To use chemical fertilizers rationally,reduce the resources waste and enhance fertilization efficiency,42 “3414” field experiments for late rice were conducted in 13 counties and regions in Ji′an city,Jiangxi Province from 2008 to 2010 to study the effect of soil testing and formulated fertilization on rice production.The results showed that the relative yield of late rice was 60%-85% when soil alkali-N content ranged from 116 mg/kg to 209 mg/kg.The recommendation of fertilizer N rate for late rice was 110-210 kg/hm2.The relative yield of late rice was 85%-100% when soil available K content ranged from 61 mg/kg to 119 mg/kg,indicating applying potassium fertilizer could improve yield.The recommended amount of K fertilizer application was 0-130 kg/hm2.There were high soil available P content and relative yield of late rice in the experimental regions,which were 11-31 mg/kg and 85%-100%,respectively.Fertilizing quantity recommended for P was 0-80 kg/hm2.The effect of P fertilizer was inferior to N and K.The recommended nitrogen fertilizing level calculated according to the high soil alkali-N content and low relative yield of late rice was relatively high.
