| 摘 要： | 目的]研究不同供水量与施磷量对甘蔗经济性状的耦合效应.方法]以广西甘蔗品种新台糖22号(ROC22)为材料,通过供水量设置3个水平,在甘蔗分蘖初期至伸长末期,每旬供水量分别为199.5m3/hm2(A1),400.5 m3/hm2(A2)、600.0 m3/hm2(A3);磷肥施用量设置4个水平,作为基肥分别施用P2O5 0 kg/hm2(B1)、120 kg/hm2(B2)、240 kg/hm2(B3)、360 kg/hm2(B4),来研究不同供水水平与磷肥水平组合处理对甘蔗产量和品质性状的影响.结果]处理A2B2为较适合提高甘蔗经济性状的水磷配比处理.结论]该研究结果为广西甘蔗生产中的水分、磷肥高效利用及甘蔗高产、高糖栽培提供理论依据.
Abstract：
Objective] The aim was to study the coupling effect of water and phosphate on economic traits of sugarcane.Method]Taking sugarcane variety ROC22 as tested material,coupling effects of different levels of water supply quantity and different levels of phosphorus fertilizer on the yield and quality of sugarcane were studied.Among them,water supply quantity had 3 levels,that was,the water supply quantity per 10 days from the early tillering stage of sugarcane to the end of elongation was 199.5 m3/hm2 (A1),400.5 m3/hm2 (A2) and 600.0 m3/hm2 (A3),respectively;Phosphorus fertilizer as basic fertilizer had 4 levels:P2O5 0 kg/hm2 (B1),120 kg/hm2 (B2),240 kg/hm2 (B3) and 360 kg/hm2(B4). Result] Treatment A3B2 in water-fertilizer coupling was more suitable to improve economic traits of sugarcane. Conclusion] The research results provide theoretical basis for the efficient utilization of water and phosphorus fertilizer in production of Guangxi sugarcane and the cultivation of high-yield and high-glucose sugarcane.
