specific Embodiment approach 1

[0009] Specific embodiment 1: The method for promoting the germination of Carex sphaerocephalus seeds in this embodiment is completed according to the following steps: 1. Collection and selection of seeds: The seeds of Carex sphaerocephala are collected by the water selection method, and the length of Carex sphaeroides is selected to be 3.5-4 mm. After the seeds are dried, they are stored for 3 to 5 months under a normal temperature environment with a relative humidity of 30% to 50%; 2. Seed treatment: Take out Carex sphagnum seeds after being stored for 3 to 5 months in step 1 Submerge in distilled water, then soak the seeds in an environment of 4~7℃ for 20~50 days, then take out the seeds of Carex sphagnum and wash them with sterile water for 3~5 times, then put in 0.1% mercuric chloride The solution is soaked and disinfected for 8-10 minutes, and then washed with sterile water 4-6 times for later use; 3. Germination: Put the Carex sphagnum seeds treated in step 2 into a germi...

specific Embodiment approach 2

[0011] Specific embodiment two: this embodiment is different from the specific embodiment one. The water selection method described in step one uses a specific gravity of 1.1~1.25g / m 3 Of salt water or yellow mud water. Others are the same as the first embodiment.

specific Embodiment approach 3

[0012] Specific embodiment three: this embodiment is different from specific embodiments one to two in that the drying described in step one uses a seed dryer for drying. Others are the same as the first to second specific embodiments.

Abstract

The invention relates to a method for promoting sprouting of Carex limosa seeds, which relates to the technical field of plant seed sprouting, and aims at solving the problem that the sprouting by adopting the present Carex limosa seed sprouting method is low, and comprises the following steps that: A, collecting and selecting seeds; B, processing the seeds; C, germinating. The method has advantages that: A, automatic collection can guarantee the maturity of t he Carex limosa seeds; B, a water selecting method is adopted to select the seeds, so the quality and the activity of the mature seeds of the Carex limosa can be guaranteed; C, due to the adoption of the sterilization, the mature Carex limosa seeds can be prevented from being moldy; and D, by adopting the technology combining the low-temperature seed soaking and variable-temperature culture, the sprouting speed and the germinating rate of the mature Carex limosa seeds can be improved, and the germinating rate can be improved to 50 percent to 61 percent. The method is applied to the field for promoting the sprouting of Carex limosa seeds in marshes.

Description

Technical field [0001] The invention relates to a method for germination of plant seeds. Background technique [0002] Carex limosa L. is a perennial herbaceous plant belonging to the class of Monocotyledons and Carex of Cyperaceae. It is widely distributed in the wet areas of eastern Eurasia and North America. The main habitat of Carex sphagnum is in the oxbow lakes of the river beaches in hilly areas or in the depressions with perennial water in the plain areas. It is the dominant or associated species in the wetlands of mountain forest areas and grass swamps in plain areas. Carex marsh is an important raw material for forage and papermaking. At the same time, Carex sphaerocephala is a heavy swamp plant that is flooded all the year round. The rhizome reproduces quickly; the individual base leaf sheath is reddish-brown, the leaf has many longitudinal veins, and the surface is folded in half. The male spikelets are linear and upright, and the female spikelets are drooping ovoid....
