Embodiment 1

[0024] Example 1: The preferred combination of flowers and plants

[0025] In terms of mass percentage, the preferred flower and grass combination plant species include: 30% Timothy Grass of Gramineae, 20% of Tall Fescue, 12% of White Clover of Leguminosae, 8% of Wild Alfalfa, 5% of Wild Buckwheat of Polygonaceae, Chrysanthemum 6% of chrysanthemum, 4% of spinach, 5% of plantain, and 10% of spring rape of crucifer.

Embodiment 2

[0026] Example 2: Conservation of biodiversity in farmland systems by artificial plant buffers

[0027] Three test points were selected in the intensive spring wheat contiguous planting area in the Hetao area, and the distance between the test points was greater than 1 km. Each test site is set up in pairs of treatment plots and control plots, and the distance between the two plots is greater than 200 meters. The treatment plot refers to the wheat field with the plant buffer zone built on the edge of the field with the preferred combination of flowers and plants (the part of the plant buffer zone is deducted), and the control plot refers to the wheat field without any changes in the normal intensive operation. During the wheat growing season, net and trap methods were used to collect arthropod specimens in the sample plots, to identify the types of pollinators and natural enemies, and to count the number of each type. During the investigation, the length of the net sweeping l...

Abstract

The invention discloses a flower and plant combination for increasing natural enemies and controlling pests in a spring wheat field and application. The flower and plant combination covers 9 kinds from 6 families, the number of plant varieties is moderate, the selected plants are wide in adaptability and high in stress tolerance, management and protection are simple, and the plant morphological structure and ecological function are scientifically and reasonably matched. The flower and plant combination is used for constructing an artificial plant buffer zone in a northern spring wheat field, can reconstruct the habitat of arthropods in a farmland system, increases the farmland biodiversity (species and abundance), protects pollination insects, improves the crop pollination effect, cultivates various natural enemies to control crop pests, and fixes nitrogen and carbon; soil health and environmental safety are promoted, dependence of intensive farmland on chemical fertilizers and pesticides is remarkably reduced, and green, efficient and sustainable development of agriculture and quality safety of agricultural products are supported; meanwhile, the farmland plant buffer zone is beneficial to improving the aesthetic effect of the rural ecological landscape.

Description

technical field [0001] The invention belongs to the technical field of farmland ecological enhancement, and relates to a combination of flowers and plants for increasing natural enemies to control pests in a spring wheat field and its application. Background technique [0002] Wheat is the main food crop in the world, and it is the second largest food crop after rice in China. Spring wheat is a type of wheat suitable for spring sowing and autumn harvest in cold northern regions. It is mainly harvested once a year. It is mainly distributed in the north of the Great Wall. The production areas include Heilongjiang, Inner Mongolia, Xinjiang, Gansu, Hebei, Tianjin and Ningxia. Wheat aphids are the most important pests of spring wheat. They suck the juice of wheat plants and secrete honeydew to cause mold growth. They also spread wheat virus diseases, seriously affecting the normal growth of wheat, resulting in reduced grain production and quality of agricultural products. Due to...
