摘要
研究了广东省几个主栽甘蔗品种的肥料效应，提出广东省甘蔗专用BB肥的适宜配肥比例为N：P2O5：K2O=1：0．30：0．78-1．00．在中等肥力土壤上，高产甘蔗推荐施肥量为甘蔗专用BB肥1140-1410kg/hm2.施用甘蔗专用BBe肥具有极显著的增产效益，其肥效优于通用型复合肥（15-15-15）和当地肥料，单位面积投肥成本低，经济效益高．
On the basis of the results,a nutrient formula, N: P2O5: K2O = 1: 0.30: 0.78 ~ 1.00 , was created formanufacturing sugarcane-specific bulk blending fertilizers (BBF) in Guangdong province. The recommending rates ofBBF should be 1 140 ~ 1 410 kg/hm2 for high-yield sugareane on soils with medium fertility. Sugar-specific BBF isvery significantly superior to compound fertilizers (15-15-15) and local fertilizers. In addition, BBF can also reducefertilization cost, thus increasing production profit.
