摘　　要：本文以调查问卷的形式,对吉林省水稻综合生产能力、科学施肥技术水平、测土配方施肥等一些问题作了细致的调研。通过分析调查110个农户的数据,结果表明:吉林省在氮磷钾肥料施用上存在不合理现象,氮肥普遍施用量过高,而磷钾肥施用则明显不足,最适宜施肥范围农户仅占17%。从施用肥料的偏生产力看,水稻磷钾肥的偏生产力过低,氮肥的偏生产力也有待提高。In this paper,we made a careful investigation of rice production capacity,science and technology level and some problems such as soil fertilizer based on the questionnaire in Jilin Province.Through analysis of the data of 110 farmers,the results showed there was an unreasonable phenomenon in the use of NPK fertilizers.The quantity of nitrogen fertilizer is too high,but the quantity of phosphate and potash fertilizer is considerably low.The most appropriate application of fertilizer only account for 17% of farmers.The rice yield increase of phosphate and potash fertilizer was too low,and rice yield increase of nitrogen could also be raised.
