Other Abstract通过田间小区试验, 研究了川中丘陵地区紫色土垄作表施(垄面下1~2cm土层处施肥)、垄作中施(垄面下25cm 土层处施肥)、垄作底施(垄面下45cm 土层处施肥) 和平作表施(常规耕作的1~2cm 土层处施肥) 对小麦-土壤生态系统中氮素平衡的影响。结果表明, 在小麦生长期不同处理向土壤中增加了氮素103.14~133.62kg/ha, 土壤中的氮素增加量差异表现为平作表施< 垄作底施< 垄作中施<垄作表施, 其变化趋势与小麦产量和吸氮量相反。 
; By means of an experiment on the effect of the nitrogen balance in wheat soil ecological system under ridge culture condition with different depth fertilization (1 2,25,45cm under ridge and soil surface fertilization without ridge culture) as control were conducted in hilly field in the middle of Sichuan provice.The results showed that the addition of N was 103 14~133 62kg/ha in soil at the whole growth stage of wheat in different treatments. The change of the addition of N in soil was in the order:surface layer fertilization(1~2cm) without ridge
