Research progress of ecological efficiency and developing strategies for paddy-field conservation tillage
摘要
Abstract
This paper firstly expounded the developing situation of conservation tillage at home and abroad, pointed out the main problems of conservation tillage in China: innovation research of key technology was not enough. up to now, paddy-field cropping system, tillage mode and technical system which has the characteristic of southem China were not yet formed. The conservation tillage machine which matching to the unique natural and geographical conditions, complex paddy-field cropping system in the south of China needs more research. Promoting technology guarantee system is weak, the promotion mechanism which suitable for rural actual situation needs into-step exploration. Secondly, this paper reviewed the latest research progress of ecological efficiency in paddy-field conservation tillage. Such as soil physical and chemical properties, soil biological characteristic, energy-saving and emission-reduction, integrated pest prevention and control, etc. Finally, this paper put forward three strategies which are aiming at the development of paddy-field conservation tillage in the south of China especially in the southwest hills and mountains region.Increase policy support and govemment spending, establish pluralism investment mechanism. Such as policy favour, grant-in-aid,ecological compensation, etc. Strengthen key technology research, such as research on the key technology of high yield, high quality and high efficiency conservation tillage in hybrid mid-season and ratooning rice, innovation research of highly efficient farming system and conservation tillage in the southwest hills and mountains region paddy-field, energy-saving and emission-reduction research of paddy-field conservation tillage which centers on the rice field-upland field rotation. Further strengthen existing technology integration, expanding technical achievements demonstration, Accelerating technological transformation of achievements to productivity.关键词
