Study On The Popularization Of Rice-Crab Symbiotic Technology In Wensu County

Wensu County is rich in rice,which the annual rice area is stable at 10,000 hectares.The rice industry has a certain scale,and the quality of rice is excellent.So it was named as the "Hometown of Chinese Rice"in 1998.The use of land resources by monoculture rice is very inadequate.Plankton and weeds compete with rice in terms of soil nutrients,water and light,which is not conducive to protecting the ecological environment.Simple rice planting with a large amount of chemical fertilizers and pesticides has caused damage to the ecological environment.The report of the 19th National Congress also pointed out that "we must establish and practice the concept that clear waters and green mountains are as valuable as moutains of gold and silver." However,rice-crab symbiotic fields can make full use of the land and hardly use chemical fertilizers and pesticides.The rice produced is green and natural,and the market price is high.Therefore,it is the core of this paper to establish a breeding model of rice-crab symbiosis and promote this technology.Based on the theories of agricultural extension,agricultural technological innovation and sustainable development,this study summarizes the relevant researches at home and abroad on the background and significance of the research on rice-crab symbiosis technology extension.Taking the actual situation of rice-crab symbiotic technology popularization in Wensu County as the research object,through interviewing and investigating the stationmaster of agricultural technology popularization station,rice-crab symbiotic farmer and non-rice-crab symbiotic farmer,the practical problems existing in rice-crab symbiotic technology popularization in Wensu County were dicussed.The causes of the problems were analyzed and then put forward the countermeasures and suggestions for the development of rice-crab symbiotic technology in Wensu County.Some countermeasures and suggestions were put forward for the problems in the promotion of rice-crab symbiosis technology in Wensu County.The government should strengthen policy support and policy implementation,establish a supporting regulatory mechanism for the policies already issued and ensure the effective implementation of the policies.The conditions of agricultural technology are completed at the grass-roots level and improved the quality of the promotion team.At the same time,it will transform the role of the government,increase funding and corporate services,establish brand effects and encourage the development of social organizations to promote the promotion of rice-crab symbiosis technology in Wensu County.
