Embodiment 1

[0021] Embodiment 1: a kind of method of the present invention utilizes seedling-growing greenhouses to multiply Heterochromia in a large number, comprises the following steps:

[0022] a. Tobacco seeding: Tobacco seedlings are produced on a large scale using seedling raising materials in the seedling cultivation workshop. The sowing arrangement on the seedling raising floating tray with 9 rows and 17 columns and a total of 153 holes is 4 rows and 8 columns; , do not sow in rows and columns, 32 holes are sown in each plate, 4 rows and 8 columns;

[0023] b. Aphids inoculation: start to inoculate the tobacco seedlings at the three-leaf and one-heart stage, inoculate 3 senior-age aphids on each tobacco seedling, and inoculate 90 heads on each seedling tray; after one week, observe the growth of the aphis Carry out supplementary inoculation where the inoculation is unsuccessful;

[0024] c. Ladybug inoculation: 20 days of multiplication of aphids, when the number of aphids per p...

The sowing arrangement on the seedling raising floating tray with 9 rows and 17 columns and a total of 153 holes is 4 rows and 8 columns; , do not sow in rows and columns, 32 holes are sown in each plate, 4 rows and 8 columns;

[0030] b. Aphids inoculation: start to inoculate the tobacco seedlings at the three-leaf and one-heart stage, inoculate 3 senior-age aphids on each tobacco seedling, and inoculate 110 heads on each seedling tray; after one week, observe the growth of the aphis Carry out supplementary inoculation where the inoculation is unsuccessful;

[0031] c. Ladybug inoculation: 20 days of multiplication of aphids, and when the number of aphi...

Embodiment 3

[0035] Embodiment 3: a kind of method of the present invention utilizes seedling-growing greenhouses to proliferate Heterochromia in a large number, comprises the following steps:

[0036]a. Tobacco seeding: Tobacco seedlings are produced on a large scale using seedling raising materials in the seedling cultivation workshop. The sowing arrangement on the seedling raising floating tray with 9 rows and 17 columns and a total of 153 holes is 4 rows and 8 columns; , do not sow in rows and columns, 32 holes are sown in each plate, 4 rows and 8 columns;

[0037] b. Aphids inoculation: start to inoculate the tobacco seedlings at the three-leaf and one-heart stage, inoculate 3 senior-age aphids on each tobacco seedling, and inoculate 100 heads on each seedling tray; Carry out supplementary inoculation where the inoculation is unsuccessful;

[0038] c. Ladybug inoculation: 20 days of propagation of aphids, and when the number of aphids per plant is 200, start to inoculate the newly ha...

Abstract

The invention relates to a method of utilizing a seedling growing greenhouse to propagate harmonia axyridis in a large number. The method includes following steps: a, sowing tobacco; b, inoculating myzus persicae; c, inoculating ladybird; d, collecting the ladybird; e, refrigerating; f, performing daily management. Tobacco seedling growing greenhouse facility is utilized to realize large-scale production of tobacco seedlings, and breeding cost is lowered; the tobacco seedling growing greenhouse facility is utilized to meet temperature, humidity and light conditions and isolating conditions needed by myzus persicae and the ladybird, and death rate of myzus persicae and the ladybird is lowered; through collection and exposure of pupa to the sun, convenence in collection and storage of harmonia axyridis is realized, and transportation and storage death rate of the ladybird is lowered; through refrigerating the pupa, large-number storage, all-time transportation and all-time release of harmonia axyridis and lowering of storage cost can be realized.

Description

technical field [0001] The invention relates to a method for multiplying the heterochromia ladybug in large quantities in a seedling-raising greenhouse. Background technique [0002] The artificial breeding of Heterochromia needs a large amount of live food (such as aphid), and the breeding of aphid live food needs to plant a large number of host plants (such as tobacco leaves), but the growth of aphids is dependent on temperature, humidity and light. Stronger, aphid breeding is difficult, the cost is higher, the labor input is larger, and the technology is difficult. These are the main problems restricting the large-scale reproduction of Heterochromatia at this stage. Contents of the invention [0003] The present invention provides a method for multiplying the heterochromia in large quantities in a seedling-raising greenhouse. [0004] The present invention utilizes the method for a large number of multicolored ladybugs to multiply in a seedling-growing greenhouse, whic...
