Problems solved by technology

The natural plant buffer zone is the result of natural succession and maintains the germplasm resources of agricultural organisms. However, the vegetation in the natural plant buffer zone is mixed, and there are many vicious weeds and winter / summer hosts of pests. Its function in serving the production of agricultural and forestry crops is not good.

Embodiment 1

[0025] Example 1: The preferred combination of flowers and plants

[0026] In terms of mass percentage, the preferred flower and herb combination plant species include: 35% tall fescue, 10% foxtail grass, 15% red clover, 10% mung bean, 5% chrysanthemum, and 5% chamomile , 5% caraway from Umbelliferae, 5% winter rapeseed from Cruciferae, 5% sage from Lamiaceae, and 5% borage from Borageaceae.

Embodiment 2

[0027] Embodiment 2: Conservation and regulation of mulberry orchard organisms by artificial plant buffer zone

[0028] Three test points were selected in the intensive mulberry contiguous planting area in Shaanxi, 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 mulberry garden with a plant buffer zone built between the rows of mulberry trees with the preferred combination of flowers and plants. The control plot refers to the mulberry garden under normal intensive management, and the use of herbicides and insecticides is prohibited in the treatment plot. During the four growing seasons of mulberry trees, mechanical flukes and surface traps were used to collect arthropod specimens in the sample plots, to identify arthropod species, and to count the number of each type. During the investigatio...

Abstract

The invention discloses a flower and grass combination for increasing natural enemies to control pests in a mulberry field and application. The flower and grass combination covers herbs of seven families and ten species, the plants are diversified, and are of tough vitality, management and protection are simple, and morphological structures of the plants match ecological functions of the plants scientifically and reasonably. The flower and grass combination is used for building an artificial plant buffering strip in the mulberry field, growth of worst weeds can be inhibited, a thriving place of microfaunas and meiofaunas is reconstructed in the mulberry field, the kinds of biological species are enriched, the individual number of the biological species is increased, the multiple kinds of natural enemies are cultured, the pests are expelled from the mulberry field or the natural enemies are released to take initiative to prey on the pests on mulberry trees and to be parasitic on the pests on the mulberry trees, the pests in various stages of the mulberry field are controlled continuously, intensive withdrawal or less application of herbicides and pesticides in the mulberry field isachieved, green efficient sustainable development of the mulberry planting industry is supported, the quality safety of mulberry fruit products or silkworm feed is ensured, and mulberry field production and rural human habitat environments are beautified.

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 mulberry field and its application. Background technique [0002] The leaves of mulberry are feed for silkworms, the wood can be used to make utensils, the branches can be used to weave baskets, the mulberry bark can be used as raw material for papermaking, the mulberry fruit can be used for food and wine making, and the leaves, fruits and root bark can be used as medicine. It is an important economic forest tree. Mulberry originates in China, and is cultivated in all provinces and regions from the northeast to the southwest, from the northwest to Xinjiang, and is also cultivated in Northeast Asia, Central Asia, South Asia, Europe and other places. The main pests in mulberry gardens are mulberry caterpillars, mulberry weevils, mulberry thrips, etc., which cause a 30-40% ...
