粉垄栽培甘蔗试验增产效果

 【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。

Yield Increase of Smash-Ridging Cultivation of Sugarcane

【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.
