Popularizing bumblebee pollination to promote high yield of tomatoes in Qingdao

In the middle of winter, tomatoes and strawberries in some solar greenhouses in our city began to blossom and set fruit. A few days ago, the Municipal Agricultural Technology Station held an on-site observation meeting of bumblebee pollination of greenhouse vegetables in Jimo to promote this technology. It is understood that using bumblebees to pollinate greenhouse vegetables is a low-cost, high-efficiency and pollution-free agricultural technical measure. Compared with artificial hormone pollination, bumblebee pollination can reduce the incidence of Botrytis cinerea, reduce labor consumption, reduce the use of chemical pesticides and flower hormones, increase vegetable yield by 20% and 30%, and reduce the rate of abnormal fruits by 30% and 60%.

Bumblebees have been widely used in the pollination of protected and open-air crops in the world. China obtained the successful technology of bumblebee artificial breeding as early as 1999, but up to now, bumblebee pollination has not been widely used in our city. In our city about 100000 mu of solar greenhouse, the use of bumblebee pollination is only a few thousand mu. The survey found that the majority of vegetable growers have concerns about the application cost of this technology, bumblebee management methods, production effect and so on. "A box of bumblebees (40-50) costs between 350 and 400 yuan and stays in the greenhouse for about 1 to 2 months. If you put two boxes in each greenhouse, the light cost will be more than 700 yuan. Nowadays, large vegetable bases are widely used because the cost of bumblebees is similar to that of manual labor. Bumblebees are not widely used in greenhouses managed by farmers. However, as the cost of bumblebee use falls, this technology is expected to be more widely used. " Introduction of the staff of the municipal agricultural technical station.

In order to popularize and apply bumblebee pollination technology as soon as possible, Colbert bumblebee was introduced from Holland and domestic bumblebee from Jinan in Qingdao Agricultural Technology Station, and a comparative experiment of bumblebee pollination was carried out in Qingjian Momoshangchun vegetable standard garden. In terms of pollination effect, there was no significant difference between domestic bumblebee and imported bumblebee. Compared with artificial hormone pollination, bumblebee pollination can reduce the incidence of Botrytis cinerea, reduce labor consumption, reduce the use of chemical pesticides and flower hormones, increase vegetable yield by 20% Mel 30%, and reduce the rate of abnormal fruits by 30% Mel 60%. Vegetables taste good, too.
