Problems solved by technology

In the natural state, the 1-year-old ginkgo seedlings hardly have re-drying, and the seedlings over 2 years old will not have the phenomenon of re-drying clusters until the ancient ginkgo trees of a thousand years, but in the natural state, the occurrence of ginkgo re-drying is relatively slow, less frequent

Embodiment 1

[0038] 1. Ginkgo seedling stubble transplanting preparation work

[0039] Tool preparation: pruning shears, high pruning shears, shovel.

[0040] Seedling stock selection: Select the robust seedlings with a seedling age of 3 to 5 years in the nursery as the objects for stubble transplanting and mark them.

[0041] 2. Selection of stubble and transplanting time

[0042] The stubble and transplanting of ginkgo seedlings can be carried out after defoliation, but the best stubble time is the period from the complete defoliation of ginkgo to the beginning of the Spring Festival, that is, from the beginning of December to the beginning of February of the next year. In Tai'an, Shandong, the best time for stubble leveling is December, and the time for leveling stubble in this embodiment is mid-December, and transplanted immediately after leveling stubble.

[0043] 3. Seedling stubble

[0044] The seedlings marked in the nursery are stubbled, and the trunk is cut off at a distance o...

Abstract

The invention discloses a method for promoting gingko compound stem generation. The method includes the following steps of conducting stumping treatment on gingko stock at the position which is 5-8 cmabove the ground, instantly conducting transplanting after stumping, cutting off main roots of the gingko stock to reserve the main roots by the length of 15-20 cm, well preserving fibrous roots, andconducting planting in time. By means of the method, the compound stem generation rate of the gingko stock and the number of compound stem generation times of each plant can be remarkably improved, and the requirements for the rejuvenating and seedling breeding of gingko, the operating of a leaf picking garden and the improving of adaptability are met.

Description

technical field [0001] The invention relates to the technical field of tree growth and reproduction, in particular to a method for promoting the occurrence of ginkgo re-drying. Background technique [0002] Ginkgo biloba (Ginkgo biloba L.) is the oldest relict plant in the existing seed plants, and it is one of the most peculiar tree species in woody plants. It is different from other gymnosperms. A common phenomenon is repeated dry clusters. The double stem originates from the fixed latent buds above the stem-root transition zone, and finally germinates to form the double stem, which is a part of individual development and has obvious "anti-young" characteristics, and its growth rate is much faster than that of the mother stem. The re-drying stems are thick and upright, and the occurrence of re-drying can be promoted in a certain way, which can rejuvenate the seedlings and improve the quality and economic value of ginkgo seedlings. [0003] Although the double stem is loc...
