Embodiment 1

[0068] In the degraded light beach area of ​​Suaeda salsa in Panjin Red Beach, the soil conductivity of the saline-alkali land is 10ms / cm, which is characterized by coastal wetlands, which are flooded by tidal water regularly every day, and the soil particles are dense with a density of 1.7g / cm 3 , the silt with a soil particle size below 0.1mm accounts for 73%. From March to April, the soil conditioner is applied to the smooth beach area. The soil conditioner is made of the following raw materials: (urea (7.5kg / mu), ammonium dihydrogen phosphate (3kg / mu), humic acid 3kg / mu, Scallop shell powder 80kg / mu, reed straw powder fermented by Bacillus subtilis and yeast 60kg / mu), cooperate with mechanical or manual methods to plow the land to a depth of 20-30cm, level the land, and Blocks are crushed and leveled. Wherein, the fermenting process of the reed straw powder is as follows: 1000kg of reed straw is pulverized with a pulverizer until the length is less than 2mm, watered thoro...

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...
