Embodiment 1

[0015] This method is applied in the ginkgo base of Shandong Agricultural University in Tai'an City, Shandong Province. The method of sowing outside the seed coat is adopted. After the ancient ginkgo seeds are collected, they do not need to be peeled, and they are naturally stacked to complete physiological ripening and germinate, eliminating the need for manual labor. The complex process of peeling and germination, and improve the germination rate of ginkgo seeds. The method implementation steps of ginkgo seed band outer seed coat sowing are as follows:

[0016] 1. Collection of Ginkgo biloba seeds

[0017] Tool preparation: seed cloth, high branch shears, bamboo poles

[0018] Seed collection: From September to October, after the seeds of ancient ginkgo trees are mature, select better mother trees to collect and make records.

[0019] 2. Screening of Ginkgo biloba seeds

[0020] According to the size, color, and seed coat of the seeds, the ancient ginkgo seeds used for so...

Abstract

The invention discloses a method for sowing ginkgo biloba seeds with testa of ancient trees. The invention uses the characteristic that gingko biloba seed testa has protective effect on embryo and contains some substances for promoting seed germination; a sowing method of seed with testa is employed; and ancient tree seeds without are unpeeled after collection, and are naturally stacked to complete its physiological after-ripening and germinate. The method eliminates the complex process of artificial peeling and germination, and improves the germination rate of seeds of ginkgo biloba ancient trees. The method uses self protective effect of ginkgo biloba to substitute manual peeling and sand germination, and has the advantages of good effect, simple operations and feasibility.

Description

technical field [0001] The invention belongs to the technical field of tree growth, development and reproduction, in particular to a method for sowing seeds of ancient ginkgo trees outside the belt. Background technique [0002] Ginkgo biloba (Ginkgo biloba L.) is a relict plant of Quaternary glaciers. It is known as a "living fossil" and is the oldest existing higher plant in the world. benefit, ecological benefit and social benefit. As the largest ginkgo country in the world, China has more than 90% of the germplasm resources of ginkgo in the world, and the cultivation history in my country can be verified for thousands of years. At present, the germination of ginkgo seeds is the main method for sowing and propagating ginkgo seeds in the field. Sowing seedlings are also called seedlings, which have a complete root system and terminal buds. The seedlings have strong resistance, fast growth in the later stage, and long life. And this accelerating germination seedling main...
