  水养富贵竹突然间叶子变黄通常是水质变坏或养分不足所产生的症状。   1.平时水培富贵竹要保持瓶水的干净,因水质不干净容易引起水质变坏,变坏的水里细菌多容易引起根部腐烂,腐烂的根系会影响水分和养分的吸收,水分的减少会产生叶片发软,养分的不足会出现叶片发黄,所以平时要换水来达到瓶水的干净,时常采用5-7天换一次水,每次换三分之二的瓶水量。   2.养分不足也会产生黄叶,每次换水后要往瓶中滴入营 养液,按每升6滴的量滴入,滴后要轻轻的摇荡瓶水使营养液充分的溶解在水中有利根系的吸收养分。   3.其它因素比如光线不足或病虫害,可摆放在室内向阳通风处减少徒长黄叶,病害可喷800-1000倍液多茵灵,虫害可用 湿布擦除。
