摘要
通过合理配施肥料,优化施肥配方,摸清水稻对氮、磷、钾肥的利用率,为合理制定三亚市施肥方案提供科学依据.结果表明:本试验条件下配方施肥处理均显著高于其他处理产量,较不施肥、缺氮、缺磷和缺钾处理,分别提高了131.73%、92.69%、10.11%和16.12%.另外配方施肥处理下N、P2O5和K2O养分利用率分别为41.45%、27.07%和52.29%.说明本试验中施肥配方对提高水稻产量有显著作用,并有效提高肥料利用率.
Abstract
By applying fertilizers in a balanced manner,optimizing the fertilizer formulation,and understanding the efficiency of rice in utilizing nitrogen,phosphorus and potassium fertilizer,this study aims to provide scientific basis for the rational formulation of fertilizer program in Sanya City.The results showed that the yield of formula fertilization treatment was significantly higher than that of other treatments,and 131.73%,92.69%,10.11%and 16.12%were increased compared with no fertilization,nitrogen,phosphorus and potassium deficiency treatments.In addition,the nutrient utilization rates of N,P2O5 and K2O were 41.45%,27.07%and 52.29%under formula fertilization treatment.The results indicated that the fertilization formula had a significant effect on increasing rice yield and improving fertilizer utilization rate effectively.
