給花澆水,要注意“七多”與“七少”

發布日期:2019-03-22 瀏覽次數:59

對于新手花友澆花,一般會出現兩種情況。一種是由于對花草過于溺愛時不時的澆澆水,從而使花草由于水分過大被澇死。別一種則是由于疏于管理,經年累月的不管不顧連一滴水也不澆,從而導致旱死的。


以下是花卉澆水的“七多”與“七少”原則:

1、草本多澆,木本少澆

草本花卉根系淺,吸收水分能力差,體內需水量多,葉面蒸發快,故澆水應多而勤。木本花卉根系入土深,分布面廣,吸水力強,澆水量可適當少些。

2、濕生花卉多澆,旱生花卉少澆

龜背竹、吉祥草等濕生花卉應多澆水;仙人掌類、玉蓮花、南天竹等旱生花卉要少澆水。

3、葉大質軟的多澆,葉小有蠟的少澆

葉片愈大,質地愈軟,水分愈易蒸發,應多澆水;葉小有蠟質的花卉,葉面水分蒸發慢,可適量少澆。


4、沙質土多澆,黏質土少澆

沙質土疏松,保水性差,宜適當多澆水;黏質土緊實,保水性好,透氣性差,澆水不宜過多過勤。

5、天熱多澆,天冷少澆

天氣炎熱的盛夏酷暑,葉面水分蒸發量大,盆土干燥快,澆水要及時,要澆透。

6、天旱多澆,天陰少澆

天氣干旱,土壤容易失水,澆水要多而勤,小盆每日澆水2次,大盆每日澆水1次。

7、旺盛期多澆,休眠期少澆

花卉生長旺盛期時需要大量的養分和水分,故應結合施肥多澆水、勤澆水;花卉休眠期時,生長趨于停滯狀態,需水量很少,應嚴格控制澆水。
