Method for improving germination rate of ginkgo seeds

Abstract

The invention discloses a method for improving a germination rate of ginkgo seeds. The method comprises the following steps: (1) taking a complete clamshell with the length of 8-10cm and the width of 5-7cm, washing the clamshell, performing ultraviolet disinfection, and separating the clamshell into two halves; (2) putting a disinfected ginkgo seed into each clamshell, and covering the seed by using nutrient soil; and (3) treating the clamshell in a greenhouse. According to the method provided by the invention, the germination rate of the ginkgo seeds can reach 87% and is improved by about 15%, germination of the ginkgo seeds can be accelerated, and the seedling growing period is shortened.

Description

technical field [0001] The invention belongs to the field of tree planting, and in particular relates to a method for improving the germination rate of ginkgo seeds. Background technique [0002] Ginkgo tree is a rare and precious tree species, and it is also a special economical fruit tree in my country. Since 2008, due to the vigorous development of urban greening in my country, the price of ginkgo trees has directly increased. Due to the continuous increase in the price of large-scale ginkgo trees, the price of leaves of ginkgo seedlings has also continued to increase in recent years, resulting in a soaring price of ginkgo seedlings, which greatly stimulated the enthusiasm of farmers to plant ginkgo trees, and greatly improved the farmers' cultivation Positivity of seedlings. [0003] When Ginkgo is used as seedlings for large-scale greening, it often adopts the propagation method of sowing, so that a large number of seedlings can be obtained, but the germination rate o...

Problems solved by technology

[0003] When Ginkgo is used as seedlings for large-scale greening, it often adopts the propagation method of sowing, so that a large number of seedlings can be obtained, but the germination rate of Ginkgo seeds is reduced. After the seeds grow new shoots, they are easily attacked by soil microorganisms and die

Moreover, the ginkgo seeds after winter are in deep dormancy. Before sowing, they need to be mixed with sand to accelerate germination. This method will increase the risk of ginkgo seeds being infected with germs, and the germination effect is not obvious, resulting in a low germination rate of ginkgo. Only 72%, and the germination period is long, with an average germination period of about 10 days, causing huge economic losses to growers
