摘  要：
针对江西省水稻生产中普遍存在的氮肥施用量大、无效分蘖增多、成穗率低、病虫害严重等问题,从广东引进"三控"施肥技术,在南昌、安福和广昌进行了试验示范。结果表明,应用该技术平均每667 m2增产稻谷41.9 kg,增幅7.9%,节省农药肥料成本32.05元,增收节支109.15元,病虫害和倒伏减轻。该技术在江西不同示范点都表现节本增产,经济效益好,且易操作,适宜在江西推广。

摘  要：
Overuse of nitrogen fertilizer,excessive unproductive tillers and heavy occurrence of diseases and insects are common problems in the rice production in Jiangxi province.To solve these problems,the "Three controls" technology developed was introduced from Guangdong province and field trials and demonstrations were conducted in 2009 at Nanchang,Anfu,and Guangchang counties of Jiangxi province.In average,Per 667 m2 grain yield of "Three controls" technology was 41.9 kg or 7.9% higher than that of farmer's fertilizer practice(FFP).Fertilizer cost was 32.05 yuan/667 m2 lower for "Three controls" technology than for FFP.Per 667 m2 profit was 109.15 yuan greater for "Three controls" technology than for FFP.The occurrence of lodging,diseases and insects was much lower for the "Three controls" technology than for FFP.We suggest the "Three controls" technology be applied in rice production in Jiangxi province as a fertilizer and cost-saving,yield-raising and easy-to-use technology.
