Description

A device and method for collecting and pollinating whole-tree crops based on ion airflow

Technical Field

The present invention relates to the technical field of agricultural pollen collection and pollination, and in particular to a device and method for collecting and pollinating pollen from a whole tree of crops based on ion airflow. The device and method for collecting and pollinating pollen from a whole tree of crops based on ion airflow can be applied to collecting and pollinating pollen from a whole tree of crops, and are particularly applicable to collecting and pollinating pollen from cross-pollinated crops.

Background technique

At present, the collection and pollination of crop pollen are mainly done manually, but manual pollen collection and pollination not only consume a lot of labor, high operational risks, low operational efficiency, and high production costs, but also because the pollen is light in weight and the nectar secreted by the flowers will stick to the pollen, making pollen collection difficult and difficult to ensure the pollen quantity required for auxiliary pollination. In addition, manual pollen collection cannot ensure the activity of pollen, which greatly affects the pollination rate and efficiency of crops, and affects the fruit setting rate of crops and the increase of crop yield. Therefore, there is an urgent need for machinery to replace manual labor. Invention patent CN114793887A (a pollen collection device and collection method), the device shakes the pollen collection cover to scatter pollen into the pollen collection cover, and the pollen enters the bottom filter cartridge mechanism after sliding the conical cylindrical pollen collection cover and filtering the filter screen and filter net. The filter cartridge mechanism enters the carrier tube through the cooperation of the conical surface and the powder outlet hole. When the pollen collection cover is fully fitted with the flower, the suction pipe is pulled to extract the scattered pollen inside the top pollen collection cover through negative pressure. The device needs manual assistance to collect pollen, and still has high labor intensity and low production efficiency. Invention patent CN109819890A (a drone for spraying camellia pollen) allows airflow to spray camellia pollen through the telescopic tube under the collecting tube and the air inlet set on the expansion tube. However, since the pollen in the hose is sprayed by airflow, the spraying amount cannot be adjusted, which will lead to waste of pollen and uneven pollination. Therefore, the present invention proposes a whole-tree crop pollen collection and pollination integrated device and method based on ion airflow, which avoids the defects of the prior art such as small pollen collection amount, high production cost, low operation efficiency, easy damage to flowers during operation, large amount of pollen used during pollination, and uneven pollination. It can be applied to pollen collection and pollination of crops of different tree types, and is particularly suitable for pollen collection and pollination of cross-pollinated crops.

In view of the above problems, the present invention proposes a device and method for collecting pollen from a whole tree of crops based on ion airflow to solve the above background problems. The device and method for collecting pollen from a whole tree of crops based on ion airflow innovatively combines pollen collection and pollination into one, and can be applied to pollen collection and pollination of crops of different tree types, especially for cross-pollination crops.
