Buy ginkgo seed "six wants"
Ginkgo biloba, also known as ginkgo and Gongsunshu, is a gymnosperm plant and is the only living fossil plant in China. Its long life span, strong adaptability, wide use, strong disease resistance, and easy management make it an excellent tree species that integrates ecological, social and economic benefits. In the process of breeding Ginkgo biloba seedlings, seed quality is the key to the success or failure of breeding. Therefore, the fruit growers should have the following "six essentials" when purchasing ginkgo seeds. One must buy new seeds. That is to say, the seeds that were harvested in the same year were purchased from Ginkgo biloba mother trees (the best mother trees with a tree age of 80 years). Second, buy good seeds for pollination. Ginkgo seeds are cut open to see if there are germs in the endosperm. If there are no germs, they cannot be used to sow seedlings. Third, we must buy seeds after weeding. That is to buy the seeds to remove debris. Fourth, buy moderately sized seeds. Generally, about 400 to 700 seeds per kilogram of Ginkgo biloba seed are suitable, and the harvested seeds are to be peeled and dried, and the north is suitable for spring sowing after stratification. Fifth, we must buy the seed of the seed tree. The mother tree is well pollinated, has a sound seed structure, and has a high embryo rate. After seeding, the seedlings are seeded and seedlings are strong. They have strong adaptability after nursery, and the insurance coefficient after planting is high. Sixth, buy ginkgo seeds that have been identified by experts or relevant technical personnel.
