Method for planting plant at terrestrial-aquatic transverse zone of river bank

Abstract

The invention relates to the technical field of river bank vegetation recovery, in particular to a method for planting plant at a terrestrial-aquatic transverse zone of a river bank. The method for planting the plant at the terrestrial-aquatic transverse zone of the river bank includes that selecting shrub, arbor and herbaceous plant from March to April at each year; flatting a planting land in a gravel bank land of the terrestrial-aquatic transverse zone of the river bank, wherein the distance between the gravel bank land and the normal water level of the river bank at the dry season is 20 to 200 meters, and the planting region comprises a banded herbaceous plant planting sub-region, a shrub planting sub-region and an arbor planting sub-region parallel to the flow direction of the river water and arrayed in sequence from the river center to the banks; setting planting cavities which are arrayed in Chinese character Pin-shaped in the planting region; obliquely planting the shrub, arbor and herbaceous plant in the planting cavities, wherein the oblique direction is the same with the water flow direction; refilling the excavated sand soil, using a large gravel to cover the surface layer, using gravels to retain at the four sides, using an iron wire net to cover the gravel surfaces and fixing on the river shoal, and watering the plant; watering till the shrub and arbor shoot buds, and reducing the watering times after shooting buds.

Description

technical field [0001] The invention relates to the technical field of river bank vegetation restoration and greening, in particular to a method for planting plants in a river bank water-land transition zone. Background technique [0002] In the prior art, the ecotone refers to the interface area between the inland water ecosystem and the terrestrial ecosystem, which is an ecological transition zone between rivers and highland vegetation, and has obvious edge effects. It is a relatively Relatively special land resources. The water and land ecotone is exposed and flooded periodically, and the water body is scoured seriously, causing a large amount of water and soil loss, causing a large amount of soil near the water body to be washed away, showing an exposed gravel beach, which affects the landscape effect of the water system. It is particularly important to plant vegetation in the water-land ecotone and to increase the vegetation coverage of the water-land ecotone. The tra...

Problems solved by technology

Due to the particularity of the geographic location of the water-land ecotone, grass seeds sown with thin soil layers have a low seedling emergence rate, and shrubs and small trees planted in caves are impacted by water flow during the flooding period and the soil is less likely to appear after the flood period. The phenomenon of lodging, or being bent or even broken by the river floating objects intercepted by itself, seriously affects the landscaping of vegetation and the effect of water and soil conservation, and its application is limited
