【摘要】 采用特殊配方的粒状甘蔗专用肥及深施技术，经大田对比试验结果表明：在Ｎ、Ｐ比例一致条件下，粒肥比常规施肥，Ｋ的含量可减少，且施肥总量可降低７５０ｋｇｈｍ－２，节约肥料成本２５％，而经济产量差异不大．从而为甘蔗科学施肥提供一定的依据更多还原

【Abstract】 The field contrast experiment with granulated fertlizer of particular formulation spesific to sugarcane buried in the soil was carried out to indicate that, compared with the native fertilization at the same ratio of N,P, buried granulated fertilizer could decrease application K and the total fertilizer by 750 kg·hm -2 , save the total fertilizer cost by 25%, however no significant differences in economic yield were found among treatments. It will provide the evidences for scientific fertilization in sugarcane.更多还原
