There are bees, then why do bees pollinate strawberries? After the bees are bought, how to place the *********; how to manage the colony when the bees are pollinated... On November 14, in Shuangqiao Village, Chang'an District, Xi'an, a beekeeping expert gave a local strawberry garden The owner took a lesson on how to train bees to directional pollinate strawberries.

Train bees for targeted pollination

"After the bee colony arrives at a new site, the first thing that comes out of the nest every morning is to collect bees." Shaanxi Province Bee Industry Technology

Li Jiuzhou, the chief scientist of the system, said that based on the specificity of bees, he found a trick to train bees to directional pollination.

"The bees that have just been put in the strawberry greenhouse, if they have not adapted to the environment, the strawberry pollen will not be interested." Li Jiuzhou introduced that in order to solve this problem, the picked strawberry flowers should be soaked in sugar water and then placed next to the beehive. , To attract bees to gather nectar. As long as they suck the strawberry flower for the first time, the bees will start to act. "When the bees enter the greenhouse, they must ensure that they are all young adults, and the queen bee is still laying new eggs, so as to ensure the balance of the bee colony." Li Jiuzhou introduced, The life cycle of bees is very short. Newly born bees are young adults, while bees between 20 and 25 days old are elderly bees. This also means that most of the newly born bees can pollinate flowers.

Be careful about placing beehives

Before placing the bees, be sure to check in advance. The temperature and humidity in the greenhouse, the most suitable temperature for the bees to live, are around 20 degrees Celsius, floating around 5 degrees. If the temperature is below 10 degrees Celsius, the bees will basically not come out.

Xie Liquan, chairman of Yangling Fengqianhui Beekeeping Professional Cooperative, said that if you want to put bees into the greenhouse, you must control the temperature in advance. If the temperature is too high, you must ventilate it in time. If the temperature is too low, you need to seal the greenhouse. Increase the temperature.

How to put the bees after they are bought? Xie Liquan said that if a group of bees is placed in a greenhouse, the hives should be placed in the middle of the shed, and the hives should be placed on the supports between the crop ridges, about 30-50 cm from the ground.

In addition, the beehive should be placed in the evening, mainly to allow the bees to adapt to the air in the greenhouse and the surrounding environment. Xie Liquan said that when the temperature rises in the second weather, the bees will fly out to pollinate and will not adapt to the environment again. If there are few bees in the beehive, you can properly feed some honey syrup. Put the honey syrup on the air outlet to lure the bees out, which can greatly increase the bee attendance rate.

So, how can we decide how many bees to put in? Xie Liquan explained that the number of bee colonies is actually mainly determined by the area of ​​the greenhouse. Under normal circumstances, a box of bees is appropriate for a strawberry greenhouse on an acre of land. Of course, the number of bee colonies is appropriately increased by the amount of strawberry blooming.

Pollination can improve yield and quality

Strawberries planted in facilities generally bloom in colder seasons. At this time, the environment in the facility is closed and there is no wind, and insects cannot enter. Strawberries can be pollinated by wind and insects. Moreover, the temperature in the facility is low and the humidity is high. bad. Only relying on natural pollination, the yield of strawberries is low, the size is small, and deformities are prone to occur.

"Using honeybees to pollinate greenhouse strawberries not only improves strawberry yield and quality, saves labor, time, and has a high fruit setting rate, but also has a low malformed fruit rate and good commercial properties." Xie Liquan said, using honeybees to pollinate the strawberry fruit setting rate Strawberry single fruit weight, vitamin content and sugar-acid ratio are all increased.

As Xie Liquan, who has been engaged in bee pollination for more than ten years, he will use bees to directional pollinate fruits and vegetables and will extend it to pear, kiwi, cucumber, eggplant, cabbage and other crop varieties.
