　　我們平日吃甘蔗都是看到一根根粗壯的莖稈，但是很少看到甘蔗開花的，也沒聽說過甘蔗有種子的，許多地方種植甘蔗也都是選用成熟甘蔗的尾部進行插土發芽，那么甘蔗有種子嗎?如果沒有成熟甘蔗種植，甘蔗又怎么來?下面果果來和大家一起了解一下吧!

　　甘蔗有種子嗎

　　甘蔗是有種子的，但是一般種植甘蔗都不采用種子。
甘蔗有種子嗎 甘蔗有種子在特定地區可以開花

　　為什么看不到甘蔗的種子?因為甘蔗只有在南北緯10°左右的熱帶地區才比較容易開花結果，緯度高或者低都不易開花，在我國更是少數，除了海南省南部、云南的瑞麗地區中的特殊品種之外，基本上不會存在甘蔗開花。甘蔗一般也不會孕穗抽笞，即使孕穗抽笞也不會開花結實。

　　甘蔗的種子在哪里呢?

　　甘蔗的花是由植株頂部生長點通過光周期后進行花芽分化，為花錐花序。一個花穗上有小穗8000～15000個，每個小穗有1粒子實，甘蔗的種子(其實為果實，但種皮和果皮不易分離)為穎果，極小，大約1.5×0.5mm。

　　為什么種植甘蔗不用種子了?

　　甘蔗如果采用種子種植，那么生長周期大約需要18個月左右，并且甘蔗種子在不同地區的發芽率也不同，對于大批量規模種植的人來講并不是最好的選擇，如果采用成熟甘蔗桿進行發芽種植，發芽率高，并且種植簡單，最主要的是生長周期只需要10~12個月即可，生長周期是大大縮短，獲利也大大提升。

　　甘蔗怎么種植

　　如今甘蔗種子都采用莖稈發芽的方式，并且種植方法也更系統、先進。

　　1、選用甘蔗尾巴

　　甘蔗尾部的芽最密，而且甘蔗尾巴抗旱性好，病蟲害少，并且甘蔗尾巴的活力好，對于濕潤土壤也不會受到很大的影響，甘蔗尾巴生長出的幼苗也多。

　　2、選擇甘蔗全身

　　如果想讓甘蔗生長的速度比較快，幼苗粗，那么久選擇第一年的甘蔗全身來作為甘蔗的種，但這種甘蔗苗沒有甘蔗尾部培育出來的幼苗多。

　　現在甘蔗種植的方法也多樣化，講究“深耕、淺種、寬行、密植”，詳細方法可以繼續了解：甘蔗怎么種!
