Embodiment 1

[0086] A control method of sludge filling matrix on bacterial diversity in airport soil:

[0087] (1) First, mow the vegetation in the control area, and then plow the area to a depth of 20 cm, plowing once;

[0088] (2) In the experimental area of ​​the control area, 250 t / ha of fly ash was sprinkled in the control area and mixed evenly with the overturned soil for every 6.7 m×5 m sample plot. After filling, the vegetation in the control area was in a natural growth state. state;

[0089] (3) After filling the regulating matrix, soil samples were collected in the matrix regulating area in the autumn of the same year, spring of the following year, and summer of the following year for measurement. Wherein said collection soil sample is measured and refers to: before collecting, remove the weeds of soil surface layer, adopt S type sampling method, select 20 sampling points at random in each test plot, drill the topsoil of 10cm depth with soil auger, Pick out the large root syst...

Abstract

The invention discloses a method for regulating and controlling the diversity of bacteria in airport soil by using sludge filling matrix. Firstly, the vegetation in the regulation and control area iscut, then soil turning is carried out on the area, the depth is 20 cm, and plowing is carried out once; in each 6.7m * 5 m sample field, 250 t / ha of fly ash is spread in the regulation and control area and is uniformly mixed with the turned soil, and the vegetation in the filled regulation and control area is in a natural growth state; after the filling of the regulating and controlling matrix isfinished, a soil sample is collected in the matrix regulation and control area and determined in the autumn in the same year and in the spring and summer in the next year. The invention aims to provide a theoretical basis for effectively regulating and controlling the overground vegetation community structure and the insect number characteristic so as to reduce the bird food source or cut off thebird food chain to achieve the purpose of ecological bird management in the airport, and basis ecological data is accumulated for bird strike prevention and control by using an ecological method in the airport.

Description

technical field [0001] The invention belongs to the technical field of ecological safety, and relates to a method for reducing bacterial diversity in airport soil by filling a sludge substrate. Background technique [0002] Soil bacteria are an important component of the soil ecosystem, play an important role in the process of material and energy transfer in the soil ecosystem, and indirectly affect the growth and development of aboveground plants. First of all, soil bacteria play an important role in soil fertility: they can decompose insoluble minerals in the soil into soluble mineral elements, and release nutrients that are beneficial to plants; through metabolism, they affect the transformation and flow of elements. For example, soil bacteria can Decompose the dead litter of plants, and affect plant growth and community composition by controlling the absorbable nutrients in the soil; soil bacteria themselves contain a certain amount of C, N, P, S and other elements, whic...
