Abstract

The invention discloses a fosbergia shweliensis seed processing and germination accelerating method. The method comprises the following steps that cones are picked in October to November of the current year, the overall cones are placed in a shady and cool place at 15-20 DEG C to be spread out and preserved after being picked, and the cones are turned over for one time every week to avoid mildew; the cones are placed until May to June of the next year, cone seeds are sown in a sand bed after being peeled off, washed clear and dried, and the sowing thickness does not exceed one centimeter; sand with the thickness of 1-2 centimeters is evenly sprinkled after sowing is completed, after thorough watering is performed, an arched shed is built and covered with thin film for germination accelerating, and after one month, germinated seeds are selected for spot sowing, and non-germinated seeds are still covered with the thin film for germination accelerating. According to the fosbergia shweliensis seed processing and germination accelerating method, the endangered status of a fosbergia shweliensis tree species is relieved, and the seed germination capacity of the tree specie is effectively improved.

Description

The alizarin seed treatment in a kind of Ruili and germination accelerating method

Technical field

The present invention relates to alizarin cultivation field, Ruili, be specifically related to the alizarin seed treatment in a kind of Ruili and germination accelerating method.

Background technology

The alizarin Fosbergiashweliensis base in Ruili is called Randiashweliensis, and the different name Baoshan is alizarin, and Yunnan is peculiar.Ruili madder is the alizarin Pterostyrax plant of Rubiaceae, shrub or dungarunga, and Gao Keda 10 meters, in June at florescence, seed is ripe at Second Year.Originate in From Western Yunnan; Be born in small stream limit, the mountain valley sparse woods at height above sea level 1800-2000 rice.

Qian Shi Yunnan, Ruili endemic species, its narrow distribution range, quantity is few.The alizarin seed in Ruili is just ripe at Second Year; therefore; a lot of seed is eaten up (if not by animal or man-made hazard by mouse or other animal as food in the winter time; seed does not generally fall; hang 4-5 in the tree always), Seed storage negligible amounts or do not have, natural regeneration difficulty; be in Critical Condition, be classified as minimum population species rescue protective plan outline (2010-2020) in Yunnan Province by Yunnan Province.

Summary of the invention

In order to remove the Endangered status of the alizarin seeds in Ruili, the invention provides the alizarin seed treatment in a kind of Ruili and germination accelerating method, effectively can improve the germination capacity of seeds of these seeds.

For achieving the above object, the technical scheme that the present invention takes is:

The alizarin seed treatment in a kind of Ruili and germination accelerating method, comprise the steps:

S1, then October-November carries out cone harvesting, and preservation is spread in the place after harvesting, whole cone being placed on the cool place of 15-20 DEG C out, stirs weekly once, avoids mouldy, be placed into Second Year 5-6 month, obtain seed in cone; After testing, the seed now in all cones is all ripe, and germination rate can reach more than 85%, and the percentage of seedgermination do not processed is less than 50%.

S2, by the cone seed strip off of step S1 gained, clean, sow on husky bed after the water purification that dries in the air divides, sow and be thickly no more than 1 centimetre;

S3, sowed the rear sand evenly sprinkling 1-2 cm thick, and covered shed film and carry out vernalization, the seed sprouted had been selected program request in one month, continuing of not sprouting covers film vernalization.

Wherein, the wide of described husky bed is 90 centimetres, and length is determined according to landform.

Wherein, the sand of described husky bed adopts not containing the river sand of earth, and sand laying depth is 30-50 centimetre.

Preferably, comprise the steps:

S1, then mid-October carry out cone harvesting, and preservation is spread in the place after harvesting, whole cone being placed on the cool place of 17.5 DEG C out, stirs weekly once, avoids mouldy, are placed into Second Year mid-May, obtain cone seed;

S2, by the cone seed strip off of step S1 gained, clean, sow on husky bed after the water purification that dries in the air divides, sow and be thickly no more than 1 centimetre;

S3, sowed the rear sand evenly sprinkling 2 cm thicks, water permeable after, build shed and cover film and carry out vernalization, the seed sprouted was selected program request in one month, continuing of not sprouting covers film vernalization.

Preferably, sand laying depth is 40 centimetres

The present invention has following beneficial effect:

Carry out cone harvesting in October-November, well avoid the harm of wildlife, simultaneously by rational cone and vernalization treatment technology, relieve the Endangered status of the alizarin seeds in Ruili, effectively raise the germination capacity of seeds of these seeds.

Embodiment
