Embodiment Construction

[0029] The present invention uses the concrete method steps of the method for eliminating the biological control method of aphids as follows:

[0030] 1. Planting radish planting

[0031] 1.1 Transplanting: Use pots as the carrier for planting radish;

[0032] 1.2 Preparation of nutrient soil: 7 days before transplanting, mix evenly 25% of livestock manure, 70% of paddy field soil, 4.5% of oil dryness and 0.5% of compound fertilizer, and put the prepared nutrient soil into the pot The layout is standardized and neat, and the ratio of N\P\K in the compound fertilizer is 8:16:25;

[0033] 1.3 Cultivation methods: live broadcast or transplant 2 radish seedlings with 4 leaves and 2 hearts in pots. Radishes like cool and humid climate conditions, avoid high temperature, strong cold resistance, weak heat resistance, and the suitable growth temperature is 15°C or 20°C. ℃, light frost will not wither, radish has strong fertility resistance, and requires a large amount of fertilizer....

Abstract

The invention discloses a biological preventing and controlling method for eliminating aphids and belongs to the technical field of biological prevention and control. The method comprises the steps of radish planting, aphid inoculating reproduction, diaeretiella rapae inoculating reproduction, management, disinfection and purification and rejuvenation in the breeding process of the aphids and the diaeretiella rapae and large-scale breeding. The biological preventing and controlling method has the advantages that radish with large blade space and small humidity serves as a host plant material for hosting the aphids, mildew infection in the breeding process of the breeding aphids and the breeding diaeretiella rapae is avoided, and when the aphids and the diaeretiella rapae are inoculated, operation is convenient and flexible, and management is easy; the bred aphids and the bred diaeretiella rapae are strong and large, the migratory flight rate of the aphids is low, and the birth rate of the aphids and the diaeretiella rapae is high; it can be guaranteed that the number and the quality of the breeding aphids and the breeding diaeretiella rapae are high; according to the biological preventing and controlling method for eliminating the aphids, the production cost is low, operation is easy and convenient, safety is achieved, no viral infection is caused, and large-scale breeding and popularization of the diaeretiella rapae can be achieved conveniently.

Description

technical field [0001] The invention relates to a biological control method for eliminating aphids, belonging to the technical field of biological control. Background technique [0002] Aphids aphidalis is a parasitic wasp, which is a natural enemy of aphids (pests) that damage various crops. The application of Aphidus venarii to control aphids can greatly reduce the amount of pesticides and improve the safety of agricultural products. At present, it has been widely promoted and applied on tobacco. The cultivation of Aphidus vegeta must first plant the host plants of the aphids, let the host plants of the aphids grow, and then inoculate the aphids on the host plants to make the aphids reproduce. After the aphids have reproduced, they are inoculated with Aphidida venarii. Aphidia venaridis feeds on aphids and parasitizes in the aphids by laying eggs. It reproduces its own population through aphids and achieves the purpose of eliminating aphids. [0003] The method of eradi...
