那麼，怎樣才能減輕氯離子對柑桔的危害呢？一是增施氮肥，少施或不施鉀肥。一般株產50公斤的桔樹可施尿素0.3公斤左右，再加40~50公斤的腐熟人糞尿水，在施用複合肥時，一定要選用含氮量高而含氯化鉀量低的品種，目前的複合肥大都是尿素－過磷酸鈣－氯lv化hua鉀jia係xi列lie的de複fu合he肥fei，有you的de在zai其qi中zhong再zai加jia入ru了le氯lv化hua銨an。因yin此ci，它ta們men中zhong含han有you高gao量liang的de氯lv離li子zi，容rong易yi對dui桔ju樹shu造zao成cheng毒du害hai。二er是shi氯lv化hua鉀jia不bu宜yi作zuo根gen際ji施shi肥fei，更geng不bu要yao用yong作zuo葉ye麵mian施shi肥fei，根gen際ji施shi用yong時shi，最zui好hao選xuan用yong硝xiao酸suan鉀jia、硫酸鉀或磷酸二氫鉀。作葉麵肥施用時，可用尿素、過磷酸鈣、磷酸二氫鉀（或硝酸鉀）加水後倒入缸內，漚製5~7天後再取其濾液，用清水稀釋後用於葉麵噴施，噴布後能使葉色轉青、葉片增厚，壯果效果好，以後秋梢受凍明顯減輕，落葉較少，翌年花質和花量都明顯提高，且能有效地防止氯離子對柑桔的毒害。
