Annona squamosa Linn requires artificial pollination when fruits are set under normal conditions, pollen is collected in advance one day before pollination, and artificial pollination is carried out in the next morning and evening, which is extremely labor-consuming and time-consuming and has extremely high requirements on the operation technical level of workers, so that a large amount of manpower is often required for pollination in production. The excessive labor added value causes the cost of the cherimoya fruits to be high, and meanwhile, the pollination workers have uneven technical levels to cause low fruit setting rate, deformed fruits and difficult guarantee of yield and quality. The artificial pollination is large in workload, short in time and heavy in task, the pollination time of the sweetsop flower buds is extremely short, and pollination failure of the sweetsop can be caused early or late in pollination, so that the fruit setting of the sweetsop is influenced.
