Problems solved by technology
[0003] However, the germination rate of reed under natural conditions is very low, generally between 3-5%, and it is impossible to achieve effective sowing
The existing method of using reeds for ecological restoration is mainly to transplant the rhizomes of mature reeds, and transplanting reeds requires a lot of manual digging, transportation and planting, which has high costs, high mortality, and damage to the ecology of the seedling harvesting area. The problem

Embodiment 1
[0048] Reed seeds with full grains were selected, soaked in 500 mg / L gibberellin aqueous solution under light conditions at 28°C for 12 hours, and then soaked at 24°C for 12 hours under dark conditions; the treated reed seeds were obtained.
Embodiment 2
[0050] The reed seeds with full grains were selected, soaked in 400mg / L gibberellin aqueous solution under light conditions, 28°C for 6 hours, and then soaked in dark conditions at 22°C for 6 hours; the treated reed seeds were obtained.
Embodiment 3
[0052] The reed seeds with full grains were selected, soaked in 600mg / L gibberellin aqueous solution under light conditions, 28°C for 9h, and then under dark conditions, 24°C for 9h; the treated reed seeds were obtained.

The invention discloses a method for promoting the germination of reed seeds and improving salt tolerance. The invention finds that the reed seeds are soaked in an aqueous solution of gibberellin with a concentration of 100 mg / L-600 mg / L for 12-36 hours before sowing, The germination rate of reed was greatly increased, the germination speed was accelerated, and the salt tolerance was significantly improved. Due to the wide source of reed seeds, low cost and simple gibberellin treatment conditions, it is easy to process in large quantities. Using the method of the present invention to obtain a large number of reed seeds with high germination rate and high salt tolerance is very suitable for ecological restoration projects in saline soil areas, and is also suitable for wetland ecological construction in non-saline soil areas, and the planting operation is also very simple. with broadly application foreground.
Description
technical field [0001] The invention relates to the technical field of plant seed treatment and ecological restoration, in particular to a method for promoting reed seed germination and improving salt tolerance. Background technique [0002] Phragmites reed is a perennial herbaceous plant of the Poaceae family, which is widely distributed in the world. In the natural habitat, it mainly reproduces with rhizomes. The rhizomes criss-cross to form a network. Under suitable conditions, it can still develop into new branches and adapt to different ecological environments. Reed has strong environmental protection functions such as water purification, soil binding, and providing living space for animals, plants, and microorganisms. At the same time, reed is a very important plant in landscaping and ecosystem restoration in agricultural areas. Plant material in shallow waters and riparian buffers has been grown extensively throughout the world. Phragmites reed is also a plant with ...
