春季油菜花需要注意做好保暖措施、及時補水、提供養分。將環境溫度控制在15~20℃之間,避免植株被低溫凍傷,影響植株正常生長發育。灌溉充足的水分,保持土壤濕潤,但不能積水。定期施薄肥,保持土壤中有充足的養分,促使植株茁壯生長。

  油菜花耐熱不耐寒,因此不適宜北方栽種,分布的大部分地區都是在西南地區,養護溫度要保證在20℃以上,它就可以正常生長。冬季需要做好保暖措施。

  油菜花喜濕潤,生長期需要勤澆水,保持土壤中有充足的水分。溫度比較高的時候,水分蒸發快,需要兩天澆水一次。澆水時少量多次,避免土壤積水。

  在油菜薹花期,每隔一定時間噴1次磷、硼、錳等微量元素或復合有機肥的水溶液,可防止油菜花而不實。
