| 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,将供水量设置3个水平,即在甘蔗分蘖初期至伸长末期,每旬供水量分别为199.5（A1）、400.5（A2）和600.0 m3/hm2（A3）;磷肥施用量设置4个水平,即作为基肥分别施用P2O50（B1）、120（B2）、240（B3）和360 kg/hm2（B4）,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的水磷配比为较适合提高甘蔗经济性状。结论]该研究为广西甘蔗生产中水分和磷肥的高效利用及高产高糖甘蔗栽培提供了理论依据。

| 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(A1),400.5(A2) ... |
