Description
Technical Field
The invention relates to the field of artificial pollination devices, in particular to a pollinator for corn breeding.
Background
Corn is one of important grain, feed and industrial raw material crops in China, and the corn is the first large grain crop in China in 2007. The social popularity of the corn hybrid is extremely high, the corn seeds are the most important commercial food crops, and the commercialization degree of the corn breeding is also the highest. The traditional breeding mode in China is summarized as 'individual workshop type' breeding, namely the breeding innovation of a topic group mode. The scale is small, the efficiency is low, and the experimental analysis is excessively relied on. And the commercial breeding is most advanced in the United states, and the scale testing and identification are emphasized. And a large number of new combinations are tested and matched for a hybridization ratio identification test, so that excellent combinations suitable for breeding targets are screened out.
In the process of determining the combining ability of a large number of self-bred lines and combining and matching, one mode is to arrange an isolation region to carry out the testing and matching combination by taking the same test species as a male parent. In the mode, the male and female are uncoordinated, and artificial pollen collection is needed for auxiliary pollination; the other way is to carry out the matching force measurement by adopting the directional combination of manual pollen collection, and the way needs the auxiliary pollination of manual pollen collection if a large number of combinations need to be measured. In the conventional artificial supplementary pollination, pollen of a male parent is manually collected by adopting a sulfuric acid paper bag and then is packaged into other sulfuric acid paper bags for the artificial supplementary pollination of female parent ears of different parents. The artificial supplementary pollination method has low efficiency and poor effect.
The invention patent with application number 201110376666.3 discloses a blowing pollinator and a method for blowing pollination by using the same, wherein the method comprises a fan and an air guide device; the air outlet of the fan is connected with the air guide device, and the air outlet end of the air guide device is connected with an air nozzle; the air nozzle is an adjustable air nozzle, and the angle between the ejected air flow and the horizontal plane can be adjusted through the air nozzle; the air nozzle is vertical to the air outlet end of the air guide device, namely the flow direction of the air flow entering the air nozzle through the air guide device is changed by 90 degrees; the two air nozzles respectively face the upper left side and the upper right side of the air outlet end of the air guide device; the fan is connected with a storage battery for providing power and a flow speed adjusting device for adjusting the flow speed of the air flow. According to the blowing pollination device and the blowing pollination method provided by the invention, the mature pollen of the male parent can be directly blown to the upper space of the female parent area by using airflow, and then the pollen naturally falls to complete the pollination process, so that the maturing rate of the cross breeding is obviously improved.
Above-mentioned patent scheme has improved pollination efficiency to a certain extent, makes the maturing rate obtain improving. However, due to the blowing mode, a large amount of pollen is scattered in the air, the amount of pollen which can fall onto female parents is small, pollen collection is heavy originally, a large amount of pollen is wasted, the workload is increased to a certain extent, and therefore the comprehensive efficiency is not high. Moreover, for some breeding experiments, in small sample experiments, the method is not suitable.
