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...

Examples

Embodiment 1

[0017] A method for improving ginkgo seed germination rate, comprising the following steps:

[0018] (1) Take a complete mussel shell with a length of 8cm and a width of 5cm, wash it, and divide it into two halves after ultraviolet disinfection;

[0019] (2) Put a sterilized ginkgo seed in each water clam shell, and then cover the seed with nutrient soil, wherein the nutrient soil is made of the following components by weight: 20 parts of earthworm soil, 8 parts of Yu Yuliang part, 0.3 part of seaweed extract;

[0020] (3) Put the water clam shells into the greenhouse, and control the temperature in the greenhouse to 23°C on the 1st-3rd day, control the temperature in the greenhouse to 27°C on the 4th-8th day, and then control the temperature in the greenhouse to 25°C The humidity in the control greenhouse was 70% on the 1st-8th day, and then the humidity in the control greenhouse was 75%; the concentration of carbon dioxide in the control room was 500ppm on the 1st-8th day, ...
