Problems solved by technology

[0003] However, the traditional breeding of aphids is a highly technical job with high requirements on the quality of management personnel, nutrient supply level, environmental temperature and humidity, etc.
This method usually needs to choose the right time, and through multiple inoculations and even inoculations, the aphids can be reproduced better. However, the reproduction speed of the aphid is still very slow, and the individual of the aphid is thin and often very uneven.
If breeding bees in a large field, special isolation measures such as insect-proof net structure are also required. This isolation measure requires the purchase of raw materials and special care

Embodiment 1

[0057] A field rapid propagation method of aphids aphids, comprising the following steps:

[0058] 1) Location selection: choose an area with a higher terrain, and the terrain is in the "upwind" position of the main wind direction of the season, and the soil fertility is above medium, so as to facilitate the migration or expand the migration range of Aphids aphidatidis;

[0059] 2) Selection of host crops for aphid inoculation: choose tobacco as host crop for aphid inoculation;

[0060] 3) Spatial layout: One breeding point is set up for every 30 mu of prevention and control area, and each breeding point cultivates 30m of host crops 2 carry out spatial layout;

[0061] 4) Time selection: 15 days before the transplanting or sowing of the spring crops to be cultivated in the prevention and control area, start to cultivate the aphid host crops;

[0062] 5) Cultivation measures:

[0063] A, plant row spacing: the cultivation row spacing is carried out with 0.8m to open moisture...

Embodiment 2

[0074] A field rapid propagation method of aphids aphids, comprising the following steps:

[0075] 1) Location selection: choose an area with a higher terrain, and the terrain is in the "upwind" position of the main wind direction of the season, and the soil fertility is above medium, so as to facilitate the migration or expand the migration range of Aphids aphidatidis;

[0076] 2) Selection of host crops for aphids: select vegetables as host crops for aphids;

[0077] 3) Spatial layout: One breeding point is set up for every 50 mu of prevention and control area, and each breeding point cultivates 40 m of host crops 2 carry out spatial layout;

[0078] 4) Time selection: 20 days before the transplanting or sowing of the spring crops to be cultivated in the prevention and control area, start to cultivate the aphid host crops;

[0079] 5) Cultivation measures:

[0080] A, plant row spacing: the cultivation row spacing is carried out with 1.2m to open moisture, open 4 rows, t...

Embodiment 3

[0091] A field rapid propagation method of aphids aphids, comprising the following steps:

[0092] 1) Location selection: choose an area with a higher terrain, and the terrain is in the "upwind" position of the main wind direction of the prevention and control season, and the soil fertility is above medium, so as to facilitate the migration or expand the migration range of Aphids aphididae; The standards for soil fertility above medium are: soil organic matter ≥ 2%, soil alkaline nitrogen ≥ 80mg / kg, soil available phosphorus ≥ 20mg / kg, soil available potassium ≥ 120mg / kg, soil magnesium ≥ 50mg / kg, boron, zinc , molybdenum, manganese and other trace elements require ≥0.10mg / kg, chloride ion content ≤45mg / kg;

[0093] 2) Selection of host crops for inoculation with aphids: select tobacco as the host crop for inoculation with aphids; said tobacco is a virus-resistant tobacco variety, specifically NC102;

[0094] 3) Spatial layout: One breeding point is set up for every 35 mu of ...

Abstract

The invention discloses a rapid field breeding method of aphidius gifuensis. The breeding method comprises the following steps of place selection, aphid inoculation host crop selection, space layout, time selection, cultivation measures, aphid breed inoculation, bee breed inoculation and post-processing. The problem that technical requirements of traditional aphidius gifuensis breeding are high is effectively solved, a good parasitism place is provided for aphidius gifuensis breeding, the middle links of inoculation are greatly simplified, the uniformity requirements of inoculation are reduced, the aphidius gifuensis breeding speed can be also multiplied, individual development is good, accordingly the artificial aphidius gifuensis breeding efficiency is greatly improved, and the labor and material costs are reduced.

Description

technical field [0001] The invention belongs to the technical field of tobacco pest prevention and control, and in particular relates to a field rapid propagation method of Aphids persicae. Background technique [0002] Myzus persicae (Sulzer), also known as Myzus persicae (Sulzer), is a common pest that harms Solanaceae (such as tobacco, eggplant) and Rosaceae (such as peach trees). At present, the best way to prevent and control aphids is to artificially reproduce a large number of healthy aphids, and then let a small amount of Aphids aphids parasitize on these aphids, and these parasitized aphids become inactive The dead aphid, that is, the "semi-finished product" of the Aphidia persicae, is released in batches into the tobacco field and the large agricultural environment, and soon hatches into the A. purpose of pests. [0003] However, the traditional breeding of aphids is a highly technical job that requires high quality of management personnel, nutrient supply level,...
