Problems solved by technology

The existing reservoirs, rivers and lakes in my country have various types of sinking areas, and the flooding depth and flooding time of different sinking areas are also very different. Some sinking areas have the characteristics of large flooding depth and long flooding time. Existing technologies are still unable to meet the needs of permanent vegetation construction and ecological management in these water-fluctuating areas, especially in large-depth and long-term flooded water-fluctuating areas.

Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, preferred embodiments of the present invention are described in detail below.

[0015] In the spring of 2007, robust and well-growing verbena and verbena plants were collected in the field, and the seedlings of verbena and verbena were cultivated in the nursery by division propagation. After one year of growth and cultivation, the bred Sufficient numbers of Verbena flat tachycarpa and Verbena seedlings are used to construct the vegetation in the drawdown zone.

[0016]In the spring of 2008, about 15 mu of experimental land was selected in the sinking area of ​​the Three Gorges Reservoir of the Yangtze River (176-145 meters above sea level). The annual average temperature is 17~19℃, the frost-free period is more than 330 days, and the annual rainfall is about 1200 mm. The test plots were located in three test plots, each with different slopes and not exactly the same soil co...

Abstract

The invention belongs to the technical field of protection and governance of ecological environment, and relates to application of Hemarthria compressa and Hemarthria altissima in vegetation construction and ecological governance of water-level-fluctuating zones of reservoirs and rivers and lakes. The vegetation constructed by the Hemarthria compressa and/or the Hemarthria altissima can survive and grow well after being submerged by water with the submerged depth of between 0 and 30 meters and the submerged time of between 0 and 8 months, and can adapt to water and land alternate severe environment; the invention can ensure that developed vegetation survives all the year around in the water-level-fluctuating zones that the vertical height difference of water level fluctuation is 0 to 30 meters and the submerged time is 0 to 8 months, can also steadily retain soil and greatly reduce and fully control soil loss, and is applicable to vegetation recovery and ecological governance of the water-level-fluctuating zones of national reservoirs, particularly Three Gorges Reservoir and rivers and lakes; and the grown Hemarthria compressa and the grown Hemarthria altissima are also excellent animal forage grass.

Description

technical field [0001] The invention belongs to the technical field of ecological environment protection and management, and relates to the application of two plants of the Gramineae Verbena genus in the vegetation construction and ecological management of the water-fluctuation zone, in particular to Verbena flat tachycarpus ( Hemarthria compressa ) and verbena ( Hemarthria altissima ) in the vegetation construction and ecological management of reservoirs and river and lake drawdown areas. Background technique [0002] There are tens of thousands of reservoirs built in my country. Due to the needs of irrigation, power generation, shipping, and flood control, the water level of the reservoirs will fluctuate, resulting in the formation of submerged and water-exposed fading zones alternately on the banks of the reservoirs. Different reservoirs have different water level drops in their drawdown areas, and some reservoirs have water level drops as high as tens of meters in thei...
