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

Embodiment 1

[0068] A kind of method that adopts ryegrass establishment to regulate the diversity of insect community in airport, carries out according to the following steps:

[0069] (1) Choose perennial ryegrass ( Lolium perenne L . ) to establish a single lawn for the test plants. Four experimental areas were randomly selected at the airport. grow naturally and without mowing;

[0070] (2) The main mowing area is rolled twice a year, and the vegetation is mowed every half a month;

[0071] (3) Dig the soil in the ryegrass lawn test area and sow ryegrass seeds. The total sowing amount is 10 kg, and 50 furrows are reclaimed. The distance between each furrow is 0.3 m, and the seeding amount in each furrow is about 0.2 kg;

[0072] (4) A quadrat with an area of ​​1 m × 1 m was randomly selected in each plot, and insects were collected by net catching and free-hand catching. Each net catching was done by the same person, and the diameter of the insect net was 30 cm with the same intensi...

Abstract

The invention discloses a method for regulating airport insect community diversity by adopting lolium perenne planting. The method comprises the steps that firstly, lolium perenne and festuca elata are selected as test plants for single lawn planting, four test areas are randomly selected at an airport, the size of each area is 15m*20m, the middle interval is 2m, ripping is carried out with a rooter, grass seeds are not sown to make vegetation grow naturally, and clipping is not carried out; a main clipping area is grinded twice each year, clipping treatment once is carried out on the vegetation each half month; ripping is carried out in the lolium perenne lawn test area, the lolium perenne seeds are sown, the total seeding quantity is 10 kilograms, 50 ditches are dug up, an interval of each ditch is 0.3 meter, and seeding quantity of each ditch is 0.2 kilogram; the quantity of insects is randomly recorded in each sample area, later, the collected insects are taken back to a laboratoryfor sorting and identification. According to the method for regulating the airport insect community diversity by adopting the lolium perenne planting, lawn plant lolium perenne not growing in an original habitat is planted at the airport. The invention aims at exploring the effect of single lawn plants on the insect community and diversity of 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 ryegrass establishment. Background technique [0002] Herbivorous insects and plants are a process of co-coordinated evolution. During the long evolutionary process, complex interactions have been formed among plants, herbivorous insects and their natural enemies. On the one hand, plants have a direct defense response after being fed by insects; on the other hand, insects also resist or adapt to plant defenses in various ways; in addition, after pests damage plants, they will also produce volatile substances Attract natural enemies and indirectly defend against pests. Studies have shown that the establishment of exotic plants can have a certain impact on native herbivores. Compared with native plants, the introduction of exotic plants can reduce the attractiveness to insects and reduce th...
