Seed coating method with function of improving germination characteristics of gingko seeds

Abstract

The invention discloses a seed coating method with a function of improving germination characteristics of gingko seeds. The method comprises following steps: (1), seed pretreatment; (2), preparation of a coating agent; (3), coating treatment; (4) treatment after the coating. The seed coating method with the function of improving the germination characteristics of the gingko seeds is provided, withthe adoption of the coating process, activity of the gingko seeds is improved, dormancy of the gingko seeds is broken, the germination characteristics of the gingko seeds are improved, nutrient absorption characteristics, disease resistance and stress resistance of gingko are enhanced, and the method has lasting high efficiency and has market popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of seed coating, and in particular relates to a seed coating method for improving the germination characteristics of Ginkgo biloba seeds. Background technique [0002] Ginkgo tree, also known as ginkgo tree, is the oldest gymnosperm left over from the glacier movement in the fourth century and is one of the most precious tree species in the world. Ornamental, economical and medicinal value. However, ginkgo trees grow slowly, and ginkgo seeds have dormancy characteristics. When the seeds are mature, the embryos are not fully differentiated. Therefore, if the picked seeds are directly sown, the germination rate is very low, only about 40%. Before sowing, treat the ginkgo seeds. , is a common way to improve the germination rate of ginkgo seeds, but the treatment effect is not very significant, and there are still many drawbacks. [0003] Nowadays, there are many methods to improve the germination rate of gink...

Problems solved by technology

However, ginkgo trees grow slowly, and ginkgo seeds have dormancy characteristics. When the seeds mature, the embryos have not yet fully differentiated. Therefore, if the picked seeds are directly sown, the germination rate is very low, only about 40%. Ginkgo seeds are treated before sowing , is a relatively common way to increase the germination rate of ginkgo seeds, but the treatment effect is not very significant, and there are still many disadvantages

[0003] Nowadays, there are many ways to improve the germination rate of ginkgo seeds and strengthen ginkgo seeds. Most of them are soaked in seed soaking liquid, and assisted by other conventional physical methods to treat ginkgo seeds, so as to break the dormancy of ginkgo seeds and increase the germination rate of ginkgo seeds. Shorten the germination time of the seeds, but the improvement effect is not significant enough. Although the germination rate of the seeds has increased, the seed vigor has not improved. In the later growth and development, there are still many problems, such as the invasion of diseases and insect pests, slow growth, etc. At this time, it is necessary to use a certain amount of fertilizers and insecticides and fungicides to maintain the growth of the plants in the subsequent growth and development process, which will not only cause great damage to the plants and the soil environment, but also waste a lot of resources.

For example, application number 201510454200.9 discloses a method for accelerating germination of ginkgo seeds. The method of the present invention can effectively break the dormancy of ginkgo seeds and improve the germination rate of ginkgo seeds. However, in practical applications, it is found that this method cannot improve the nutrient absorption characteristics of ginkgo. The growth and development of ginkgo seedlings did not significantly improve
