On the manuring methods for direct sowing culture or rice plant in welldrained paddy field was investigated in relation to manuring time and space of fertilizer application.Additinal fertilizer application to deeper layer 5 and 15cm depth at 5 cm distance from hill at the panicle formation stage was more effective to the growth and yield. The chatacteristics of light-intercepting of rice plant was improved by the additional fertilizer application to deeper layer, so that percentage of productive clums and percentage of ripened grains were rised.Physiological effects of the fertilizer application to deeper layer were observed in root growth and activity. It was considered that many new root grew due the root cutting at the fertilizer application time and functioned till later growing period

本文研究了稻田直播施肥方法与施肥时间和施肥空间的关系，结果表明，在水稻成穗期距丘5cm处，深5和15cm处增施肥料，对水稻生长和产量有较好的效果。水稻深层增施化肥，改善了水稻植株的遮光特性，提高了成丛率和结实率，并对根系生长和活力产生了生理效应。认为施肥时断根导致大量新根生长，并一直作用到生育后期
