With the development of agricultural modernization, fruits and vegetables and various horticultural cultivation are moving towards the direction of intensification and scale. These technologies have greatly improved the production efficiency, at the same time, guaranteed the stability of agricultural production and greatly improved the economic benefits. However, in the closed greenhouse, some special links also worry a large number of growers. For example, in the key planting link of crop pollination, the lack of wind pollination, insect pollination and bird pollination in the original nature has greatly restricted the production.

At present, farmers generally use artificial pollination to consume a large amount of labor. In order to promote the development of fruits, growth regulation hormones are often added during artificial pollination. Uneven pollination will increase the incidence of malformed fruits. At the same time, because of the improper use of growth regulators, crop growth or premature aging and other stunted growth problems. The use of chemicals without safety assessment will eventually lead consumers into a health and safety hazard.

High fruit setting rate is very important for crop production, and pollination is the key step of fruit setting. Bee pollination has long been considered the best way to pollinate crops in the field. Since the late 1980s, however, bumblebees have generally proved far more effective pollinators than bees in most environments. At present, the bumblebee is widely used in protected area with open pollination of crops, greenhouse vegetables and fruit trees pollination, it can not only improve crop yield, more important is can improve fruit quality, reduce the rate of deformity fruit, solve the problem such as hormone pollution brought by the applied chemistry pollination, therefore, bumblebee become the ideal of greenhouse vegetables pollination insects, using bumblebees pollination also to become the world recognized green food production is an important measure.

What are the characteristics of bumblebees?

1. Annual breeding: the diapause period of the queen bee can be shortened or broken under artificial control conditions, and the bumblebee pollination group can be bred according to the pollination needs of greenhouse vegetables in any season, thus solving the problem of applying insect pollination to greenhouse vegetables in winter.

2. Bumblebee has a long mouth organ (kiss): its kiss is 9-17 mm long, so for some vegetables with deep crown flowers, such as tomatoes, peppers, eggplants, etc., bumblebee pollination effect is more significant.

3. Strong collection force: bumblebees have large individuals, long life span, and are covered with fluff all over the body. They can fly over 5 kilometers and make more efficient use of the dense powder source than other bees.

4. Low temperature and low light tolerance: bumblebees can still collect pollination outside the nest in low temperature and low light environment. The annual pollination of greenhouse crops, especially in winter, can be realized by utilizing the biological characteristics of bumblebee in low temperature tolerance.

Poor phototaxis: in a greenhouse, bumblebees don't fly up into the glass like bees do, but rather meekly collect flowers.

6. Strong moisture resistance: bumblebees are relatively adaptable in the greenhouse with high humidity.

Loud: the flowers of some plants release pollen only when they are vibrated by the buzz of insects, making bumblebees ideal pollinators for such crops as strawberries, tomatoes, and eggplants.

2. Advantages of bumblebee pollination:

1. Significant yield increase: pollination of greenhouse tomato, green pepper, eggplant, strawberry and other vegetables, yield increase effect of more than 30%.

2. Improve quality: bumblebee has strong pollination power and high pollination rate. After pollination, the individual size of the fruit is uniform and the shape of the fruit is good and there is no abnormal fruit.

Left: hormone spots - seedless, hollow, less juice, fibrous flesh margin

Right: bear peak pollination - moderate fruit type, full seeds and flesh, juice

3. Time-saving and labor saving: the pollination work is completed by bumblebees without any labor. Can complete the crop pollination work in time effectively, enhances the pollination efficiency.

4. Improve the ecological and environmental benefits: the use of bumblebee pollination will reduce the use of toxic pesticides, and increase the use of low-toxicity, high-efficiency and safe pesticides, and consciously emphasize the use of biological control technology; Bumblebee pollination replaces hormone pollination, reduces the pollution caused by hormone, improves the quality of fruits and vegetables, protects the ecological environment, and is beneficial to the health of consumers.

Three, how to place the hive:

1. Beehives should be placed where bumblebees and humans can easily see them.

2. Do not shake the hive during transportation, and make sure the hive is placed horizontally. Wait about 20 minutes for the bumblebee to calm down before opening the hive.

3. Beehives should be placed 0.5-1 meter away from the ground to avoid direct sunlight and rain. In winter, take care that the hive inlet and outlet are not blocked by crop leaves.

4. Keep the hive away from the co2 supply and prevent ants from entering the hive.

5. When the bumblebee flies for the first time, it must make sure that the ventilation Windows of the greenhouse are closed before opening the exit of the hive. Avoid bumblebees from flying out of the greenhouse during directional flight.

Iv. The best time for bumblebee pollination

After the first directional flight, bumblebees will begin pollinating crops immediately. Bumblebees are generally active in the morning and afternoon. Activity also depends on the flowering of the crop. Bumblebees in 8-28 ℃ temperature is active, but the highest efficiency in the 15 to 23 ℃.

5. Reasons for choosing colbert bumblebee:

KOPPERT B.V. is a world leader in crop pest control and bio-pollination. Colbert is known for reliability, innovation and quality. So with that out of the way, I think you're starting to get a sense of the colbert bumblebee, and you're starting to get an interest in pollination. With regard to colbert bumblebee, yunnan ucr research institute and colbert Netherlands have entered into a strategic partnership to provide high-quality bumblebees and professional technical services to yunnan growers, so as to maximize the pollination potential of bumblebees and create the maximum value for our customers.
