Quantity-controllable dendrobium officinale pollination pen

Abstract

The invention relates to the technical field of pollination pens, in particular to a quantity-controllable dendrobium officinale pollination pen which comprises a pollen outlet module. The pollen outlet module comprises a pen tube and a first round rod, a first annular baffle is fixedly connected to the middle of an annular inner wall of the pen tube, and a second annular baffle is fixedly connected to the annular inner wall of the end, deviating from the tip, of the pen tube; and the first round rod is slidably connected with the first annular baffle and the second annular baffle in a sleevedmanner. According to the quantity-controllable dendrobium officinale pollination pen, through the arrangement of a clearing module, when a pollen feeding pipe moves inwards, a blocking piece makes contact with the inner wall of the pollen feeding pipe, pollen on the inner wall of the pollen feeding pipe is scraped off, the accuracy of the pollination quantity of pollen each time is improved, andtherefore the pollination rate is increased; through the arrangement of a threaded sleeve, the maximum moving distance of the first round rod is adjusted, so that the moving distance of the pollen feeding pipe is adjusted, and the pollination quantity of the pollen each time can be adjusted according to needs; and meanwhile, due to the arrangement of a pressing plate, the quantity-controllable dendrobium officinale pollination pen is convenient and quick to operate, and the pollination work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chalk pens, in particular to a controllable amount of dendrobium candidum chalk pens. Background technique [0002] The pollination rate of Dendrobium officinale is low under natural conditions, and the quality of the fruit it bears is poor. When used as seeds, the germination rate is low. At the same time, it needs a lot of nutrients to bloom and bear fruit, but on average, we only need a small part of the flowers Fruit setting can meet our output. Most of the nutrients consumed by flowers and fruits are wasted. Artificial pollination technology can not only save a lot of nutrients to ensure the normal growth and development of selected fruit, but also save a lot of labor for fruit thinning. [0003] Existing artificial pollination pens mostly use brushes for pollination, pollen is easy to adhere to the brush, and the amount of single pollination cannot be controlled, making the amount of pollen pollinat...

AI Technical Summary

Problems solved by technology

[0003] Existing artificial pollination pens mostly use brushes for pollination, pollen is easy to adhere to the brush, and the amount of single pollination cannot be controlled, making the amount of pollen pollination uneven, resulting in the pollination rate of flowers in the later period cannot be guaranteed. The time suitable for pollination in a single day is limited, and the pollination speed of the brush pollination pen is slow and the pollination efficiency is low
