Vega puts being actually needed for honeybee.
Technical scheme is as follows：A kind of method for breeding aphidius gifuensis using remaining floating tobacco seedlings, its feature exists
In the described method comprises the following steps：
Step (1) recovers remaining floating tobacco seedling growth：Remaining floating tobacco seedlings after flue-cured tobacco transplanting are focused on into numerous honeybee base,
The nursery pond vacated after flue-cured tobacco transplanting topdresses cultivation, to recover remaining floating tobacco seedling growth；
The transplanting of step (2) tobacco seedlings, leaf-cutting：Tobacco seedlings after restoration ecosystem are transplanted on new floating seedling tray, during transplanting
Seedling cave is filled up with new matrix, all old leafs in bottom are rejected, only retains 2, top leaf and lobus cardiacus, and carry out cultivation of topdressing, after transplanting
2, the top half of leaf is cut off immediately, promotes new leaf growth；
Step (3) connects aphid, numerous aphid：After tobacco seedlings grow 2 new films, kind of an aphid leaf is cut into or is torn into small pieces, it is uniform to dissipate
In tobacco seedlings, make have kind of an aphid leaf in every plant of tobacco seedlings as far as possible, tobacco seedlings are covered with fly net in time after connecing aphid, according to tobacco seedling growth shape
Condition carries out water and fertilizer management；
Step (4) connects honeybee, numerous honeybee：Connect honeybee, guard when average strain aphid amount reaches 150-200, be allowed to it is parasitic, numerous go out it is new
Aphidius gifuensis, water and fertilizer management is carried out according to tobacco seedling growth situation.
Further, normally disease-free, lobus cardiacus is normal completely, leaf green is disease-free by flue-cured tobacco transplanting back root part for step (1)
Harmful remaining floating tobacco seedlings focus on numerous honeybee base, prevent tobacco seedlings from damaging in transportation, the nursery vacated after flue-cured tobacco transplanting
Pond is topdressed cultivation, and remaining floating tobacco seedling growth was recovered through 3-5 days.
Further, step (2) by the density of 50 plants/disk (transplanting 1 row every 1 row), transplants the tobacco seedlings after restoration ecosystem
To length × width × height be 66.5cm × 34cm × 5.5cm, on the floating seedling tray of 100 cave specifications.
Further, kind of an aphid leaf is cut into or is torn into small pieces by step (3) after tobacco seedlings grow 2 young leaves, uniform to dissipate
