Method for regulating and controlling diversity of insect communities in airport by adopting festuca arundinacea establishment

Abstract

The invention discloses a method for regulating and controlling the diversity of insect communities in an airport by adopting festuca arundinacea establishment. The method comprises the following steps: selecting perennial festuca arundinacea as a test plant for establishment of a single turf, randomly selecting four test plots in the airport, wherein each test plot has a size of 15 m x 20 m and an intervening interval of 2 m, turning soil with a soil turning machine, and allowing a vegetation to naturally grow, wherein no festuca arundinacea seeds are spread, and no cutting is performed; carrying out rolling compaction twice every year for a main cutting area, and cutting the vegetation once every half month; turning the soil in a festuca arundinacea turf test plot, then sowing festuca arundinacea seeds with a total sowing amount of 10 kg, and digging 50 ditches with a separation distance of 0.3 m, wherein the sowing amount of the festuca arundinacea seeds in each ditch is about 0.2 kg; and randomly recording the number of insects in each sample plot, and taking collected insects back to a laboratory for sorting and identification. The method provided by the invention aims to research the influence of a single turf plant on an insect community and the diversity of the insect communities in the airport mainly through establishment of non-native turf plant namely festuca arundinacea in the airport.

Description

technical field [0001] The invention belongs to the technical field of ecological security, and relates to a method for regulating the diversity of insect communities in airports by using tall fescue planting. Background technique [0002] Insect ecology is a science that takes insects as the research object and studies the relationship between insects and their surrounding environment. The development of many ecological theories depends on insect ecology, and the development of ecological theories promotes the development of insect ecology. Moreover, insect ecology is a highly practical subject and is the basis for guiding pest management. In recent years, as the research on insect ecology has been paid more and more attention by scientists, there have been great developments mainly in insect molecular ecology, insect chemical ecology, insect behavior ecology, insect information ecology and insect population ecology. . [0003] Herbivorous insects and plants are a proces...

Problems solved by technology

At present, more traditional pest control techniques are generally adopted in the world, such as spraying pesticides, chemical reagents, or artificial mowing. Although it has a certain effect on reducing the number of insects to a certain extent, this practice seriously pollutes the airport. Soil, water and other environments, and time-consuming and money-consuming, plus a long time, some insects are resistant to pesticides, it is difficult to eliminate
