| Rice-fish co-culture system is a modern agroecology practice that can improve the farmland ecological
environment and increase the efficiency of energy flow and nutrient cycling. In recent years, researchers have made great
progress in the theoretical researches and technical promotion of rice-fish co-culture system in China. Rice-fish coculture system shows obvious advantages over the conventional practice in reducing fertilizers and pesticides, increasing
rice production and efficiency, and improving soil and water physicochemical properties. Furthermore, rice-fish co-culture
system can guarantee food security, increase farmers' income and reduce non-point source pollution, with good economic, ecological and social benefits. Currently, the area of rice-fish co-culture systems is still small in Guangdong Province. In
this paper, we summarize and analyze the situation and the advantage of nature resources of the rice-fish co-culture system
in Guangdong Province, and pointe out some problems such as small application area, low production, backward technology
development and promotion, poor water and fertilizer management, few rice and fish varieties for the rice-fish co-culture
system, and lack of mechanization and intelligentization technology. It is believed that rice-fish co-culture system would
have an extensive market prospect in Guangdong Province. Therefore, it is proposed to strengthen policy support and provide
guidance for industrial development, to enhance support for key technologies, to improve technical specifications and boost the
integration of three industries, and to promote rural revitalization, so as to provide technical guidance for the development of the
rice-fish co-culture system in Guangdong Province. |
