Pollination device and method for increasing hand pollination effect of annona squamosa by utilizing pollination device

Abstract

The invention relates to the technical field of agricultural application, in particular to a pollination device and a method for increasing the hand pollination effect of annona squamosa by utilizingthe pollination device. According to the pollination device disclosed by the invention, the pollination efficiency is increased, the fruit setting rate is increased, and the generation of malformed fruits is reduced. According to the method disclosed by the invention, the pollination time is prolonged, and pollination can be favorably carried out by a large-scale orchard. The pollination device comprises a pipe sleeve, a pushing rod, a piston and a powder storage pipe, wherein a sliding cavity is formed in the pipe sleeve; a poking hole is formed in the side wall of the pipe sleeve; a pollination hole is formed in the front end of the powder storage pipe; the width of the pollination hole is 4 to 6 mm. The method adopts the pollination device one of any of claims 1 to 4 and comprises the following steps: (1) building spray irrigation facilities in an annona squamosa planting orchard, wherein the height of spray nozzles spaces from the annona squamosa by 40 to 50 cm, and water can be prevented from being sprayed to flowers; (2) starting to spray the water ahead of pollination by one hour when annona squamosa blooms, and enabling the humidity of the orchard to be up to 70 to 80 percent; (3) enabling the pollination time to be before 9 o'clock in the morning and after 17 o'clock in the afternoon.

Description

technical field [0001] The invention relates to the technical field of agricultural application, in particular to a pollination device and a method for improving the artificial pollination effect of custard apple by using the pollination device. Background technique [0002] As everyone knows, the traditional method is to collect the mature flowers of the stamens, take out the anthers and pollen, and use a writing brush to get the pollen and give it to the pistil. Due to the small opening angle of the petals, it is difficult for the brush to sweep the stigma, the pollination efficiency is low, and the pollination is uneven, and deformed fruits are prone to appear. The flowers of custard apple are hermaphroditic and the pistil is an aggregate flower with non-single stigma, but because the flower has dioeciousness (pistil promaturity), that is, when the pistil matures to the pollination period, the stamen is not yet mature, and when When the stamens mature and the anthers deh...

AI Technical Summary

Problems solved by technology

The anthers of Atimoye cherimoya split open at 17:00-20:00 in the afternoon. At other times, there is no pollen and artificial pollination cannot be carried out. The pollination time is relatively short, generally only 2-3 hours after flowering, which is not conducive to field production.

The traditional method is to collect flowers with mature stamens, take out the anthers and pollen, and use a brush to pick up the pollen and transfer it to the pistil; because the petals open at a small angle, the brush is not easy to sweep to the stigma, and the pollination efficiency is low
