specific Embodiment approach 1

[0008] The specific embodiment one: the method that the present embodiment improves the germination rate of Aralia japonicus seeds is realized by the following steps: one, Aralia aralia japonicus seeds are soaked with clear water for 1 to 3 days, then soaked with copper sulfate aqueous solution for 2 to 4 hours, Then rinse with water until the effluent is clear; 2. Mix the washed seeds with wet sand according to the volume ratio of 1:2~4, put them in a ventilated container, and place them under the condition of 3~5°C for cold stratification for 12~16 months , and then put the seeds after sieving out the wet sand under ventilated conditions of 15-25°C to dry for 3-5 days, and then place them under the condition of 3-5°C for sealed storage; 3. Take out the sealed and preserved seeds before sowing, Soak in water for 1 to 3 days; 4. Mix the soaked seeds with wet sand according to the volume ratio of 1:2 to 4, and place them under the condition of a daily temperature difference of 2...

specific Embodiment approach 2

[0009] Specific embodiment two: the difference between this embodiment and specific embodiment one is that in step one, the Aralia japonica seeds are soaked with clear water for 2 days, and then soaked with copper sulfate aqueous solution for 3 hours. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0010] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the mass concentration of copper sulfate aqueous solution in step one is 10 g / L. Other steps and parameters are the same as those in Embodiment 1.

Abstract

The invention discloses a method for improving the germination rate of aralia elata seed, which relates to a method for improving the germination rate of seed, and resolve the existing problem of the low germination rate or germination potential of aralia elata seed which is processed with accelerating ermination. The method includes the steps as follows: 1. the aralia elata seed is first soaked in water, and then in coppersulfate solution and then is washed; 2. the watered seed is mixed with wet sand and processed through low temperature cryoprecipitation, and then dried, sealed and preserved; 3. the sealed and preserved seed is taken out and then soaked in water before seeding; 4. the watered seed is mixed with wet sand and cultivated under the condition of bigger daily temperature difference to germinate, and the watered seed can be sowed. With the method, the germination rate of newly collected aralia elata seed is above 80 percent, and the germination potential is above 58 percent (7 days). The germination rate and the germination potential of the dried aralia elata seed which is processed with the method is respectively are above 75 percent and 55 percent (7 days).

Description

technical field [0001] The invention relates to a method for improving the germination rate of seeds. Background technique [0002] Aralia longya, also known as thorny old crow, is a small perennial deciduous tree in Araliaceae. The roots, root bark and leaves are used as medicine, and the buds are eaten, and the seeds can be squeezed for oil. Aralia japonica seeds are deep dormant seeds. Currently, [0003] In production practice, it is better to artificially treat the seeds of Aralia japonica for germination, which is to change the temperature every day until some seeds germinate, then transfer to stratification treatment at 0-5°C for 4 months. The seeds are first treated with daily temperature-variable stratification, and when some seeds germinate, they are transferred to 0-5°C for 4 months of stratification treatment. The time required for post-ripening of seeds is generally 5-6 months, but Aralia japonica The germination rate of newly harvested seeds is less than 50...
