一、未结果幼树施肥
幼树在试花前，主要是促进营养生长，及早形成树冠和骨架。因柑橘每年抽发三次新梢，应重施3次促稍壮梢肥，即2月下句至3月上旬施春梢肥，5月上、中旬施夏肥梢，7月中、下旬施早秋梢肥。肥料以腐熟人畜粪、尿素、巴内达碧卡复合肥等速效肥为主。因幼树根系范围小，吸肥能力较差，宜勤施薄施。在投产前一年秋季增施磷钾肥，例如巴内达碧卡磷酸二氢钾，以利花芽分化。
二、初结果幼树施肥
初结果柑桔幼树的施肥既要有利于扩大树冠又要使其逐年增加产量。初结果幼树的施肥一般分花前肥，在2月份施用。壮果促梢肥，宜在7月中下旬施。复壮肥宜在采果一周前后及时施。花前肥占全年施肥量的30%，壮果促梢肥占全年施肥量的40%，复壮肥占全年肥量的30%。以氮、磷、钾肥配合施用。
