Plant support systems for natural enemies of cabbage pests

Abstract

The invention relates to the field of crop pest bio-control and aims to provide a plant support system for cabbage pest natural enemies. The plant support system for the cabbage pest natural enemies comprises savings plants, nectariferous plants and trapping plants which are used to be planted in field blocks with cabbage, wherein the most peripheral field ridge in the field blocks is east west trend; the other middle field ridges are south north trend; the savings plants are planted on the peripheral east west trend field ridge of the field blocks; the nectariferous plants are planted on the peripheral south north trend field ridge of the field blocks; the trapping plants and the cabbage are planted on the middle south north trend field ridge of the field blocks planted with the nectariferous plants. According to the plant support system for the cabbage pest natural enemies provided by the invention, through establishing biological diversity, an eco-environment virtuous circle system is built, favorable inhibit conditions are created for the natural enemies, the capability of the natural enemies on controlling pests is enhanced, the natural enemies are utilized to control and replace chemical pesticides to use, pesticide residues of vegetables are avoided, the economic effect, the social effect and the ecological effect are achieved, and a solid foundation is established for building ecological agriculture.

Description

technical field [0001] The invention relates to the field of biological control of crop pests, in particular to a plant support system for natural enemies of cabbage pests. Background technique [0002] Cabbage (Brassica oleracea L.) is an annual or biennial herbaceous plant of the genus Brassica, and it is one of the important vegetables in my country. During the growth of cabbage, more than 20 kinds of pests are harmed, mainly including diamondback moth, cabbage caterpillar, whitefly and aphid, which seriously affect its yield and quality. [0003] In agricultural ecosystems, the growth of pest populations leads to the loss of crops, but at the same time its natural enemy factors will also restrict its excessive growth to a certain extent. The natural enemies of pests play an important role in the process of pest control, and how to increase the diversity and population of natural enemies as much as possible has become the focus of attention of all parties. It has become...
