水稻“三控”施肥技术的示范推广进展

Progress in demonstration and extension of "three controls" technology for rice

水稻"三控"施肥技术自2007年通过技术鉴定以来,作为广东省农业主推技术,被广泛用于粮食高产创建和超级稻示范活动中,在广东各地迅速推广,并辐射到江西等省区,取得了显著的节本增产增收效果。多年多点示范表明,该技术比习惯栽培技术增产8%左右,节省肥料成本20%左右,每667 m2增收节支100元以上,倒伏和病虫害明显减轻。还介绍了近年来水稻"三控"施肥技术示范推广的主要经验和做法。

Since its official appraisal in 2007,the ＂three controls＂ technology was adopted as the government-recommended technology in Guangdong province and widely used in high yield creation and super rice demonstration activities.Demonstration trials were also conducted in Jiangxi and some other neighboring provinces.Multi-year and multi-location tests and demonstrations showed that,in comparison to farmer＇s practice,the ＂three controls＂ technology can normally save about 20% fertilizer cost with a yield gain of about 8%.The profit was at least 100 yuan/667m2 higher than farmer＇s practice.Lodging and damage from diseases and insects were significantly reduced.Finally,experiences and measures in demonstration and extension of the new technology were discussed in this paper.
