Direction-changing telescopic kiwifruit pollen contact pollination device

Abstract

The invention discloses a direction-changing telescopic kiwifruit pollen contact pollination device. The direction-changing telescopic kiwifruit pollen contact pollination device comprises a pollen cylinder, wherein a piston core rod is inserted from the back end of the pollen cylinder and matched with the pollen cylinder, a movable cylinder cover is arranged at the front end of the pollen cylinder, a screw rod is arranged in the middle position on the outer surface of the pollen cylinder, the front end of a direction-changing telescopic rod is sleeved on the screw rod, and the direction-changing telescopic rod is fixed through a butterfly-shaped screw nut. When the direction-changing telescopic kiwifruit pollen contact pollination device is used, pollen is loaded in the cylindrical pollen cylinder and on the piston core rod, the direction-changing telescopic rod is held by the hand to enable the pollen to be in contact with a pistil stigma for pollination, and the piston core rod is pushed and pulled to control the pollen to be in full contact with the pistil stigma; and when the direction-changing telescopic kiwifruit pollen contact pollination device is not used, the movable cylinder cover can be used for sealing and preservation. The direction-changing telescopic kiwifruit pollen contact pollination device can well avoid the problem of difficulty in pollination, such as high and far positions of pistillate flowers caused by tree vigour of kiwifruits by using direction-changing and telescopic effects, and has the advantages of high pollination quality, easiness in operation, high working efficiency, simple structure, low cost, broad application prospects and the like.

Description

technical field [0001] The invention relates to a direction-adjusting telescopic kiwifruit pollen contact pollinator, which belongs to the technical field of agricultural cultivation equipment. Background technique [0002] Kiwifruit (Actinidia) is recognized as an emerging fruit in the world. Its fruit contains a variety of amino acids and vitamins, as well as rich trace elements. It plays an important role in maintaining human health and has broad development prospects. Since entering the 21st century, there have been new changes in kiwifruit production, trade and competitiveness both in the world and in China. China's kiwifruit industry has developed rapidly, and its cultivation area and output both rank first in the world. However, China's kiwifruit import volume and import value are far greater than export volume and export value, and its export competitiveness is at a very poor or even extremely poor level. The reason is that the quality of kiwifruit exported from Chi...
