Problems solved by technology

[0003] The existing vegetation restoration is mainly through sowing grass seeds, and planting shrubs and small trees in holes. However, the bare beach in the water-land transition zone has poor soil. It encounters land drought in the dry season and is flooded in the wet season. The seeds are difficult to germinate or are washed away by the flood. The plant survival rate and preservation rate are low, and the vegetation restoration effect is not ideal

specific Embodiment approach

[0018] The preferred specific implementation of the method for rapid greening of bare beaches in the amphibious zone of the present invention is:

[0019] include:

[0020] Selection of plant species: select herb plants that can propagate through stolons;

[0021] Selection of planting time: The planting time is selected at the time when the temperature is suitable and the beach is exposed, which is conducive to the germination and rooting of the stolons;

[0022] Obtaining plant materials: Collect plant stolons in the field, cut them into segments according to the length of the internodes, and cultivate them in nursery soil. The stolons propagation method can be used to achieve rapid and large-scale multiplication, and the obtained plants will be used for future use;

[0023] Determination of the rapid recovery area: The rapid recovery area is selected as the bare gravel beach in the land-water crisscross zone, and it is at least 10m away from the normal water level of the river during...

specific Embodiment

[0043] In the Lijiang River Basin of Guangxi Zhuang Autonomous Region, a typical water-land crisscross zone was selected to carry out test demonstrations on bare beaches. The specific implementation steps are as follows:

[0044] 1. Selection of plant species. In this experiment, Cynodondactylon was selected for planting. Bermudagrass is a common perennial herb in the Lijiang River, belonging to the genus Bermudagrass. The leaves are lanceolate, the stolon is developed, the expansion ability is very strong, the growth is fast, and it has the characteristics of resistance to flooding, drought, barrenness and trampling.

[0045] 2. Selection of planting time. Planting is selected from February to February, which is the dry season in the Lijiang River Basin, and the temperature is suitable, which is conducive to the growth and development of plants.

[0046] 3. Obtaining plant materials. Collect bermudagrass in the wild, bring it back to the nursery and cut its stolons into 8-10cm l...

Abstract

The invention discloses a method for rapid greening of exposed beach land of land-and-water ecotone. The method comprises the steps: selecting a herbaceous plant capable of breeding through creeping stems; selecting a period, when the atmospheric temperature is appropriate, the beach land is exposed and the germinating and rooting of the creeping stems are facilitated, as planting time; collecting the creeping stems of the plant in the field, chopping the creeping stems into segments according to length of internode, carrying out cultivation by using seeding nursery soil, and realizing rapid large-scale propagation by using a creeping stem breeding manner, so as to obtain plants for later use; selecting exposed boulder beaches, which are far away from the low-water-season mean water level of a river by at least 10m, of the land-and-water ecotone as quick recovery areas; and carrying out land preparation, planting and plant maintenance so as to form stable biocenosis, and then, cultivating part of plants in seeding nurseries, so as to carry out complementary planting on planting furrows and herb grid areas with silted river sand in spring next year. According to the method, the rapid greening of the exposed beach land of the land-and-water ecotone can be realized, the vegetation coverage is improved, both moisture and soil are conserved, the stable biocenosis is gradually constructed, and ecological restoration is promoted.

Description

Technical field [0001] The invention relates to a water and soil conservation and ecological restoration technology, in particular to a method for rapid greening of bare beaches in a land-water interlaced zone. Background technique [0002] The land-water crisscross zone refers to the functional interface area between aquatic ecosystems and terrestrial ecosystems. There are many kinds of organisms, which can purify water quality, protect groundwater, maintain species diversity, stabilize river banks, reduce flood disasters, regulate regional microclimate, soil and water conservation, landscape tourism, etc. Aspect function. As the water level changes with the seasons, the land-water crisscross zone will be periodically inundated and exposed, and soil erosion will then occur and further form exposed gravel beaches, destroying the ecological and landscape functions of the land-water crisscross zone. Therefore, bare beaches are realized. It is particularly important to increase the...
