在考虑土壤肥力、甘蔗营养特性的基础上，研制出含有改性配方稀土、甘蔗滤泥和氮、磷、钾的甘蔗专用肥。３年９个大田试验的平均结果表明：甘蔗施用含稀土有机复混肥后，平均产量为８８ ６８０ ｋｇ／ｈｍ２，平均田间锤度为 １９． ８％，理论产糖量平均为 １０ ５３０ ｋｇ／ｈｍ２，比不含稀土，但含等量氮、磷、钾、有机质的有机复混肥增产 ８ ４１５ ｋｇ／ｈｍ２，增产率为１０．５％，田间锤度提高１％，增糖１６．４％。
On the basis of soil fertility and nutrition characteristics of sugarcane, sugarcane special fertilizer containing modified formula rare earth, sugarcane filter mud and nitrogen, phosphorus and potassium was developed. The average results of nine field trials in three years showed that the average yield of sugarcane after applying organic compound fertilizer containing rare earth was 88 680 kg / hm2 and the average field brix was 19. 8%. The theoretical yield of sugar is 10 530 kg / hm2, which is 8 415 kg / hm2 higher than that of organic compound fertilizer containing no nitrogen, phosphorus, potassium and organic matter. The rate of yield increase is 10.5% , Field brix increased by 1%, 16.4% increase in sugar.
