Handheld pollinator for medicago sativa. L

Abstract

The invention relates to a handheld pollinator for medicago sativa. L. The handheld pollinator consists of two independent micro auxiliary pollinators and a micro pollen collector, wherein each micro auxiliary pollinator comprises a gun body horizontal end and a gun body vertical end which are connected together; a pollination chamber is formed in the gun body horizontal end and is provided with a pollination pipe, a pollen container and a micro motor; the micro motor is connected with a power spiral stick extending to the pollen container; a fixed baffle and a movable baffle are respectively arranged in each pollination chamber; the tail end of each pollination chamber is connected with a pollen transferring bin and an air blowing cavity in sequence; a transferring bin opening is formed in the upper end of the pollen transferring bin; the air blowing cavity is provided with a hand-operated fan, an air blowing cavity air return pipe and a hand-operated switch ON / OFF; a telescopic handle is arranged in each gun body vertical end; the micro pollen collector comprises a pollen collector handle, a pollen collection bin and a detachable pollen collection cover; a telescopic pollen collection head, the pollen collector handle, a pollen transferring opening of which the tail end is provided with a micro filter net, and a piston are arranged on the pollen collection bin. The handheld pollinator disclosed by the invention is easy to operate and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of artificial detasseling, artificial pollination, reproduction and breeding of Papilionaceae Medicago genus alfalfa, in particular to the field of leguminous forage grass Medicago sativa ( Medicago sativa . L) Hand-held pollinators. Background technique [0002] Under natural conditions, the pollination of the fine leguminous forage alfalfa mainly depends on insect pollination. On the one hand, pollinators play an important role in shaping the flower structure, pollen transfer, and the construction of pollination systems; direction evolution. However, due to the unique papilionaceous flower structure and cross-pollination characteristics of alfalfa, pollination has always been an important factor restricting the genetic improvement of alfalfa. [0003] According to the different pollination methods of plants, it can be divided into two types: natural pollination and artificial assisted pollination. For ...

Problems solved by technology

However, due to the unique papilionaceous flower structure and cross-pollination characteristics of alfalfa, pollination has always been an important factor restricting the genetic improvement of alfalfa.

However, the technical content disclosed in the above-mentioned patents only relates to the single series technology of artificially assisted pollinators, and there are still the following deficiencies: (1) pollinators can only pollinate, and lack the artificial detasseling of female plants; (2) pollination The pollinator is inconvenient to collect pollen, and the pollinator is easy to slip during pollination, pollination is uneven, and operation is inconvenient, resulting in low seed setting rate; (3) During the long-term use of the pollinator, the pollination head is often blocked by pollen, resulting in uneven pollination ; (4) The disassembly and assembly of pollinators is inconvenient and difficult to clean, resulting in short pollination time and increased pollination costs, which leads to the inability of universal use of electric pollinators; (5) Conventional pollinators are mainly designed for flowers and fruit trees, mostly Rosaceae or cruciferous family plant

[0008] In summary, considering that alfalfa is one of the most important cultivated pastures in my country, with a large planting area and a high demand for germplasm resources, and the existing pollinators often have pollen in the pollination head of alfalfa. Blockage, which leads to problems such as uneven pollination
