However, there are also some problems in the work of bee breeding, such as the time overlap between flue-cured tobacco bee breeding and agricultural bee breeding, and conflicts in the use of facilities. In addition, because the area of large agricultural crops is much larger than the area of flue-cured tobacco planting, the original matching flue-cured tobacco The facilities cannot meet the needs of large agricultural crops, and the original technical facilities occupy a large amount of facilities, complicated management, high cost and low agricultural supporting funds, etc.

Embodiment 1
[0022] Embodiment 1 (in the base, utilize regenerated tobacco strains to proliferate agricultural breeding bees with aphids and bees)
[0023] From May 15 to July 22, 2016, the effect of the present invention on breeding aphids and bees was verified experimentally at the Yunnan Tobacco Company Honghezhou Company's Xinshao Triangle Land Aphids aphids breeding base. The experimental procedures and investigation results are as follows:
[0024] Breeding Regenerated Tobacco Strains
[0025] On May 15, 2016, after the second-grade species of aphid tobacco plants used by the flue-cured tobacco breeding base of the triangular terrestrial beetle were used, the tobacco stems were cut obliquely with a sterilized sickle, leaving a short pile with a 20cm oblique opening. After treatment, use 500 times Dongwang antiseptic to smear the incision to prevent rot, etc., and spray imidacloprid insecticide once. After treatment, 30g of compound fertilizer per plant was applied dryly, and then c...
Embodiment 2
[0036] Embodiment 2 (utilize regeneration tobacco strain to carry out multiply aphid, multiply bee in field)
[0037] From July 15th to November 10th, 2016, the present invention was verified experimentally at the olive slope base of Honghezhou Company, Yunnan Tobacco Company. The experimental procedures and investigation results are as follows:
[0038] Breeding Regenerated Tobacco Strains
[0039]On July 15, 2016, after the flue-cured tobacco was harvested at the olive slope base, the tobacco stems were cut obliquely with a sterilized sickle, leaving 20cm short piles. Each point is selected in three side-by-side tobacco plants, and 10 plants are treated for each plant, and a total of 30 plants are treated. After the treatment, 500 times of Dongwang disinfectant is applied to the incision to prevent rot and so on. After treatment, 30g of compound fertilizer per plant was applied dryly, and then covered with soil, and then watered with 5‰ ammonium nitrate aqueous solution to...

Abstract
The invention discloses a myzus persicae and myzus persicae braconid reproduction method of reproduced tobacco plants. The method includes the steps of when first-time aphid and braconid reproduction is finished or field tobacco leaf harvest is finished, cutting off stems, over 20-25 cm above the ground, of the tobacco plants without diseases and insect pests, loosening and ridging the soil, applying fertilizers, making the tobacco plants grow for the second time, reserving one robust lateral bud in sprouted new buds to continue cultivation, and clearing away the rest of the lateral buds; when each reproduced tobacco plant has 7-9 new leaves, inoculating the lower middle part of each tobacco leaf with aphids, covering an insect proof net after aphid inoculation, and inoculating braconid after aphid reproduction. According to the method, no seedling culture and transplanting are needed, and a greenhouse or other infrastructures do not need to be constructed or occupied, so that the inoculating aphid or inoculating braconid tobacco plants used for flue-cured tobacco braconid reproduction can be directly cultivated to be the reproduced tobacco plants for second-time reproduction of inoculating aphids and inoculating braconids. Meanwhile, according to the method, reproduced tobacco plant braconid reproduction can be directly conducted in the field, the cover net is opened after braconid reproduction, and adult braconids are allowed to spread freely to increase the amount of the braconids in the field and improve the control effect on aphids in the field.
Description
technical field [0001] The invention belongs to the technical field of breeding aphids and aphids, in particular to a method for regenerating tobacco plants to reproduce aphids and aphids. Background technique [0002] The technology of controlling aphids by using Aphids aphids has been relatively mature in the application of flue-cured tobacco, with remarkable economic and ecological benefits, and has been widely applied in flue-cured tobacco in Yunnan Province. Because Aphids aphids can not only parasitize peach aphids, but also parasitize radish aphids Lipaph is erysimi, wheat long tube aphids Macrosiphum avenae, wheat aphids Schizaphis graminum and other aphids. In recent years, tobacco companies in various cities in Yunnan Province have joined forces with the agricultural departments to try to promote the application of Aphids persicae in agriculture and have achieved certain results. However, there are also some problems in the bee breeding work. For example, flue-cur...
