简介：化肥氮(N)的高率在东南的中国在温室蔬菜地里被使用最大化生产；然而，如此的集中的蔬菜生产的N预算尚待被探索。这研究的目标是以五N(脲)应用程序率(0，348，522，696，和870kgNha1year1)在西红柿，黄瓜，和芹菜的年度旋转的一个温室蔬菜系统决定年度N平衡和损失。到050厘米土壤层的全部的N输入从531～1053kgha1，并且N化肥是主要N来源，为全部的年度N输入的66%83%的财务。在比较，总共的灌溉水，湿免职，和种子占了不到1%全部的N输入。化肥N使用效率仅仅在870kgNha1的常规申请率下面是18%并且当申请率从522～870kgNha1增加了，减少了。明显的N损失是196201kgNha1，71%86%被以522870kgNha1的申请率沥滤失去。因此，沥滤是以高N申请率的主要N损失小径，N的数量沥滤与在黄瓜季节期间使用的N成正比。而且，溶解器官的N说明了10%沥滤的N，而NH3挥发仅仅在五N下面贡献了明显的N损失的0.1%0.6%，申请在这个温室蔬菜系统评价。

简介：在东南亚洲的蔬菜生产经常是依次与充满的米饭。有充满的大米生产的土壤的puddling可以为干燥土地庄稼的随后的生产导致不利土壤条件。为了证实永久蔬菜生产是否导致赞成土壤，在充满的大米在一个2年的地实验被学习以后，在土壤性质上与充满的大米依次为蔬菜，五个不同永久蔬菜生产系统的效果和蔬菜生产的一个系统调节。在0.05–0.10m深度层的体积密度与充满的米饭依次与永久蔬菜生产和蔬菜生产减少了。减少大批，密度被器官的粪肥和米饭外壳的申请影响，并且特别由庄稼的数字栽培了建议土壤耕种的那频率穿上主要效果体积密度。在在有提起的床的建设的联合，充满的米饭能在土壤结构上减少或完全消除puddling的否定效果以后，与公牛拖拉耕作。在0.15–0.20m土壤深度的体积密度没被影响。土壤酸味在所有系统显著地减少了。器官的碳在所有系统增加了的土壤，而是重要增加仅仅在二个永久蔬菜生产系统被发现。可得到的磷(P)显著地在二个永久蔬菜生产系统增加了，与一断然，到P的数量的关联适用。重要减少大批在pH的密度和增加(H2O)在仅仅2年以后，证明在充满的米饭以后的土壤条件能在集中的蔬菜下面在一短时间被改进生产。
