and humidity in the plastic sleeve. The suitable grafting time is 10 day before and after Tomb-Sweeping Day, and 1 ~ 2 months later, it germinates and survives. In the early stage of survival, it is necessary to strengthen the temperature and humidity management, keep the room temperature at 15 ~ 20℃, and often spray water around the plants for humidification.
