摘要
[目的]了解广东省恩平市早稻种植生产过程中施肥管理中存在的问题,为早稻平衡施肥提供参考。[方法]通过农户抽样调查,对恩平市18户(样本)早稻种植户早稻施肥状况进行分析。[结果]广东省恩平市早稻生产中施肥次数为1~3次,施用肥料以颗粒复合肥料(15-15-15)为主,用尿素、过磷酸钙、氯化钾补充氮、磷、钾,未施用有机肥。氮(N)、磷(P_2O_5)、钾(K_2O)的平均施用量分别为192.36、62.75、132.92 kg/hm^2,肥料施用比例N∶P_2O_5∶K_2O=1.00∶0.33∶0.69。[结论]广东省恩平市早稻生产中肥料施用量偏高,特别是氮肥投入偏高,忽视有机肥和基肥。
[Objective] The paper is to understanding the problems of local fertilization management of early rice planting in Enping City,and provide some references for balanced fertilization of local early rice production. [Method] Through investigating,fertilization status of 18 early rice planters in Enping City were analyzed.[Result] The number of fertilizer used in early rice production in Enping City was 1-3 times;the main species was compound fertilizer （ N ：P：K = 15：15：15 ）, using urea, superphosphate, potassium chloride as supplement, no organic fertilizer.Average amount of N, P2O5, K2O fertilizer were 192.36 kg/hm^2, 62.75 kg/hm^2 and 132.92 kg/hm^2, respectively, and N ：P2O5 ：K2O = 1.00：0.33：0.69. [Conclusion] In the early rice production in Enping City, fertilizer application rate is high, especially nitrogen fertilizer, organic fertilizer and base fertilizer were ignored.
