[目的]探讨粉垄栽培甘蔗的增产机制,为粉垄甘蔗生产提供理论依据。[方法]以甘蔗品种桂糖43号为试验材料,研究粉垄耕作栽培和传统耕作栽培对甘蔗生长和产量的影响。[结果]粉垄栽培有利于提高甘蔗的出苗率和分蘖率,粉垄甘蔗的出苗率比对照增加20.7%,分蘖率比对照增多25.4%;粉垄甘蔗的月生长速度比对照快6.4%~53.7%;蔗茎增粗7.7%~23.8%;粉垄蔗茎产量为191.25 t/hm~2,比对照增产18.2%。相关分析显示,有效茎数、茎长和茎径3个性状对蔗茎产量影响由大到小为茎长、茎径、有效茎数。[结论]粉垄栽培是一项适宜甘蔗优质高产生产的新技术,可加以推广普及。 [Objective] The research aimed to discuss the mechanism of increasing production of sugar cane in Fenliu ridge and provide the theoretical basis for the production of Fengyan sugar cane. [Method] The sugarcane variety Guiguang 43 was used as experimental material to study the effects of powder ridge cultivation and traditional tillage cultivation on the growth and yield of sugarcane. [Result] The cultivation of powder ridge was beneficial to increase the emergence rate and tillering rate of sugarcane. The emergence rate of sugarcane in Fenren increased by 20.7% and the tillering rate increased by 25.4% compared with the control. The monthly growth rate of sugarcane in Fenren was 6.4% 53.7%; cane stems increased by 7.7% ~ 23.8%; pollack cane stems yield was 191.25 t / hm ~ 2, 18.2% more than the control. Correlation analysis showed that the effective stem number, stem length and stem diameter of three traits on the cane yield from big to small stem length, stem diameter, effective stem number. [Conclusion] Cultivation of powder ridge was a new technology suitable for high quality and high yield of sugarcane production, which could be popularized and popularized.
