中文摘要	对平作表层土层施肥与垄作表层，中层，底层，土层施肥时的小麦不同生育时期各器官含Ｎ量的研究结果表明：无论是垄作还是平作表层施肥，小麦从三叶期到拔节期根，叶的含Ｎ量由高到低，而垄作中层和底层施肥却由低到高。三叶期时根，叶含Ｎ量以表层施肥－中层施肥－底层施肥。
英文摘要	This study the Nitrogen content of wheat organs in different growing periods was carried out in fertilizer opplications (flat planting application at 1 - 2cm in soil layer depth, and mound planting application at 1-2cm,25cm,45cm in soil layer depth). The conclusions were drawn as follows :from three-leaves period to shooting period,the Nitrogen content of wheat’ s roots and leaves is ranged from high to low for the surface application of both planting methods; but the case was just contrary for the middle layer and the bottom layers applicaation of mound planting application. In the three leaves period, the Nitrogen content of wheat’ s roots and leaves was increased by the surface application much or considerably more than by the middle layer application. The same result can be gotten between the middle layer application is compared with the bottom layer application. However, there is no obvious difference of Nitrogen content of wheat’ s roots and leaves for the surface application of both planting methods. For the wheat plants in three leaves period and growth period after wards, different application methods have no notable influnce on the Nitrogen content of the roots, stems, leaves, grains and shells.
