Problems solved by technology
[0007] 1) There is a lack of ecological restoration technology in the water-fluctuating zone of the reservoir;
[0008] 2) It is difficult to select plants for ecological restoration in the water-fluctuation zone of the reservoir. It is difficult to find plants suitable for the water-fluctuation zone of the reservoir. It has a certain effect on the landscape ecology and soil erosion in the water-fluctuating zone of the reservoir

Embodiment Construction
[0078] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0079] 1. Through the indoor and outdoor simulation experiments of scorpion grass, the research on its growth law and the research of demonstration projects to test the adaptability of scorpion grass to the water-fluctuation zone of the reservoir
[0080] 1. Carry out long-term water-flooding experiments in winter
[0081] 1.1 Experimental method
[0082] Place the cultivated scorpion grass in a plastic bucket with a diameter of 62 cm and a height of 82 cm and fill it with clear water. The top of the scorpion grass is 0.3 m above the water surface;
[0083] Beginning in October, a 180d complete flooding experiment was carried out. After the plants were completely flooded for 30d, 60d, 90d, 120d...

The invention discloses a method for restoring a hydro fluctuation belt of a reservoir using phalaris arundinacea. The method comprises testing the adaptability of phalaris arundinacea in a hydro fluctuation belt of a reservoir through indoor/outdoor simulation test on the phalaris arundinacea, and determining that the phalaris arundinacea can be cultivated in the hydro fluctuation belt of the reservoir; cultivating the phalaris arundinacea in the hydro fluctuation belt of the reservoir; and carrying out daily nutrient and water management on the phalaris arundinacea after cultivation. The phalaris arundinacea which is suitable for cultivation in the hydro fluctuation belt of the reservoir is found through systematic research, the phalaris arundinacea can adapt to the growing environment of the hydro fluctuation belt of the reservoir that is flooded in water and exposed for a long term, and the phalaris arundinacea can grows to a certain biomass, so the phalaris arundinacea can protect the landscape ecology and reduce water and soil loss in the hydro fluctuation belt of the reservoir. A method for cultivating phalaris arundinacea in hydro fluctuation belt of a reservoir is high in transplanting survival rate, and the phalaris arundinacea can efficiently thrive in the hydro fluctuation belt.
Description
technical field [0001] The invention relates to a method for repairing a water-fluctuation zone of a reservoir, in particular to a method for repairing a water-fluctuation zone of a reservoir by using sage grass, and belongs to the technical field of environmental protection. Background technique [0002] Phalaris arundinacea (Phalaris arundinacea), also known as grass reed, garden grass reed, is a perennial grass of the genus Phalaris (Phalaris), with rhizomes; the stems are erect, thick, 60-150cm high, and the stem nodes of the cluster can Rooting and growing branches, strong stress resistance. Leaf sheaths are glabrous; blades are 5-15mm wide, gray-green. Panicle dense and narrow, 8-15cm long, densely branched with spikelets; spikelets 4-5mm long, containing 3 florets, 2 sterile lemmas degenerated into strips at the bottom, terminal bisexual; gliaceous, etc. Long, rough on the ridge, with very narrow wings on the upper part; lemma cartilaginous, broadly lanceolate, 3-4m...
