Embodiment 1

[0020] Cold Workout Treatment of Ginkgo Seeds

[0021] 1 kg of ginkgo seeds and 2.5 kg of snow are evenly mixed and then put into a wooden box and hidden in an underground kiln, and the seeds are subjected to cold stress treatment; the storage time is 90 days. When it is close to the time of sowing, when the temperature reaches above 10°C from the end of April to the beginning of May, the seeds are taken out of the cellar to cool in the sun, watered to keep the temperature at 20-22°C, and under saturated humidity conditions, the seeds will be cracked and germinated. Sow when more than one seed has cracked.

Embodiment 2

[0023] Ginkgo Seedbed Management

[0024] For bed preparation, the width of the bed is 1m, the length is determined according to the ground, and the length is 10m to 20m, the width of the trail is 0.5m, and the height of the bed is 20cm. Build a slope with a 45° angle around the bed, smooth and compact the sowing surface and the surrounding slope with a wooden trowel, and disinfect the bed surface with ferrous sulfate: 18 kg of ferrous sulfate per mu. use;

Embodiment 3

[0026] Adopt on-demand sowing or drill sowing to evenly scatter the seeds treated in Example 1 on the bed surface trimmed in Example 2, about 550 grains per square meter, and cover the seeds with crushed, sterilized, and dewormed horse manure after sowing , thickness 5cm.

[0027] In late autumn, from September to November, when the ground temperature is above 5°C, fill the ginkgo seedbed with antifreeze water prepared by 1-3% equivalent nitrogen, phosphorus, and potassium ratio of 97-99%; About 11cm, or bury the ginkgo seedlings in sand to keep out the cold. The thickness of the buried sand is about 13cm. Wrap the annual ginkgo with plastic film, and then cover it with grass curtains to keep out the cold.

[0028] In spring, when the temperature is 5-10°C, the ginkgo seedbeds are irrigated and thawed; at 10-15°C, the anti-cold soil and sand are removed, and the plastic film wrapping layer is kept; when the temperature reaches 15-18°C, the plastic film wrapping layer is remove...

Abstract

The invention provides a south-north transfer method for maidenhair-trees which comprises, carrying out exercise treatment to the ginkgo seeds so as to facilitate the cracking of the seeds, spreadingthe seeds uniformly onto the dressed bed surface through the modes of dot seeding or row seeding, filling antifreeze water to the ginko seed bed, burying the ginko seedling with soil or sand and covering with straw curtains for cold-proofing, unfreezing the filled water to the ginko seed bed in spring at 5-10 deg. C, removing cold-proof soil, sand and plastic foil bundled layer, finally carrying out transplanting.

Description

technical field [0001] The invention relates to a south-to-north migration, introduction and cultivation method of ginkgo, an endangered tree species in my country, and in particular provides a cultivation method for cold tempering of ginkgo trees and antagonizing physiological drought. The invention belongs to the technical field of plant cultivation and cultivation. Background technique [0002] Ginkgo biloba L., also known as ginkgo and gongsun tree, originated in my country and is a rare tree species unique to my country. Its taxonomic status belongs to Gymnospermae (Gymnospermae) Ginkgopsida (Ginkgopsida); Ginkgoales (Ginkgoales); Ginkgoaceae (Ginkgoaceae); this section has only one genus and one species. [0003] There are many strains of ginkgo and good stress resistance. Ginkgo plants were introduced and cultivated in my country more than 2,000 years ago. Ginkgo plants are distributed in many areas of my country (N.21°30′-41°46′, E.97°-125°). The reason for the lo...
