原因1:土壤碱性化缺铁 解决方法:生长期每7~10天浇一次含0.2%硫酸亚铁水或者施一次矾肥水,也可两者相间进行,这样既能够防止土壤碱性化,还可补充土中的铁质,从而防止叶片发黄,并能使叶片油光发亮,花朵肥大。 原因2:黄化病 解决方法:栀子花容易发生黄化病和叶斑病,可以用65%代森锌可湿性粉剂600倍液喷洒防治。 栀子花养花技巧: 土壤:适宜用含腐殖质丰富、肥沃的酸性土壤栽培,一般可用3:2:5的腐叶土、沙土、园土混合配制栽培。 温度:生长期适温18~22℃,越冬期可在5~10℃良好生长,低于-10℃则容易出现冻害。 光照:栀子花属于半阴性植物,所以在保证有阴凉环境的同时,还要保持全天60%的光照,以满足其生长的能量需求。 水分、湿度:栀子花在幼苗期要注意浇水,使盆土保持湿润。浇水宜用雨水或者经过发酵的淘米水。 花期:5~8月 果期:10月
