The study was conducted through investigation and analysis of the rotation system, fertilization, grain yield and returning of stalk to the field in the suburbs of Yuanjiang city. In rice soil the input of N and P was grossly balanced with the output of N and P but the input of K was not adequate. In ramie soil P and K were balanced on the whole but there was surplus N. The contents of soil organic matter and tatal N were lower in ramie soil than in rice soil and N hydrolysed by alkali and available P, K were...

The study was conducted through investigation and analysis of the rotation system, fertilization, grain yield and returning of stalk to the field in the suburbs of Yuanjiang city. In rice soil the input of N and P was grossly balanced with the output of N and P but the input of K was not adequate. In ramie soil P and K were balanced on the whole but there was surplus N. The contents of soil organic matter and tatal N were lower in ramie soil than in rice soil and N hydrolysed by alkali and available P, K were higher in ramie soil than in rice soil. Excessive N and P in rice and ramie soils also had in-fluence on the balance and availability of soil K and Zn.

通过对沅江洞庭湖区稻田、麻园土壤生态系统的轮作制度、施肥情况、作物产量及秸杆还田的调查分析,研究了湖区不同土壤生态系统的养分平衡状况,结果表明:湖区稻田土壤生态系统的氮素、磷素输入输出基本平衡,钾素严重亏缺,麻园土壤生态系统氮索盈余,磷素、钾素基本平衡,因有机质矿化作用较强,土壤有机质和全氮含量比稻田土壤偏低,而碱解氮和有效磷、钾养分高于稻田稻田土壤。同时,稻田、麻田土壤大量施用氮、磷肥,也影响到钾素及微量元素锌的平衡和有效性。

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

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。
