Manual pollination device for two-end double-selection kiwi fruit

Abstract

The invention provides a manual pollination device for two-end double-selection kiwi fruit. The manual pollination device for two-end double-selection kiwi fruit is provided with a pollen container,an external thread bottle mouth with diameter larger than 30mm, a bottle cap, a first connecting pipe with 8-12mm internal threads made of hard material, a hard tubule and a second connecting pipe with internal threads, an inverted conical large-head powder outlet nozzle I with a plurality of spray holes connected with the hard tubule through a second connecting pipe; and a straight cylinder cap type structure small-head powder outlet nozzle II with a spray hole in center is also connected with a tubule. The manual pollination device for two-end double-selection kiwi fruit has the advantages of simple structure and low cost, and can freely switch and select large-headed umbrella-shaped scattering ejection powder and small-head single-column ejection powder mode, is simple and convenient toinstall and replace, and effectively solves the technical problem that the traditional manual pollination device cannot achieve the size switching of the spray head.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to a manual pollinator for double-selecting kiwifruit at both ends. Background technique [0002] Actinidia is a dioecious plant, and insufficient pollination will make the fruit smaller, with poor flavor and quality. Generally, the ratio of male to female is 8:1. However, if the male and female plants meet at the flowering stage and it rains continuously, wind pollination and insect pollination alone cannot fully meet the needs of normal pollination. Therefore, in order to avoid the impact of poor pollination on high-quality fruit yields The operation of artificial pollination must be assisted. The existing hand-held device for artificial jet pollination has a simple structure, but when encountering the pollination of stamen heads that require concentrated pollination and relatively sparse and scattered stamen heads, it is impossible to adaptably select large-end pollination or s...

Problems solved by technology

[0003] The technical problem solved by the present invention is to provide a manual pollinator for kiwifruit with two ends and double selection, which solves the problem that the hand-held pollination device with a simple structure, economical and practical single powder outlet cannot selectively use the large head or small pollinator according to the density of the target stamens. Head pollination, pollen waste and over-pollination are more prominent technical problems
