摘要
ＢＢ（ＢｕｃｋＢｌｅｎｄ）肥是按不同作物所需养分配制成的专用肥料，具有浓度高，加工简单，成本较低，运输方便，施用简便等优点。本试验选用质量分数ω＝５０％水稻型ＢＢ肥与质量分数ω＝３５％的全元肥（复合肥）和常规施用的单质化肥（碳铵，钙镁磷，氯化钾，尿素）以相等价格投入作对比试验，ＢＢ肥在水稻生育和产量上明显优于其他两种用肥。
BB(Buck Blend) fertilizer is a high-concentration, low-cost, convenient and simple special fertilizer prepared on the basis of plant biological character and balance fertilizing. The field experiment on 50% of BB fertilizer, 35% of fixed fertilizer and conventional fertilizers (ammonium carbonate, serpentine-fused phosphate, muriate of potash, urea) for rice was carried out. The results showed that the BB fertilizer can increase rice yield obviously at the same cost.
