Abstract
In order to research the relationship of double layer's source-sink for both the photosynthetic production and the mineral nutrient, two types of soil environmental treatments, narrow bed with dense ditchs and level paddy field, and three level's nitrogen application, 0 kg N/ha, 150 kg N/ha, 225 kg N/ha, were designed. The development and distribution of rice root system play a role in forming a connecting link between photosynthetic source-sink and mineral nutrient source-sink. The improvement of soil water environment may promote the development and extending downward of rootsystem, mineralization of soil N, and N absorption of plant simultaneously.The efficiency of absorption of applied N increases with the N absorbing ability of the plant, it is necessary to increase the utilization efficiency of absorbed N for further increasing the yield efficiency of applied N. It is important to improve the population structure of canopy in order to obtain a harmonious development of double layer's sourcesink.
