宿根甘蔗栽培性状的研究

Study on the Growth and Yield Characters of Ratoon on Dry Farm Land

本文研究了宿根蔗栽培性状及产量结构特点,结果表明宿根蔗具有发株早、生长快、成熟早、榨季早期蔗茎较长的优势。指出宿根蔗低产的主要原因首先是有效茎数少,其次是蔗茎较短。还重点分析了ROC16和ROC222品种的蔗茎生长、苗数消长动态及产量结构的特点,并提出相应的高产稳产栽培技术措施。

Ratoon cultivation characters and yield component was studied. Results showed that ratoon had the advantages of early growing, early maturing and longer stalk in early grinding season. It was the fewer millable canes first, then the shorter stalk that caused low cane yield for ratoon. The stalk growth, shoot number changing and cane yield component of ROC16 and ROC22, the two new leading cultivars, were analyzed, and the corresponding cultivation measures were also discussed.
