Description

Pollen isolation bag for vegetable breeding and pollen isolation method
Technical Field
The invention relates to a pollen isolation bag for vegetable breeding and a pollen isolation method, and belongs to the technical field of gardening cultivation.
Background
In the conventional vegetable breeding work, the most common method is to select excellent plants, perform individual plant selfing and seed reservation, obtain stable selfing lines and perform a hybridization and matching test. No matter the test of single plant selection or hybridization grouping is carried out, the sleeve bags can not be opened for isolation. The prior common sulfuric acid paper bag has the following defects: the material is hard in texture and inconvenient to fold at will, the sealing is difficult to be tightly attached to the flower branches, complete sealing is achieved, and the flower is easy to extrude to deform or even break the flower branches in order to achieve the sealing effect. Also, because of the relatively hard texture, the sulfuric acid paper bag cannot be used for covering multiple spikes at one time. When a plurality of flower ears or even the whole plant needs to be sleeved with bags for isolation on the same single plant, the bag sleeving work occupies more than half of the time of the whole pollination work, and some vegetable types needing repeated pollination take more time. In addition, the flowers which have been pollinated and even the seed pods (fruits) which have been grown are broken due to careless operation, and the probability is as high as more than 10%. In addition, the light transmission and the air permeability of the sulfuric acid paper bag are poor, and due to the poor light transmission, workers cannot find out that the flowering branches are bent and deformed due to the limitation of the sulfuric acid paper bag on the growth of the flowering branches in time, so that the flowering branches are broken; the above problems greatly reduce the breeding efficiency. Therefore, the bagging mode of the current vegetable breeding work needs to be improved, and the efficiency of the breeding work needs to be improved.
