向日葵九月份會開花,雖然向日葵的花期在7~8月,且9月已經(jīng)是它的種子成熟期,但如果種植比較晚,花期也會適當(dāng)延遲,因此有的向日葵九月也仍在開花。不過養(yǎng)殖向日葵時,使用積溫的方式,使其在生長的過程中積累一定的溫度,就可以一年四季開花,如果種植比較晚,那花期也會適當(dāng)延遲。

  向日葵的介紹

  向日葵又名朝陽花,因其花常朝著太陽而得名,高1~3.5米,在陽光充足,潮濕或受干擾的地區(qū)生長最好,世界各國和中國均有栽培,通過人工培育,在不同生境上形成許多品種,特別在頭狀花序的大小色澤及瘦果形態(tài)上有許多變異,并為綜合利用的最好原料。

  向日葵的生長期是指從出苗到種子成熟所經(jīng)歷的天數(shù),一般為85~120天以上,向日葵整個生長期分為幼苗期、現(xiàn)蕾期、開花期和成熟期四個生長時期。

  向日葵對土壤要求較低,在各類土壤上均能生長,從肥沃土壤到旱地、瘠薄、鹽堿地均可種植,可以在堿性土壤中茁壯成長,抗旱性較強。
