摘　　要：对第一、二代巴西蕉的钾、镁、硫肥配施技术进行研究。比较了不同施钾水平及钾、镁、硫肥配施对香蕉营养生长、抽蕾、蕉果农艺性状、产量及种植利润的影响,提出两代高产巴西蕉的适宜氮钾肥用量,并指出在土壤镁素丰富的情况下(即使土壤Mg/K仅为1.37),可以不考虑镁肥的施入。Application technologies of K, Mg and S for the first and second Baxi banana plant were studied. The vegetative growth, floral emergence, fruit's agronomic characteristics, fruit yield and plantation efficiency of different fertilizer combinations including K, Mg and S were compared. Proper use rates of N and K were recommended for two generation Baxi banana, and it was pointed out that if soil was rich in Mg and the ratio of Mg/K was even low to 1.37, Mg was not necessary to be used in banana's production.
