點解追肥後要十日後才可收割

各位:

點解追肥後要十日後才可收割?

我都想知道哦!!

Gender,
What fertilizer are you using ?
Some said the harvest's not good for health after fertilizing. (of course, I also want to know the exact reason).
I wonder if it's related to virus in the fertilizer as most of them are bird/cow/goat faeces.

其話無話一定要10日,不過唔好一施完就收,一來無作用,二來無記錯係因為硝酸鹽問題
esp葉菜.
睇下大家有無其他意見~

多謝owlcyr的解答.
