A kind of method for seed germination and seedling raising of sea mania

Abstract

The invention discloses a method for germinating seeds of suriana maritima L. and growing seedlings. The method includes acquiring the fresh and mature seeds of the suriana maritima L. and carrying out after-mature treatment on the seeds in dry and ventilation places to obtain post-mature treated seeds; soaking the seeds to be germinated in hot water at the temperature of 60 DEG C for 12 hours; fetching the seeds out of the hot water and soaking the seeds in sulfuric acid aqueous solution with the mass fraction of 95-98% for 20-60 minutes; fetching the seeds out of the sulfuric acid aqueous solution and arranging the seeds in gibberellin aqueous solution with the mass fraction of 0.1% for 48-72 hours to obtain pretreated seeds; sowing the pretreated seeds in disinfected culture substrates at the germination temperature of 25-32 DEG C under the control; preserving moisture by means of irrigation or mist spray. A layer of sunshade net is further arranged above the culture substrates. The method has the advantages that the emergence rate of the seeds of the suriana maritima L. can be increased, the seedlings of the suriana maritima L. can be grown from the seeds of the suriana maritima L. in ecological reconstruction procedures for oceanic islands in the South China Sea, can be grown and cultivated by means of seed sowing propagation and can be grown on a large scale, and accordingly the purpose of providing the seedlings of the suriana maritima L. for markets can be achieved.

Description

Technical field: [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for seed germination and seedling cultivation of thalassemia japonica. Background technique: [0002] Suriana maritima L. is an evergreen shrub belonging to the genus Suriana maritima of the family Surianaceae. There are 5 genera and 8 species in the family Seamaniaceae, which are trees or shrubs, and are mainly distributed in Australia and the tropical oceanic islands of the Pacific Ocean. In China, there is a species of seamania, which is only found in the Xisha Islands and Taiwan, China, and is an indicator species for the special habitat of tropical oceanic islands. and construction species; on some newly formed oceanic islands or sandbars due to modern typhoons and other reasons, sea mania is usually the pioneer species in the natural vegetation evolution process of these young islands. Sea man tree is a shrub or small tree with a height of 1...

AI Technical Summary

Problems solved by technology

[0003] However, the natural resources of sea mania in my country's Xisha Islands are very limited, and artificial propagation is also very difficult.

Under normal conditions, the germination rate of sea chinensis seeds is less than 5% within one month after sowing, and there is no report on the propagation technology of sea chinensis seeds, so it is difficult for people to obtain a large amount of them for the reconstruction of the ecosystem of islands and reefs in the South my country Sea. and seedlings necessary for recovery
