不同收获方式对甘蔗农艺性状及产量的影响

Impacts of Different Harvest Methods on Agronomic Characters and Yield of Sugarcane

以勐海蔗区主栽品种粤糖03-393、粤糖93-159、新台糖16号、德蔗03-83为研究对象,调查这些品种机械收获和人工收获对宿根甘蔗农艺性状、产量和糖分的影响。研究表明:品种粤糖03-393机械收获后其株高、茎径、有效茎、单茎重、产量等均高于人工收获,糖分含量比人工收获的低近0.4个百分点;与人工收获相比,粤糖03-393机械收获的株高、单茎重和产量比其它品种增加幅度大,有效茎和茎径的增加幅度也排在第二。因此,在调查的4个品种中,粤糖03-393比较适合机械化收获。

This study investigated the effects of mechanical and artificial harvest for new planting sugarcanes Yuetang03-393, Yuetang93-159, Xintaitangl6 and Dezhe03-83 which were major planting varieties in Menghai area on agronomic characters, yield and sugar content of second year ratoon crop. The result showed that, plant height, stem diameter, productive tiller, stalk weight and yield of the sugarcane variety Yuetang03-393 by mechanical harvest were superior to that of artificial harvest, however, the sugar content by mechanical harvest was 0.4% lower than artificial harvest. Compared with artificial harvest, plant height, stalk weight and yield of Yuetang03-393 by mechanical harvest increased greatly than other varieties, which was also secondly increase of stem diameter and productive tiller. Conclusion： Yuetang03-393 was more suitable for mechanical harvest in the survey of 4 sugarcane varieties.
