Bee Technology
1, the number of bee release: put three bees, the first time in the corn pupa rate of 13-15%, after 10 days to put the bee; interval 5 days after the second release; and then 10 days after the third release.
2. The number of bees released: The total amount of land per acre is 15,000 heads, and the first time is 0.5 million heads per acre. The second time, 0.5 million heads per mu. The third time, 0.5 million heads per mu.
3. Put the number of bees: Put two points per mu, each controlling 334 square meters.
4, put bee method:
(1), torn bee card: According to the number of bees put the big bee card torn into small pieces, each parasitic egg about 80-100 bees, two pieces per acre.
(2) Set the bee point: Set two bees for each acre, and place the two bees on one acre. Calculated at 67 centimeters per ridge width, starting from the upper bunker, the bee-keeper began counting the number of ridges in the bee field. The 9th ridge was the first one to be placed in the ridge, and the first ridge was placed in the direction from the top of the ridge. 14 Rice is the first place to put the bee, and the first place of bee-feeding begins to go further 28 meters for the second place of the bee, and the second place for the bee begins to go forward 28 meters for the third place. The bees, after which every 28 meters is a bee, and so on. From the first ridge of the first bee ridge, the second ridge was placed on the 18th ridge, and on the second ridge, it was also the first burial point that was 14 meters from the ground. In the first place, the bees begin to advance another 28 meters for the second bee, in the second bee point, another 28 meters for the third bee, and every 28 meters thereafter. For a bee, and so on to the ground. The following burial ridges all count down to the next ridge of the previous bee ridge. The 18th ridge is the next ridge, and the ridge is placed in the same position as the first rinsing ridge. On the other side of the ridge, if the ridge is less than 9 ridges, then the ridge is the last one, if the ridge is more than 9 ridges and less than 18 ridges, According to the specific circumstances, appropriate amounts of bees are placed on the appropriate ridges, and specific analysis is appropriate.
(3) Putting the bee on the bee: After picking a bee, pick a corn with healthy growth, pick a leaf in the middle of the plant, tear it in half along the main vein, take half of it and put the bee card in the direction of the stem. Gently roll up into a tube, with the parasite egg facing downward (ie, with the bee facing downwards), and then secure it with mats or threads.
Precautions:
(1) After the farmer receives the bee card, it must be released on the morning of the same day. In the event of light rain, it can be released. In the unlikely event of heavy rain, the bees can be stored temporarily. Choose a cool, well-ventilated warehouse. Distribute the bee cards. Do not put them together with pesticides.
(2) You can tear the bee card by hand and you cannot use scissors. The eggs that were dropped when tearing the bee card were collected and glued onto the white paper.
(3) When hanging the card, the blades must not be rolled too tight so as not to affect the bees. It must not be placed in the leaves of the corn or be placed on the leaves in order to avoid the failure of the bee card.
(4) After the bee-card is hung in the field, the bee is gradually released after 2-3 days, and a round feathering hole is visible on the egg shell of the bee.
(5) Do not use pins, toothpicks, etc. to prevent bovine stomach damage during corn harvesting or harvesting, resulting in accidents.
(6) When releasing, set the position according to the wind direction and the wind speed. If the wind is large, increase the number of points or release volume in the upper winds, and reduce the downwinds appropriately.
(7) In the corn field where the bees were placed, 4 days before the bee was released, no pesticide was allowed within 20 days after the bee was released.
