含稀土长效全元复混肥是在一般氮、磷、钾复混肥的基础上，加入２％～４％的改性稀土微肥添加剂后制成。通过３年１０个点试验，探讨含稀土长效全元复混肥（１２－５－８）在水稻上的施用效果。试验结果表明：３年１０个试验平均，施用含稀土长效全元复混肥的处理，水稻平均产量６８６２．５ｋｇ／ｈｍ２，比不含稀土的等氮磷钾复混肥的处理增产４９６ｋｇ／ｈｍ２，增产率为７．８％。 Long-lasting all-element compound fertilizer with rare earth is based on the general nitrogen, phosphorus and potassium compound fertilizer, adding 2% to 4% of modified rare earth fertilizer additives made. Through 3 years and 10 points experiment, the application effect of long-lived all-solid fertilizer containing rare earth (12-5-8) on rice was discussed. The results showed that the average yield of rice was 6862.5kg / hm2, which was higher than that of NPK fertilizers without rare earths by 496kg / hm2, yield increase of 7.8%.
