Embodiment Construction

[0014] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0015] A rapid seedling raising method for sowing and accelerating germination of ginkgo trees, comprising the following steps,

[0016] Seed treatment before sowing: select and germinate the seeds in early and mid-February;

[0017] Sowing at the right time: sowing can be completed before the vernal equinox. The sowing density is determined according to the purpose of cultivation. When cultivating seedlings that are out of the nursery in the current year, 30,000 plants per mu are sown; when cultivating 2-3 year old seedlings for grafting, 1.5 -20,000 plants;

[0018] Sowing technique: soil preparation, bed making, ditching, soil disinfection. Before sowing, the ginkgo radicle is cut from 0.3 cm below the root neck, and then sowed on demand. The ...

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...
