Plant functional combination for planting in arenaceous fluctuating zone of reservoir area

Abstract

The invention relates to a plant functional combination for the planting in an arenaceous fluctuating zone of a reservoir area, which is characterized in that: acorus calamus seeds, a soil substrate, an organic fertilizer and a biological bonding agent are mixed and stirred in water uniformly according to a weight ratio of 1:(85-95):(5-10):(1.5-2.5), and 5 to 10 granules of the acorus calamus seeds are used as a sticky dumpling to obtain the plant functional combination, wherein the moisture content in the plant functional combination is between 40 and 65 percent, the content of N, P and organic matter in the organic fertilizer is between 10 and 20 g / kg, between 1 and 1.2 g / kg and between 35 and 60 g / kg respectively, and the biological bonding agent is prepared from starch, protein, dextrin and rosin in a ratio of (20-25):(5-10):(55-60):(10-15). The plant functional combination has the advantages that: the survival rate of plant seeds in the fluctuating zone is more than 30 percent; vegetation community of the arenaceous fluctuating zone of the reservoir area can be restored; and soil erosion is reduced.

Description

technical field [0001] The invention relates to a plant functional complex, in particular to a plant functional complex used for planting in sandy water-fluctuating zones in reservoir areas. Background technique [0002] The ebb and flow zone (also known as the ebb and flow zone or the ebb and flow zone) refers to a special area where the seasonal water level of the reservoir fluctuates and the surrounding submerged land is periodically exposed to the water surface. The last ecological barrier entering the water body has environmental functions such as intercepting and filtering sewage, improving water quality, controlling deposition and erosion, and at the same time has ecological functions such as maintaining biodiversity, providing fish breeding and bird habitats, and regulating and storing floods. Vegetation development in the water-fluctuation zone is crucial to the function of the water-fluctuation zone. [0003] At present, the planting in the sandy water-fluctuating...

Problems solved by technology

[0005] (2) The environmental conditions for the growth of plants in the water-fluctuating zone are relatively harsh, and they have to endure the stress of environmental factors such as flooding, strong light, drought, and nutrient deficiency. Difficulty screening;

[0006] (3) Due to the destruction of vegetation in the water-fluctuation zone, the soil structure in the water-fluctuation zone has been eroded by long-term water flow, resulting in serious water and soil loss in the reservoir area. The surface of the soil often contains a variety of rock fragments, with low clay content and high coarse powder content. Poor stability, not resistant to erosion, easy to be scoured, so it is difficult to establish a soil seed bank;

[0007] (4) The soil structure in the hydrofluctuation zone has been eroded by long-term water flow, and a large amount of soil organic matter has been dissolved into the water body, which not only causes the water quality in the reservoir area to deteriorate, but also due to the low soil organic matter, it is difficult for the selected pioneer species to obtain sufficient nutrition to continue their survival at the initial stage of settlement. Even if individual plants are successfully transplanted, it is difficult to form a stable vegetation community in the water-fluctuation zone
