Study status and developmental strategies of mechanical pollination for hybrid rice breeding

Breeding is an important process of hybrid rice production. Pollination is the key link of breeding, which effect the production and economical efficiency obviously. The status of pollination equipments and technologies at home and abroad were reviewed. There were two types of pollination techniques with collision type and slipstream type based on the working principle, the features and the shortcomings of which were summarized. The problems of pollination equipment, such as pollination nonuniformity, plant scathing, resulted into pollinating blindly and randomly. Hybrid rice production should be oriented toward mechanization and multifunction. The strategies of different kinds of pollinating scientifically and applicatively, and the methods of obtaining reasonable working parameters and avoiding interbreeding and developing applicable pollination machines were explored.
