Embodiment

[0078] Embodiment A kind of method of utilizing bermudagrass to restore the water-fluctuation zone of the reservoir

[0079] (1) Investigate and screen plants in the water-fluctuating zone of the reservoir

[0080] 1 Investigation and screening of vascular plants in the water-fluctuating zone of the reservoir

[0081] 1.1 Investigation method

[0082] From May to August 2011, December 2011 and August 2013, the distribution of plant species in the water-fluctuation zone of Baihua Lake was investigated, and the life forms of the species were counted.

[0083] 1.2 Composition characteristics of vascular plants in the water-fluctuation zone of Baihua Lake Reservoir

[0084] Taking the water-fluctuating zone of Baihua Lake Reservoir in Guiyang City, Guizhou Province as the research object, the study area is rich in species, with 147 species of vascular plants belonging to 49 families and 116 genera. The study area is dominated by angiosperms, with a total of 43 families, 110 gen...

Abstract

The invention discloses a method for repairing a reservoir hydro-fluctuation belt by use of bermuda grass. The method comprises steps of firstly investigating and screening plants on the reservoir hydro-fluctuation belt of the Baihua lake so as to screen out plants capable of growing on the reservoir hydro-fluctuation belt; then carrying out indoor and outdoor simulation experiments for the bermuda grass so as to detect adaptability of the bermuda grass to the reservoir hydro-fluctuation belt, and determining that the bermuda grass can be planted on the reservoir hydro-fluctuation belt; and at last, cultivating the bermuda grass on the reservoir hydro-fluctuation belt and performing ecological repairing on the reservoir hydro-fluctuation belt. In this way, via systematical research, it is found that the bermuda grass is capable of growing on the reservoir hydro-fluctuation belt which has been soaked in water and exposed to water for a long time, and with certain biomass, the bermuda grass can largely protect landscape ecology of the reservoir hydro-fluctuation belt and preventing water and soil loss.

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 bermudagrass, and belongs to the technical field of environmental protection. Background technique [0002] Bermudagrass (Cynodondactylon (Linn.) Pers.), also known as Bermuda, Bermudagrass is a perennial grass plant; the root system is developed, and it is an excellent soil-fixing and slope protection plant; it has strong vitality, rapid reproduction, and grows in patches. Resistant to trampling, can be propagated by seed sowing or grass stems, mainly asexual reproduction; it has cold resistance, drought resistance, disease resistance, insect resistance, salt and alkali tolerance, shade tolerance, heat tolerance and herbicide resistance Performance and other traits; it mostly grows near villages, roadside river banks, and wasteland hillsides. Bermudagrass is a long-lived peren...
