Embodiment 1

[0029] The pre-treatment of embodiment 1 hair tree seed.

[0030] (1) Seed collection: In November 2011, 5kg of mature Trichosanthes seeds were collected from Nanjing Zhongshan Mausoleum. The criteria for judging mature seeds are that the seeds are plump and black in color.

[0031] (2) De-flesh and degrease the seeds: Soak the seeds in alkaline water for 2 days and nights, remove the floating empty grains, spread them on the rough concrete floor and step on them manually for 30 minutes, rinse them with clean water, and then soak them in alkaline water for 24 minutes. hour, manually kneading for 20 to 30 minutes, rinsed with water, sieved and dried to obtain 2.3kg of pure seeds.

Embodiment 2

[0032] Example 2: Investigation on the germination rate of the hair stalks after the treatment of the present invention.

[0033] (1) Acid etching treatment: put 1kg of the seeds into a large beaker, add concentrated sulfuric acid, rinse with running water for 4 to 6 hours after reacting for 2 hours, then manually rub to remove acid-etched sundries, and then rinse with clean water for 10 ~ 20 minutes to dry to obtain clean seeds;

[0034] (2) Hormone treatment: the seeds after acid etching in step (1) are divided into 3 batches, soaked in 200mg / L, 400mg / L, 600mg / L gibberellin solution for 2 hours respectively;

[0035] (3) Sand mixing and cold storage: mix the hormone-treated seeds and wet sand at a volume ratio of 1:3, adjust the water content of the wet sand to 35-40%, and store in a refrigerator at 0-5°C for 110 sky.

[0036] (4) Sowing: On March 28, the refrigerated seeds were sifted out, and the seeds were evenly spread in germination boxes (caliber 12×12×6) covered wit...

Embodiment 3

[0039] Example 3 Untreated hair tree germination rate investigation.

[0040] Take 1.3kg of untreated twig seeds and store them mixed with wet sand. The volume ratio of seeds and wet sand is 1:3. Check once every 10 days to keep the water content of the seed sand at about 40%. The seeds were screened out on March 20, 2012, and broadcast live on the seedbed that had been prepared beforehand. The seedbed emergence rate was counted at the end of April, and the results showed that the seedbed emergence rate was almost 0, indicating that the seeds still had deep dormancy.

Abstract

The invention provides a method for sprouting and rapidly seedling a maolai seed, comprising the following steps of: seed collection; seed meat and oil removal; acid etching treatment; hormone treatment; sand mixing and cold storage; sowing; sprout transplantation; and seedling management. By using the method for sprouting and rapidly seedling the maolai seed, provided by the invention, the annual germination rate and planting percent of seeds can be remarkably increased, the seed culturing period can be shortened, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a method for accelerating germination and rapidly raising seedlings of trichosanthemi seeds, belonging to the technical field of tree seedling propagation. Background technique [0002] Cornus walteri is an important woody oil tree species in my country. In plant taxonomy, the hairy tree belongs to the genus Cornus (Cornus) of the Cornaceae family, and is a deciduous tree. It is favored by people because of its high seed oil content. The oil yield of the whole fruit is generally above 33%, while the oil content of the pulp reaches 57.35%. Grease is not only edible (people in Jiangxi, Shandong, and Shanxi have used simple oil extraction to obtain fruit oil for hundreds of years), but can also be used as lubricating oil for machinery and watches, and is also a good raw material for paint. The residue after oil extraction is excellent feed and fertilizer, and the bark and leaves can be extracted to copy glue. The wood is hard an...
