测土配方施肥对水稻经济性状、产量及经济效益的影响

Effects of Soil Testing and Formula Fertilization on Economic Characters, Yield and Economic Benefit of Rice

2008～2010年在江西省吉安市13个县(市、区)开展了测土配方施肥田间试验,研究了当前生产条件下水稻测土配方施肥、常规施肥对水稻主要经济性状及产量和经济效益的影响,结果表明:与常规施肥处理相比,测土配方施肥处理的早、中、晚稻平均增产分别为524.85、798.50、647.15 kg/hm2,平均增收分别为475.45、1296.90、886.55元/hm2。水稻测土配方施肥比常规施肥具有明显的增产和增收作用。

The field experiments for soil testing and formula fertilization were conducted from 2008 to 2010 in 13 counties （ cit- ies, districts） of Ji＇an city, Jiangxi province. We studied the production of rice under the condition of formula fertilization based on soil testing. More than 3 years＇ location test results Showed that： as compared with the treatment of conventional fertilization, the treatment of soil testing and formula fertilization increased the average yield of early, middle and late rice by 524.85, 798.50 and 647.15 kg/hm2, respectively, and enhanced their income by 475.45, 1296.90 and 886.50 yuan/hm2, respectively. So soil testing and formula fertilization for rice had obvious effects of increasin~ rice yield and income than conventional fertilization
