四、宿根蔗的收獲

收獲期30天前停止灌水、施肥,如遇連續干早天氣除外。同時,蔗莖田間錘度達20,蔗糖分達14.00%以上時,則可以進行砍收。收獲順序:1、可按品種的熟性,早熟品種中熟品種一晚熟品種;2、可按植期:秋植蔗宿根蔗一冬植蔗春植蔗。但要留宿根的蔗地最好于春暖氣溫回升即1月份以后砍收最適宜。砍收的方法是:用鋒利小鋤低砍,入土2-5厘米最好。低砍既可增加產量,又能促進低位芽萌發。或采用切段式或整桿式甘蔗收獲機進行機械化收獲。因宿根蔗苗粗苗壯,在人工砍收時,要避免砍裂蔗頭,損壞蔗芽。同時,原料蔗砍收應符合GB/T 10498的要求。蔗梢削去生長點以下30cm;蔗莖不帶混、須根和葉鞘及其他夾雜物;枯死蔗莖和1米以下的蔗筍不能作為原料蔗。
