含稀土有机复混肥的研制及其在甘蔗上的应用研究

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％。

Application study on rare-earth-containing organic compound fertilizer specialized for sugarcane

A rare - earth - containing organic compound fertilizer was made based on soil fertility and nutrient character of sugarcane, which contains rare earth, bagasse and nitrogen, phosphorus potassium. A3 - year - 9 time field experiment result shows that the sugarcane yield is 88 680 kg/hm2, field sugar hammer degree is 19. 8%, cane sugar yield of theory is 10 530 kg/hm2, after the application of the rare earth fertilizer, the sugarcane yield increases by 10. 5% and the cane sugar yield raises 16. 4% by contrast to same amount organic compound fertilizer of nitrogen, phosphorus and potassium without containing rare earth.
