粉垄栽培甘蔗试验增产效果

摘要

[目的]评价粉垄栽培技术相比于传统栽培方法种植甘蔗的优势所在.[方法]选用新台糖22号和柳城03-1137两个品种,在不同地区进行粉垄栽培和传统栽培比较试验,在甘蔗工艺成熟期进行根系、绿叶、蔗茎性状、产量、品质及冬笋芽数等调查测定.[结果]粉垄栽培与传统栽培相比,根系鲜重增加了115.05％-146.48％;完全展开绿叶数(功能叶片)增加14.65％-19.35％;蔗茎产量增加21.91％-27.35％;甘蔗蔗糖含量、蔗汁蔗糖含量分别增加3.81％-5.17％、3.63％-5.75％,蔗汁还原糖分降低5.50％-9.76％;宿根冬笋芽数增加47.64％-197.70％.[结论]粉垄栽培的甘蔗,根系特别发达,功能叶片数增加,产量提高,品质改善,冬笋芽数增加.粉垄栽培方法是一项较好的栽培新方法.%[Objective] The objective of the experiment is to compare the effect of smash-ridging cultivation of sugarcane on yield increase with traditional cultivation method and to provide a basis for the smash-ridging cultivation of sugarcane. [Method] Sugarcane varieties ROC22 and Liucheng 03-1137 were planted in different places by smash-ridging and traditional cultivation methods, and the roots, green leaf, cane stem characters, yield, quality, bamboo shoots buds number and so on were measured. [Result] Compared to traditional cultivation, sugarcane cultivated with smash-ridging method, the fresh weight of roots increased by 115.05%-146.48%, the number of complete expanded green leaf (functional leaves) increased by 14.65%-19.35%, the cane stem products increased by 21.91%-27.35%, the cane sucrose contents and juice sucrose contents increased by 3.81%-5.17% and 3.63%-5.75%, respectively, juice reducing sugar contents reduced by 5.50%-9.76% the bamboo shoots buds number increased by 47.64%-197.70%. [Result] Planting sugarcane by smash-ridging promoted the development of roots, increased the functional leaves, improved yield, and quality, and increased the bamboo shoots buds number.
