A kind of method for preserving the seeds of chrysanthemum

Abstract

The invention relates to a seed storage method, and concretely relates to a ruppia sinensis seed storage method. According to the invention, distilled water and a seawater element are used for preparing high-salinity artificial seawater which is used for disinfecting water body; after matured ruppia sinensis seeds exocarp is completely decayed, the seeds are flushed, the cleaned ruppia sinensis seeds are placed in a sealed container filled with the disinfection artificial seawater; finally the temperature of the artificial seawater for immersing the ruppia sinensis seeds is kept at 0 DEG C, and the seeds are stored in dark place. During seed storage, water is regularly changed, and the decayed seeds are cleaned. The reservation rate of the ruppia sinensis seeds during a storage period is increased by the method, high vitality and quality of the seeds can be kept, the simple and effective ruppia sinensis seed storage method can provide high quality ruppia sinensis seeds for artificial sowing, is in favor of recovery or reconstruction of an underwater vegetation ruppia sinensis grassland, and provides necessary technical support for rapidly recovering good ruppia sinensis grassland ecological environment.

Description

technical field [0001] The invention relates to a seed preservation method, in particular to a seed preservation method of Ruppiasinensis Ruppiasinensis. Background technique [0002] Seagrass meadows ecosystem, mangrove forest and coral reef ecosystem are considered to be three typical offshore marine ecosystems. And international research results show that the ecological service value of seagrass fields is significantly higher than that of mangroves and coral reefs. The "seaweed" mentioned here refers to the only angiosperm submerged in shallow sea water, which differentiates into organs such as roots, stems, leaves, flowers and seeds, and "seaweed" as lower plants (such as kelp, enteromorpha, etc.) very different. Lush seagrass fields are like forests on land, an important symbol of a healthy marine environment, and are precious "undersea grasslands" or "undersea forests". Seagrass fields are high-productivity areas that can provide good habitats, nursery grounds and s...

AI Technical Summary

Problems solved by technology

According to the results of field observation, although the yield of the seeds of S. chinensis is very high under natural conditions, many seeds germinate in late summer and early autumn. The seedlings cannot resist the dry exposure in summer and the cold in winter, and the seedling rate is very low.

In the spring of the second year, the remaining 25% of the seeds buried in the bottom mud will germinate again, and the seedlings at this time can form adult plants with reproductive ability, resulting in the inability to increase or even reduce the population of S.

At present, there is also a lack of effective long-term preservation methods for the seeds of S.
