Sowing, germination acceleration and rapid seedling growing method of gingko trees

Abstract

The invention provides a rapid seedling growing method of gingko trees and relates to the technical field of seedling growing and planting management of the gingko trees. The rapid seedling growing method comprises the following steps: treating seeds before sowing; sowing in a suitable period; carrying out a sowing technology; and managing after sowing. The rapid seedling growing method is characterized in that in the step of treating the seeds before sowing, the germination acceleration on the seeds adopts a stratification mode; cold frames with the depth of 20cm-30cm are dug at a sun-exposed part and fine sand with the thickness of 10cm is spread at the bottom; a seed-sand mixture is spread in the cold frames for the thickness of 10cm and is covered with one layer of fine sand; an arch shed is established by a plastic film and is sealed, and the temperature in the shed is kept at 18-30 DEG C; a 700-time diluted solution of 70% thiophanate methyl is spread once every 5-7 days and the soil in the arch shed is turned once; and sprouts grow out after 12-20 days. The rapid seedling growing method is simple to operate; the growth period can be prolonged, seedlings are high and the radial growth amount is large; and the economic benefits of seedling growing of the gingko trees can be improved favorably.

Description

technical field [0001] The invention relates to the technical field of planting and management of ginkgo tree seedlings, and relates to a method for sowing, accelerating germination and rapid seedling raising of ginkgo trees. Background technique [0002] Ginkgo biloba is a unique and precious tree species in my country, which is used for seed, leaf and wood. Ginkgo seed kernels are rich in nutrition and can be used both as medicine and food. Since ancient times, they have been the first-class dried fruit for health preservation and longevity, ranking fourth in the production of dried fruits in my country. Ginkgo wood is excellent, known as "silver wood", it is an ideal wood for making handicrafts, moulds, musical instruments and furniture, and its price is relatively high. The ginkgo timber forest 25 years after afforestation can reach 10 cubic meters per mu. Ginkgo is a light-loving tree species with strong drought resistance, but it is not tolerant to waterlogging and w...

Problems solved by technology

Conventional invisible seedling raising methods are common methods of sowing and seedling raising. After the ginkgo seeds are stored, they can be sown after completing the post-ripening stage before sowing. They can be sown without germination. This sowing method is relatively simple and easy to master. However, the emergence is late and irregular, the growth period of seedlings is short, and the yield and quality are slightly poor
