摘　　要：为优化家庭长效花卉肥料配方,进一步研究简约水肥一体化,以"青苹果"竹芋盆栽试验得出的养分配方为依据,共设7个处理采用室内分析的方法研究了该专用长效肥料的养分规律。结果表明:加水冲洗药片状肥料基本上能够实现可控的EC、pH和硝态氮、磷和钾的均匀和长时间释放,且冲洗时长比片数对冲洗液中电导率、pH、硝态氮、磷、钾的量更有明显影响。同时,养分释放时间与氮、磷、钾累积释放率呈线性关系,用于竹芋的长效片状肥料需在原有基础上添加一定量的固体磷酸,减少硝态氮、磷、钾原料的用量。In order to optimize the family long-acting fertilizer formula,and study the contracted cucumber futher,taking the nutrient prescription from Calathea orbifolia （Linden） H. A. Kenn. pot experiment as the basis, through seven treatments, the nutrient rule of release discipline of long-acting fertilizer was studied by laborato- ry analysis. The results showed that washing medicine could realize controlled uniform amounts and long-time consistent for the EC,pH value and nitrate nitrogen,phosphorus and potassium and long time release,and the effect of washing timeon the EC, pH value, nitrate nitrogen, phosphorus and potassium were more obvious than the fertilizer number of tablets. The results also showed that there were liner relations between the release time and nitrogen,phosphorus and potassium. The long-acting tablet fertilizer used for arrowroot should add a certain amount of solid phosphoric acid,and reduce certain amount of NO3-N, P,K materials based on the original prescription.
