摘要
Abstract
The interactions of water management and nitrogen fertilizer on nitrogen absorption and utili-zation were studied in rice with Wuxiangjing9 (japonica). The results showed that the nitrogen uptake and re-maining in straw increased and the percentage of nitrogen translocation (PNT) from vegetative organs, nitro-gen dry matter production efficiency (NDMPE) and nitrogen grain production efficiency (NGPE) decreasedwith nitrogen increasing. The nitrogen uptake and NGPE decreased when severe water stressed. However, ricenot only decreased the nitrogen uptake but also increased the PNT from vegetative organs, NDMPE and NGPEwhen mild water stressed. There were obvious interactions between nitrogen fertilizer and water management,such as with water stress increasing the effect of nitrogen on increasing nitrogen uptake was reduced and thaton decreasing NDMPE was intensified.关键词
