Problems solved by technology

In addition to parasitizing Aphids persicae, Aphis craccivora Koch also parasitizes Aphis craccivora Koch (on Vicia faba), an aphid of the genus Aphis sp. (on green vegetable Brassica chinensis), Capitophorus sp., radish aphid Lipaphis erysimi (Kaltenbach) , Macrosiphum sp. Myzus sp., Rhopalosiphum pseudobrassicae (Davis), Schizaphis graminum (Rondani), Sitobion akebiae (Shinji), S. ibarae (Matsumura), etc. Planting aphids is widely used in agriculture based on the characteristics of the wide range of hosts of A. It is mature and is currently in the stage of commercialization research and product promotion and application of Aphids persica. The release of bees in 10,000 mu of tobacco fields has achieved very good control effects. In the future, the commercialization of Aphids persicae is an inevitable trend, but the existing bee breeding sheds are limited, and there is overlap between flue-cured bee breeding and agricultural bee breeding cycles. The balance of supply and demand and the release time of Aphidius aphidatidis coincide with the demand time in the field. Shortening the breeding cycle as much as possible is an important way to solve these problems

Embodiment 1

[0030] Embodiment 1 Utilizes the floating tobacco seedlings to reproduce aphids and bees again after propagating and propagating aphids

[0031] According to the previous research results, from April to May 2016, the floating tobacco seedlings after the expansion of aphids were used to test the effects of aphids and bees again. The effects of each stage are as follows: Figure 1 to Figure 10 shown.

[0032] Cultivation of Regenerated Bleached Wet Tobacco Seedlings

[0033] Select robust floating tobacco seedlings that have been multiplied by aphids and have no diseases and insect pests. After cutting and utilizing the upper stems and leaves, keep the lower 8-10cm stems, remove the old roots and dip them in rooting powder, and transplant them to the specifications: length × width =54cm * 28cm, caliber 6cm, hole depth 10cm, 32 holes on the seedling tray, cover the root with moist new sandy soil, place in the nursery pool with compound fertilizer aqueous solution, the water dept...

Embodiment 2

[0044] Example 2 Using the floating smoke seedlings after the large-scale breeding of bees to multiply the bees again

[0045] Due to the short period for the propagation of aphids, it takes about 47 to 52 days from sowing seedlings to the end of the propagation of aphids. The aphid seedlings are relatively robust, and the utilization rate is above 95%. It takes about 65 to 70 days for large-scale bee breeding from sowing seedlings to the end of bee breeding. The growth of Aphid aphid seedlings is relatively weak. In 2016, the effect of using Aphid aphid seedlings to reproduce bees again was not good. From June to July 2017, on the basis of the success achieved in 2016, the floating smoke seedlings after large-scale breeding were used to test the effect of bee breeding again. The method was consistent with Example 1. Seedlings are used to multiply bees again, and the effect of breeding bees is equivalent to that of aphid seedlings, see Figure 10 .

Abstract

The invention discloses a method for utilizing regenerated floating tobacco seedlings to propagate myzus persicae and aphidius gifuensis ashmead. The method comprises the following steps that 1, robust floating tobacco seedlings are utilized after myzus persicae and aphidius gifuensis ashmead are propagated, stems and leaves at the upper portion are sheared and utilized, stalks 8-10 cm from the lower portion are reserved, old roots are removed, rooting powder is smeared, the stems and leaves are transplanted on seedling growing pit discs, an agent for preventing and controlling the root rot and tobacco virus diseases is sprayed, after a new bud is sprouted, one tobacco seedling robust in growth is reserved, and a dry and wet alternating method is adopted to conduct water and fertilizer management; 2, when the floating tobacco new leaves are regenerated, foliage fertilizer special for the tobacco is sprayed, one myzus persicae seedling is placed in the center of each seedling growing pit disc, myzus persicae is allowed to be independently spread to the surrounding, and propagating is conducted on the surrounding regenerated floating tobacco seedlings; 3, aphidius gifuensis ashmead is inoculated to be propagated; 4, aphidius gifuensis ashmead propagation management is conducted. According to the method for utilizing the regenerated floating tobacco seedlings to propagate myzus persicae and aphidius gifuensis ashmead, the remaining tobacco seedlings after collection of the flue-cured tobacco propagated aphidius gifuensis ashmead product is finished, waste is turned into wealth, myzus persicae and aphidius gifuensis ashmead are propagated, the requirements for tobacco field continuous aphidius gifuensis ashmead stocking and non-tobacco-farmer land stocking are met, and the method can be also applied to myzus persicae inoculation and aphidius gifuensis ashmead seedling reserving.

Description

technical field [0001] The invention belongs to the technical field of reproduction of aphids and aphids, in particular to a method for propagating aphids and aphids by using regenerated and bleached wet tobacco seedlings. Background technique [0002] In recent years, the technology of controlling Aphids aphids has been promoted and applied on a large scale across the country, and has been highly concerned and recognized by local governments and tobacco farmers, and has achieved remarkable ecological, economic and social benefits. In addition to parasitizing Aphids persicae, Aphis craccivora Koch also parasitizes Aphis craccivora Koch (on Vicia faba), an aphid of the genus Aphis sp. (on green vegetable Brassica chinensis), Capitophorus sp., radish aphid Lipaphis erysimi (Kaltenbach) , Macrosiphum sp. Myzus sp., Rhopalosiphum pseudobrassicae (Davis), Schizaphis graminum (Rondani), Sitobion akebiae (Shinji), S. ibarae (Matsumura), etc. Planting aphids is widely used in agric...
