石榴全世界的溫帶和熱帶都有種植,中國湖北、貴州、廣西等地都可以栽種石榴。石榴適宜栽種在疏松、透氣、肥沃排水性好的沙質土壤中,喜歡溫暖、向陽的生長環境,不耐澇和過于蔭蔽的環境,石榴適宜生長溫度是15~20℃,當外界溫度低于-18℃時,植株會受到凍害。

  石榴的介紹

  石榴地栽每年須重施一次有機肥料,盆栽1年至2年需換盆加肥。在生長季節,還應追肥3次至5次,并注意松土除草,經常保持盆土濕潤,嚴防干旱積澇。

  石榴進入結果期后,需對徒長枝進行夏季摘心和秋后短截,避免頂部發生二次枝和三次枝,使其貯存養分,以便形成翌年結果母枝,同時還要及時剪掉根際發生的萌蘗。

  石榴樹從4月底到5月上、中旬易發生刺蛾、蚜蟲、蝽象、介殼蟲、斜紋夜蛾等害蟲;坐果后,病害主要有白腐病、黑痘病、炭疽病。
