Convenient isolating device for directed hybrid pollination of plant

Abstract

The invention discloses a convenient isolating device for directed hybrid pollination of a plant. The device comprises an upright column, a hanging frame and a pollination sleeve, wherein the upright column is a hollow rod body; a plurality of small holes with different heights are formed in the upper part of the upright column; one end of the hanging frame is bent to be inserted into one of the small holes, and an open circular ring is arranged at the other end of the hanging frame; the pollination sleeve comprises an upper circular ring, a lower circular ring and a barrier paper / film; a proper interval exists between the upper circular ring and the lower circular ring; the barrier paper / film coats the upper circular ring and the lower circular ring and is fixed to the exteriors of the upper circular ring and the lower circular ring, so that the pollination sleeve is shaped like a cylinder which has a closed upper end and an open lower end and is internally provided with an accommodating space; a connecting piece is fixedly arranged at the upper end of the pollination sleeve; the pollination sleeve is connected with the open circular ring of the hanging frame through the connecting piece. The device is simple in structure, and convenient to use and move, and the construction cost and the use cost can be reduced; moreover, the device is high in air permeability, is used for enabling an outdoor plant to grow in a natural environment so as not to influence the normal growth of the plant, can effectively prevent the entry of foreign pollen, and is superior to a conventional bagging method in terms of directed hybrid effect and reliability.

Description

technical field [0001] The invention belongs to the field of agricultural production, and relates to a plant directional hybridization pollination isolation method, in particular to a convenient plant directional hybridization pollination isolation device established by using a column, a pollination cover and a hanger. Background technique [0002] In the process of directional hybridization in agricultural production, in order to prevent the pollution of the target pollen, it is necessary to create a closed microenvironment to protect the pistil before pollination of the stamens and after artificial pollination. The traditional method is to manually bag the flowers or inflorescences of plants. Although this method is simple and economical, it has disadvantages such as poor air permeability, easy mold growth in the bag, heavy rain and accumulated water, which will easily break the branches, and easy to fall off in the wind. . Smart greenhouse, also known as automated greenh...

Problems solved by technology

The smart greenhouse can also be used for isolated planting during hybrid pollination, which can improve labor productivity, but the smart greenhouse has the characteristics of high cost and high cost of use, and pollination is prone to occur when the pollen concentration in the greenhouse is high
