Abstract: Over-reliance on hormones and chemical pesticides during the pollination and pest control often appeared in large-scale planting of winter jujube. To solve these two problems, a demonstration area was established to explore the integrated application of bee pollination and pest green control techniques. Moreover, a complete set of techniques related to bee protection, fruit safety and enhancement of bee pollination efficiency were also integrated. The effects of bee pollination and its effective radius on fruit setting and development were mainly analyzed via field plot tests. The results showed that the effective pollination radius was 150 m. Compared with conventional gibberellin pollination, the fruit deformity rate was reduced by 57.14% under bee pollination. Under the same condition, the weight of longitudinal stem, longitudinal perimeter and fruit weight increased by 2.25 mm, 6.72 mm and 1.43 g, respectively. In addition, both of fruit quality and fruit commodity rate were improved significantly through bee pollination. In detail, compared with gibberellin pollination, the fruit commodity rate increased by 7.1% under bee pollination, and the market price was raised by 1.5 yuan per kilogram accordingly. In conclusion, gibberellin pollination can be replaced by bee pollination, the latter could ensure fruit setting, reduce the fruit deformity rate, promote fruit quality and increase the income of growers.
