Bumblebee pollination technology is applied to the cultivation of facilities for vegetables, which can save time and labor, improve fruit set and fruit quality, increase vegetable yield, reduce hormone residues, help tomatoes and other vegetables with special odor for insecticide pollination, and solve the problem The problem of pollination under relatively isolated conditions also meets the safety, green, and organic planting requirements, which greatly improves the quality of the vegetables. At present, the bumblebee pollination technology has been demonstrated in the cultivation of tomato, pepper, eggplant, strawberry, and watermelon. Bumblebee pollination technology should pay attention to the following points in practical applications:
First, the purchase of bumblebees. At present, China has already broken through the annual artificial breeding technology of the bumblebee. Producers can choose to buy local bumblebees with strong adaptability to local natural conditions. This can prevent bumblebees from growing slowly due to environmental discomfort and failing to complete pollination work. Such phenomena.
Second, before the preparation of bees. The bumblebee pollinated vegetable facilities should be covered with insect nets at the air outlet to prevent bumblebees from fleeing; the temperature in the facility should be controlled at 10-30°C and the humidity should be controlled at 50-90%. The temperature and humidity range is not only suitable for pollination but also ensured Bumblebee vitality; vegetable facilities before the introduction of bumblebees banned highly toxic, high residue, high absorption of pesticides, vegetables used pesticide facilities, should be placed in the hives after safe intervals.
Third, put the number and time of bees. Bumblebees are counted in groups. Each box of bumblebees is a group (80-100 heads). Generally, a box of bumble bees per acre can be obtained for crops with short flowering duration and easy access to flowers (such as cucumbers, watermelons, pumpkins, etc.), for tomatoes and peppers. Eggplants with long flowering periods, difficult pollen collection, and odor-stable vegetables can be placed in two boxes of bumblebees per acre. Generally when the vegetables bloom more than 5%, they can be placed into the bumblebee. The bumblebee should minimize the vibration when moving, to prevent the bee colony from being frightened. It is advisable to enter the shed in the evening, and the stable beehive should be left standing for at least 1 hour. Open the nest door.
Fourth, put the bee position. Bumblebees should be placed in the beehive more than 50cm above the ground, where vibration is unlikely to occur. Attention should be paid to sun protection, moisture protection, rodent control, and ant prevention. If it is necessary to change the position of the beehive, it should be carried out after dark to avoid the bumblebees from ignoring the nest.
Fifth, bee colony management. Currently, most of the bumblebees in the bee are equipped with sufficient feed for the bees to work throughout the flowering period in the hive. There is no need to feed them any more. For vegetables with less pollen, the bumblebees can be given rewarded feeding during pollination. 50% of the sugar water is placed in a wide-mouthed shallow dish for the bumblebee to feed, and a number of stones and wood pieces are placed in the shallow pan for the bumblebee to feed; the bumblebee is easily frightened. Apart from daily cleaning, try not to open the beehive or Tap the beehive, do not use pungent perfumes and cosmetics when touching the beehive to prevent the bees from snarling.
