The project team selected the Yong'an Qingeng Orchard in Ansha Town,Yong'an City,Sanming City to conduct bee pollination experiments on grapefruit.The total area of the orchard is about 34 hectares,with a variety of fruit trees,mainly including American grapefruit,golden honey grapefruit,golden tribute grapefruit,navel orange and other varieties.The experimental results showed that bee pollination of grapefruit increased yield by 31.8％compared to manual pollination in a net shed,with an increase of 2650 kg/Mu.Calculated at a wholesale price of 7 yuan/kg,it is expected to increase income by 185500 yuan/Mu;Compared to net shed without bee pollination,the yield increased by 63％,with a yield increase of 4285 kg/Mu and an increase of 30000 yuan/Mu in income.The first grade yield rate of grapefruit has increased from 80％in previous years to 95％,and related indicators such as fruit set rate and seeds have all been improved to varying degrees,indicating that digital bee pollination has a very significant effect on improving the quality of grapefruit(1 hectare=15 Mu).
