1、選種:選擇優良、抗病性強的種子。2、施肥:定期施薄肥,保持土壤中有充足的養分,提高植株的抗病性。3、澆水:生長期需要補充適量的水分,避免土壤缺水,影響植株正常生長發育。4、除草:定期清除土壤中的雜草,減少病蟲害的產生。

  種植白菜前,需要將土壤進行深翻,增加土壤的疏松性和透氣性,有利于植株扎根。土壤中需要施入適量的基肥,保持土壤肥沃。

  白菜的品種有好多種,所以它的種植時間一般在八月至九月初,都是在秋季種植。

  白菜適宜生長在冷涼的環境中,不同生長階段的白菜對溫度的要求不同,種子萌發時的最佳溫度為23℃左右,而白菜蓮座期的最佳溫度為17~22℃,養殖白菜時,如果環境溫度不適宜,就會導致植株的生長速度緩慢。
