Embodiment 1
[0034] Embodiment 1: a kind of halophytic grass seedling cultivation method, its main feature is to comprise the following steps:
[0035] A. Seed preparation:
[0036] Sterilize the surface of Saltwort seeds with 75% alcohol for 30 seconds, remove the alcohol, let the seeds dry naturally at room temperature, mix the dried seeds with sterilized fine sand in a volume ratio of 1:10 and prepare for planting;
[0037] B. Culture substrate preparation:
[0038] Mix the sterilized fine sand and vermiculite at a volume ratio of 1:0.8 and use it as a culture substrate, put it into a culture pot, then move the culture pot into a tray, and fill the tray with distilled water to soak the culture substrate;
[0039] C. Germination of seeds covered with film:
[0040] Spread halophytic grass seeds evenly mixed with fine sand on the surface of the culture substrate, spray distilled water with a watering can to soak; then cover the culture pot with a film, and place it in a light intensity ...
Embodiment 2
[0053] Embodiment 2: a kind of halophytic grass seedling cultivation method, its main feature is to comprise the following steps:
[0054] A. Seed preparation:
[0055] Surface sterilize the seeds of saline grass with 75% alcohol for 60 seconds, remove the alcohol, dry the seeds naturally at room temperature, mix the dried seeds with sterilized fine sand in a volume ratio of 1:20 and prepare for planting;
[0056] B. Culture substrate preparation:
[0057] Mix the sterilized fine sand and vermiculite in a volume ratio of 1:1.2 and use it as a culture substrate, put it into a culture pot, then move the culture pot into a tray, and fill the tray with distilled water to soak the culture substrate;
[0058] C. Germination of seeds covered with film:
[0059] Spread halophytic grass seeds evenly mixed with fine sand on the surface of the culture substrate, spray distilled water with a watering can to soak; then cover the culture pot with a film, and place it in a light intensity ...
Embodiment 3
[0073] Salt grass seeds are surface sterilized with 75% alcohol for 60 seconds, mixed with fine sand at a ratio of 1:1 and spread on the surface of the culture substrate, sprayed with distilled water to infiltrate, covered with plastic film on the upper edge of the culture pot, and placed in a culture tray filled with distilled water . Moved into light intensity about 300ummol / m 2 , germinate in a greenhouse with a light time of 16 hours, a temperature of 22°C, and a humidity of 60%. When most of the seedlings are 1.0 cm long, the covering film is removed. The thickness of the sand covering the roots of the seedlings is about 0.4cm. Spray 1 / 2 Hoagland nutrient solution on the surface of the seedlings every day for 12 days, and a few seedlings have 4-6 leaves. The volume ratio of seedling culture substrate is fine sand: vermiculite = 1:0.8.
[0074] Under the above culture conditions, the germination rate of halophytic grass seedlings was 100%, the survival rate was 70.0%, a...
