白菜最低在-2℃的時(shí)候收獲。白菜喜歡冷涼的生長(zhǎng)環(huán)境,耐低溫,當(dāng)外界溫度在零下的時(shí)候,白菜也能生長(zhǎng),但若是氣溫在-8℃時(shí),植株會(huì)受到凍害,需及時(shí)收獲。白菜不耐高溫,在高溫的環(huán)境中,白菜易產(chǎn)生病蟲(chóng)害,影響白菜的產(chǎn)量以及品質(zhì)。

  白菜的種植

  種植白菜需要選擇保肥、保水并富含有機(jī)質(zhì)的壤土與砂壤土及黑黃土中,在容易漏水漏糞的砂土和排水不良的粘土中生長(zhǎng)不良,種植白菜之前,需將土壤深耕,并且還需要在土壤中施加足量的有機(jī)肥,促進(jìn)植株生長(zhǎng)。

  白菜出苗后5~6天需進(jìn)行第1次間苗,去弱留強(qiáng),條播的留苗間距2~3厘米;大白菜3~4片葉時(shí)進(jìn)行第2次間苗,條播地塊的苗距8厘米,穴播時(shí)每穴留3株左右;再過(guò)5~6天時(shí)進(jìn)行第3次間苗。白菜生長(zhǎng)期需進(jìn)行3次中耕,分別在第2次間苗后、定苗后和蓮座中期進(jìn)行。
