| 摘 要： | 氮肥对作物的增产效果,决定于作物对氮肥的吸收率(即氮肥的利用率)和作物体内累积的氮素转化成经济产量的效率。水稻对氮肥的利用率一般显著低于旱作,未被吸收利用的部分从土壤中的损失一般也较旱地多。

| Abstract: | The present article deals with the patterns of soil N the uptake of soil and fertilizer N by rice plant and the fate of fertilizer N in relation to the forms and methods of placement of N fertilizer in the paddy soils of Suchow District, Jiangsu Province. Field experiment was carried out with 15N-tracer technique. The soils used for the experiment are developed from the alluvial-lacustrine deposits with a feature of clay loam. |
