Problems solved by technology

Because white sandalwood seeds have obvious dormancy habits and high oil content, which affects seed germination, the dormancy period of white sandalwood seeds is generally 2 years in the natural environment, the seed germination rate is about 20%, and the survival rate of seedlings is about 10%. The cultivation of seedlings brings certain difficulty, and becomes the main restriction factor of this plant introduction cultivation and application promotion, makes the white sandalwood seedlings on the market tight.
At present, there are relatively few research reports on white sandalwood, and there has been no report on artificially inducing the germination of white sandalwood seeds to improve the germination rate of white sandalwood seeds and the survival rate of seedlings

Embodiment 1

[0024] A method for raising seedlings of white sandalwood seeds, comprising the following steps:

[0025] ⑴ Seed harvesting: In October, choose mature white sandalwood as the mother tree for seed collection, and collect mature seeds with plump seeds and blue-black color.

[0026] (2) Seed dewaxing treatment: After harvesting, stack the seeds collected in step (1) and stack the collected seeds together, cover the seed pile with plastic film, compact it around, and remove it after 3 to 5 days Plastic film, at this time, the exocarp of the seed fruit rots and becomes soft; put the softened seed fruit into a screen-shaped cloth bag, the mesh hole diameter of the cloth bag screen is smaller than the size of the seed, and each bag is filled to 2 / 3 to 3 / 4 Tighten the bag near the mouth of the bag with a rope; wash the cloth bag containing the seeds repeatedly in clean water at 20-25°C to remove the peel, pulp and impurities, and get the seeds; after cleaning the seeds, select the ful...

Embodiment 2

[0034] A method for raising seedlings of white sandalwood seeds, comprising the following steps:

[0035] (1) Harvesting the seeds: the same as the content of "(1) Harvesting the seeds" in Example 1.

[0036] (2) Seed dewaxing treatment: the same as the content of "(2) Seed dewaxing treatment" in Example 1.

[0037] (3) Seed temperature change treatment: In late November, put the seeds stored in step (2) in clear water at 30°C, cool to room temperature naturally and soak for 24 hours to remove the seeds floating on the water surface; put the soaked seeds in bags into- After freezing for 24 hours in a freezer or freezer at 2°C, take it out and let it thaw naturally at room temperature, then place the thawed seeds in clean water at 30°C, cool to room temperature naturally and soak for 12 hours, then remove and drain the water , store in a ventilated and cool place to dry and store for later use.

[0038] ⑷Seed wet sand stratification cold storage: Sprinkle and mix the seeds st...

Embodiment 3

[0042] A method for raising seedlings of white sandalwood seeds, comprising the following steps:

[0043] (1) Harvesting the seeds: the same as the content of "(1) Harvesting the seeds" in Example 1.

[0044] (2) Seed dewaxing treatment: the same as the content of "(2) Seed dewaxing treatment" in Example 1.

[0045] (3) Seed variable temperature treatment: In late November, place the seeds stored in step (2) in clear water at 40°C, cool naturally to room temperature and soak for 36 hours to remove the seeds floating on the water surface; put the soaked seeds in bags into- After freezing for 36 hours in a freezer or freezer at 4°C, take it out and let it thaw naturally at room temperature, then place the thawed seeds in clean water at 40°C, cool to room temperature naturally and soak for 18 hours, then remove and drain the water , store in a ventilated and cool place to dry and store for later use.

Abstract

The invention relates to a seedling growing method of seeds of symplocos paniculata. The technical problems in the prior art that the seeds of symplocos paniculata are low in germination rate, grown seedlings are low in survival rate and the like in a natural environment are solved. The invention provides the seedling growing method of the seeds of symplocos paniculata, and the method comprises the first step of harvesting fruits, the second step of conducting dewaxing treatment on the fruits, the third step of conducting seeds temperature varying treatment, the fourth step of conducting accumulation and cold storage on seed humid sand layers; the fifth step of accelerating germination; the sixth step of sowing seeds and conducting seedling growing management. The seedling growing method of the seeds of symplocos paniculata can be widely applied to the technical field of seedling propagation of symplocos paniculata.

Description

technical field [0001] The invention belongs to the technical field of seedling breeding, and in particular relates to a seedling raising method of white sandalwood seeds. Background technique [0002] White sandalwood, scientific name Symplocos paniculata (Thunb.) Miq., has another name called ash wood, broken seed tree, etc., and is a deciduous shrub or small tree of the genus Thunb. Distributed in Northeast China, North China and Jiangnan. White sandalwood has a beautiful shape, with white flowers in spring and blue fruits in autumn. It is resistant to drought and barrenness. It has a well-developed root system and strong soil-fixing ability. Ideal tree species for soil erosion and ecological environment improvement. This tree species has strong fecundity, resistance to mowing, high calorific value, and good quality of firewood forest. The seeds can be used as medicine, which has the effects of clearing away heat and detoxification, regulating qi and dispelling stagnat...
