Special pollination pen for artificial cross breeding

Abstract

The invention provides a special pollination pen for artificial cross breeding. The special pollination pen is characterized by comprising a sleeve head and a refill which is in rotary connection withthe sleeve head, wherein the sleeve head is of a semi-oval tubular structure with one sealed end; threads are arranged at the inner side of an opening end of the sleeve head and the outer side of a tip of the sleeve head; the refill comprises a pen tube ad a retractable pen top in the pen tube; threads are arranged at the outer sides of two ends of the pen tube; the threads at two ends of the pentube are mutually adaptive to the threads at the two ends of the sleeve head; the thread at the outer side of the tip of the sleeve head is located at the thickest part of the sleeve head. The pollination pen provided by the invention integrates pollen, alcohol and the pollination pen and artificial pollination operation is greatly convenient to realize; the pollination efficiency is also improved; the time is saved and the special pollination pen is convenient to carry; a plurality of pollination collectors are integrated and a condition of leaving equipment behind or losing the equipment isnot easy to cause.

Description

technical field [0001] The invention belongs to the field of agricultural instruments, in particular to a special pollination pen for artificial cross breeding. Background technique [0002] Hybridization as a scientific method not only promoted the birth and development of genetics, but also has always been the main means for breeders to create variations and breed new varieties. With the continuous development of modern genetics theory, methods of artificially creating new variations and new breeding approaches are also emerging, but so far, the most effective breeding method is artificial cross-breeding. Artificial cross-breeding is based on the heterosis of hybrid parents and the study of dominant-recessive genetics, and predicts hybrid offspring with a goal, which speeds up the breeding of new varieties. In addition to the strict screening of hybrid parents, artificial hybrid breeding needs artificial assisted pollination with the help of pollinators or pollinators. A...

Problems solved by technology

However, since pollination pens or pollinators, pollen, and alcohol are separate independent samples, and there may be multiple pollen, it is easy to forget to bring it before going out or lose or drop it during field operations, resulting in the failure of artificial cross-breeding and delays.
