【摘要】 分析了川蔗23号的丰产性、稳产性及产量构成。结果表明,川蔗23号的丰产性突出、稳产性较好。产量构成3要素中,公顷有效茎对产量的效应最大,茎径次之,株高作用最小。在高产栽培上,以公顷有效茎8．9-10．5万条,株高255-285cm,茎径2．8-3．1cm为最合理的高产群体结构。更多还原

【Abstract】 The high yielding potential, yield stability and the yield component traits of Chuanzhe 23 were analyzed. The results showed that Chuanzhe 23 was high yielding with excellent yield stability. Among the 3 characters, the millable stalks per hectare contributes most to the yield, the diameter was secondary in the effect of yield, and the stalk height was the least. In high yielding cultivation, it is the most rational with 89000-105000 stalks/hm2 in millable stalks, 255-285 cm in stalk height, and 2.8-3.1 cm in stalk diameter.更多还原
