Embodiment 1

[0028] (1) Collect fresh and ripe fruit when the fruit appears slightly yellow in mid-May, put it in a sealed bag, then cover the Kangfengtong fruit in the sealed bag with moss after absorbing enough water, and refrigerate it for 30 days at 5°C. Open the airtight bag for 10 minutes every day to complete post-ripening treatment; take the fruit out of the sealed bag and soak it in clean water at room temperature for 48 hours. After the shell softens, add an appropriate amount of river sand and gently rub it with your hands to separate the shell from the seeds. Use a nylon net to fish out the fruit shells floating on the water surface, add 95% dexon wettable powder and stir gently, and the addition of the dexon is 0.5% of the weight of the mixture of tung tree seeds and river sand , After 3 minutes, the water was filtered off to obtain a mixture of phoenix tung seeds and river sand.

Embodiment 2

[0032] (1) Collect fresh and ripe fruit when the fruit appears slightly yellow in mid-May, put it in a sealed bag, then cover the Kangfengtong fruit in the sealed bag with moss after absorbing enough water, and refrigerate it at 8°C for 7 days. Open the airtight bag for 10 minutes every day to complete post-ripening treatment; take the fruit out of the sealed bag and soak it in clean water at room temperature for 48 hours. After the shell softens, add an appropriate amount of river sand and gently rub it with your hands to separate the shell from the seeds. Use a nylon net to fish out the fruit shells floating on the water surface, add 95% dexon wettable powder and stir gently, and the addition of the dexon is 0.5% of the weight of the mixture of tung tree seeds and river sand , After 3 minutes, the water was filtered off to obtain a mixture of phoenix tung seeds and river sand.

Abstract

The invention discloses a ceodes-grandis seed germination and seedling culturing method. The method includes the following steps that fresh and mature ceodes-grandis fruits are collected and put intoseal bags, then the ceodes-grandis fruits in the seal bags are covered with a moisturizing material, and are refrigerated for 5 days to 30 days at the temperature of 5 DEG C to 8 DEG C, and after-maturation treatment is completed; shells and seeds are separated, the seeds are taken out, fenaminosulf is added, and the mixture is stirred evenly ready for use; the treated seeds are evenly broadcastedon sowing media, the media is covered with soil to cover the media, the product is put into a shade shed, plastic films are covered, the plastic films are removed after seeds germinate, and seedlingsare obtained. According to the ceodes-grandis seed germination and seedling culturing method, the germinating time of the ceodes-grandis seeds is shortened, the emergence rate of the seeds is increased, the seed seedling culturing aim required by artificial cultivation is achieved, artificial cultivation breeding can be developed through sowing, the commercialized production requirement is basically met, and the cultivation propagation expanding aim is 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 phoenix phoenix. Background technique: [0002] Ceodes grandis is an evergreen tree of the genus Ceodes in the family Nyctaginaceae, with a height of up to 14 meters. It is distributed in Taiwan (east) and Xisha Islands in China, and also in India, Sri Lanka, Maldives, Madagascar, Malaysia, Indonesia, northeastern Australia and Pacific islands. [0003] Kangfengtong is the most common arbor tree species in the natural vegetation of the Xisha Islands. It has important ecological, medicinal and ornamental values. It grows fast and plays an important role in wind protection, coastal sand fixation, island climate adjustment and island vegetation restoration. Positive tree species of the genus Kangfengtong has morphological and anatomical characteristics such as thick leaves, low specific leaf area, well...
