Embodiment 1

[0105] A method for regulating the diversity of airport soil nematodes by sludge filling substrate:

[0106] (1) First, mow the vegetation in the control area, and then plough the soil in the area to a depth of 20 cm, and plough once;

[0107] (2) In the experimental area of ​​the control area, 250 t / ha fly ash was sprinkled in the control area and mixed with the turned soil at every 6.7 m × 5 m plot. After filling, the vegetation in the control area was in a natural growth state. state;

[0108] (3) After the filling of the regulated matrix was completed, soil samples were collected from the matrix regulated area in the autumn of the same year, the spring of the following year, and the summer of the following year, respectively. Wherein, the collection of soil samples for measurement refers to: before collection, remove the weeds on the soil surface layer, adopt the S-type sampling method, randomly select 20 sampling points in each experimental plot, and drill the surface so...

Abstract

The invention discloses a method for regulating and controlling the diversity of soil nematodes in an airport by using a sludge filled substrate. The method comprises the following steps: cutting vegetation in a regulation and control area, then turning soil for the area with a soil-turning depth of 20 cm, and carrying out ploughing for one time; then spreading sludge with an amount of 250 t/ha into the regulation and control area according to an area of 6.7 m x 5 m per sample plot, uniformly mixing the sludge with the turned soil, and after completion of filling, allowing the vegetation in the regulation and control area to be in a natural growth state; and after filling of a regulation and control substrate is completed, respectively acquiring soil samples in a substrate regulated and controlled area in the autumn of the same year and the spring and summer of the next year, and carrying out determining. The method provided by the invention aims to provide a theoretical basis for achieving the purpose of airport ecological bird control by reducing a bird food source or cutting off a bird food chain through effective regulation and control of the above-ground vegetation community structure and insect number characteristics, and accumulates basic ecological information for preventing and controlling bird strike for the airport by applying an ecological method.

Description

technical field [0001] The invention belongs to the technical field of ecological safety, and relates to the regulation of nematode diversity in airport soil by a sludge filling matrix. Background technique [0002] Soil organisms are divided into two categories: soil microorganisms and soil animals. There are bacteria, fungi and actinomycetes in the microorganisms. Soil animals can be divided into protists (such as flagellates and ciliates, etc.) and wet small soil animals ( such as nematodes), small arthropods (such as ticks), and large soil animals (such as earthworms). Soil organisms play an important role in soil formation, maintaining ecosystem circulation, and waste decomposition, and are especially irreplaceable in nutrient cycling and litter decomposition, providing ecosystem services such as climate regulation, carbon sequestration, driving material circulation, and even a Soil organisms can play a decisive role in the entire soil ecosystem. Soil organisms are se...
