摘要

基于2013—2016年在吉林省永吉县、九台区、梨树县和前郭县开展的40组田间试验，通过研究稻谷产量、养分吸收量、肥料利用效率及养分平衡等指标，比较了测土配方（ST）与NE养分专家系统（NE）两种推荐施肥方法在吉林省中部一季稻区的应用效果与适用性。结果表明：农民习惯施肥（FP）处理稻谷产量平均为9.17 t/hm2，ST （9.21 t/hm2）和NE （9.24 t/hm2）处理产量均高于FP处理但并无显著差异。氮肥农学利用率以NE处理显著高于FP处理，磷肥农学利用率以ST处理显著高于FP、NE处理，而钾肥农学利用率无显著差异。FP、ST和NE处理的地上部养分吸收及肥料回收利用率方面均无显著差异。养分表观平衡方面，FP、ST和NE处理的土壤氮素均为盈余，其中FP > ST > NE。磷素则为小幅亏缺，而钾素大幅亏缺。不同区域处理间表现存在差异，与其他3个地区不同，前郭县ST处理的产量、植株养分吸收量及肥料农学利用率总体上低于NE处理。综上，ST和NE推荐施肥方法在吉林省中部一季稻区均有减肥、稳产、增效的良好效果，两种方法在半湿润地区（永吉、九台和梨树）适用性均较好，而半干旱地区（前郭）以NE方法相对较好。

Abstract

Based on 40 field experiments carried out in Yongji

Jiutai

Lishu and QianGuo counties of central Jilin province from 2013 to 2016

the application effects and applicability of two recommended fertilization methods (i.e. soil testing and formulated fertilization (ST)

and nutrient expert system (NE)) were compared by investigating grain yield

plant nutrient uptake

fertilizer use efficiency and apparent nutrient balance in one-season rice area. The results showed that the average rice grain yield was 9.17 t/hm2 in the farmer practice fertilization (FP) treatment

the average grain yield was 9.21 and 9.24 t/hm2 in ST and NE treatment

respectively

which were higher than that of FP

but there were no significant difference. The agronomic efficiency of nitrogen fertilizer in NE treatment was higher than that in ST treatment

and agronomic efficiency of phosphorus fertilizer in ST treatment was higher than those in FP and NE treatments

while there was no significant difference in agronomic efficiency of potassium fertilizer. Overall

no significant difference was observed in plant nutrient uptake and fertilizer recovery efficiency among the FP

ST and NE treatments. For the apparent balance of nutrients

soil nitrogen in three treatments all showed evident surplus

and the value followed the order of FP > ST > NE

while soil phosphorus and potassium showed slight and dramatical deficit

respectively. There were differences in the performance between different regions

the grain yield

plant nutrient uptake and fertilizer agronomic efficiency were relatively lower in ST treatment than those in NE treatment in Qianguo county

and this was different from the other three regions. In conclusion

both ST and NE methods showed well application effects on reducing fertilizer rate

maintaining high grain yield and increasing fertilizer use efficiency in the one-season rice area of central Jilin Province. The applicability of two methods were both well in semi-humid region (i.e. Yongji

Jiutai and Lishu)

however it was relatively better for NE than ST in semi-arid region (i.e. Qianguo).
