摘要[目的]Y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、***化钾补充氮、磷、钾,未施用有机肥。氮(N)、磷(P205)、钾(K20)的平均施用景分别为192. 36、
62. 75、 kg/hm2,肥料施用比例 N : P205 : K20=l. 00 : 0. 33 : 。[?Y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。

Abstract [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 pound fertilizer (N : P : K =15:15: 15),
using urea, superphosphate, potassium chloride as
