A kind of resource fir control powder type dry pollinator

Abstract

The invention discloses a resource fir powder-controlling dry pollinator, comprising a handle, one end of a square tube is fixedly connected to one side of the top of the handle, the other end of the square tube is rotatably connected with a pollination shell, and the pollination shell and the top of the square tube are slidably connected There is a fan. The pollen shell is provided with a pollen box, a pollination cover and a pollination cabin from top to bottom. The pollen box and the pollen cover are connected. The leaf ball, the bottom of the pollination shell is fixed with a rotating opening, and the handle is provided with a switch. The pollen in the pollen box falls into the gap channel between the pollination cabin and the pollination shell through the pollination cover, and enters the pollination cabin with the airflow generated by the fan. , and moves upward from the bottom of the pollination chamber. During the upward movement, the pollen can directly enter the opening of the inverted bead scale on the macrosporophyte ball of the resource fir, and complete the pollination efficiently. The structure contributes to the inefficiency of other pollination methods.

Description

technical field [0001] The invention relates to the field of plant pollination and breeding equipment, in particular to a resource fir control type dry pollinator. Background technique [0002] Resource fir is an endangered plant unique to China. Because of the very small number of existing plants, it is listed as a national class I key protected wild plant. Resource fir is a dioecious plant, because most plants usually only develop macrosporophyll (female bulb), and only a few plants develop microsporophyll (male bulb). For many reasons, the megasporophylls of most plants lack pollen sources for pollination, resulting in severe seed abortion, which greatly limits the seedling renewal and individual replenishment of their wild populations, which is very unfavorable for the species to escape from the endangered state. To alleviate this problem, artificial pollination and breeding of resource fir are required to obtain the active seeds of the plant. [0003] In the pollinati...

Problems solved by technology

Under this anatropic ovule structure, in order to make the pollen fully enter and stick tightly in the mouth of the pearl scale opening downward, it is necessary to repeatedly use a pollination pen on the megaspore leaf ball, which is not only time-consuming and labor-intensive, but also inefficient. And it is a waste of pollen, it is difficult to pollinate the resource fir on a large scale

Some existing sprinkler pollination devices for other plants are not developed for the megaspore ball with anatropic ovule structure, pollen cannot accurately enter the pearl scale mouth, not only the success rate of fertilization is low, but also a large amount of pollen Waste, so it is not suitable for large-scale pollination breeding of resource fir
