我国水稻氮肥高效利用的研究进展
Progress of study on rice nitrogen efficient utilization in China
摘要
Abstract
This paper reviews the present situation and main problems of rice nitrogen fertilizer use efficiency in Chi -na.Analysed the possible reason of low rice nitrogen utilization in China from four aspects which were application of high yielding rice and high soil nitrogen background content ,unreasonable fertilization time and proportion ,mid-time fielddry-ing.And puts forward several method such as selecting rice varieties with high nitrogen utilization rate ,the application of the new type of nitrogen fertilizer and improved fertilization technology , balanced fertilization , the use of urease inhibitor and nitrification inhibitor , adopted properly nitrogen fertilizer management and water -fertilizer control technique to im-prove the utilization rate of nitrogen fertilizer on rice.关键词
