Red Beach wetland saline-alkali soil suaeda heteroptera ecological repair method

Abstract

The invention discloses a Red Beach wetland saline-alkali soil suaeda heteroptera ecological repair method. Soil is improved through methods of fertilizing, soil turning and like, after the severely degraded wetland soil is improved, saline land suaeda salsa can successfully grow, deep tillage can obviously lower the salt content in the surface layer of the soil, the germination rate of suaeda heteroptera with different kinds of sowing density is also increased by 6.8-34 times, the utilization rate of seeds of suaeda heteroptera is greatly increased, and the cost for an enterprise to buy the seeds to carry out ecological repair is lowered. Data of the temperature, the humidity, the conductivity and the like of multiple groups of experimental fields is measured and compared, after the soilis turned, it is found that physical and chemical properties of the soil are obviously changed, factors, which influence the growth of suaeda heteroptera, like the conductivity (an EC value) and the salinity, of the surface layer soil are all obviously lowered, the deep tillage makes the conductivity of the surface layer soil lowered by 24.86%, and after the deep tillage, the quantity of caves ofHelice tridens tientsinensis is lowered by 12.5%.

Description

technical field [0001] The invention relates to a red beach wetland saline-alkali Suaeda salsa ecological restoration method. Background technique [0002] The coastal area is the junction area where the land and the ocean interact, and it is the area with the most potential and vitality for the prosperity and development of human society. The coastal zone has not only great ecological benefits, but also great economic benefits. However, due to the continuous population agglomeration to the coastal zone, the pressure on the coastal zone is increasing, and resource and environmental problems are becoming more and more serious. The Shuangtaizi estuary in Liaoning is a typical coastal wetland ecosystem in northern my country. However, in recent years, with the development of the economy, human activities have increasingly disturbed the original red beach ecosystem, causing serious degradation of the original red beach ecosystem. Research and development of artificial restoratio...

Problems solved by technology

With the development of the economy, the ecological protection situation of coastal wetlands is severe: coastal wetlands have been eroded to varying degrees, destroying the original ecological community structure of wetlands, causing habitat destruction, loss of biodiversity and ecological imbalance, which seriously restricts wetland ecology The function of system service
