摘要
[目的]通过水稻田间氮肥、磷肥和钾肥的对比试验,摸清常规施肥下氮肥、磷肥和钾肥的利用率现状和测土配方施肥提高氮肥、磷肥和钾肥利用率。[方法]设测土配方施肥、常规施肥、空白3个大区,测土配方施肥、常规施肥2个大区各设正常用肥和缺氮、缺磷、缺钾4个处理,共计9个处理,探讨常规施肥下氮肥、磷肥和钾肥的利用率现状和测土配方施肥提高氮肥、磷肥和钾肥利用率。[结果]测土配方施肥提高肥料利用率为:N为6.39%、P_2O_5为2.99%、K_2O为27.76%。[结论]测土配方施肥比常规施肥可以提高肥料利用率,值得推广。
[Objective] The aim was to explore the utilization status of nitrogen fertilizer, phosphate fertilizer and fertilizer application in the conventional fertilizer application and the application of soil test, and nitrogen fertilizer, phosphate fertilizer and fertilizer utilization rate, through the comparison test of nitrogen fertilizer, phosphate fertilizer and potash fertilizer in paddy field. [Method] The soil formula fertilization, regular fertilization and blank areas were set up ,and the two large areas of soil measuring and fertilization and conventional fertilizing were normally used for fertilizer and nitrogen deficiency, phosphorus deficiency and potassium deficiency. So total 9 processing were set for exploring the utilization status of nitrogen fertilizer, phosphate fertilizer and fertilizer application in the conventional fertilizer application and the application of soil test, and nitrogen fertilizer, phosphate fertilizer and fertilizer utilization rate, through the comparison test of nitrogen fertilizer, phosphate fertilizer and potash fertilizer in paddy field. [Result] The fertilizer utilization rates of the soil test was as following： N was 6.39%, P2O5 was 2.99%, K2O was 27.76%. [Conclusion] The application of soil tested formula could improve the utilization rate of fertilizer and it was worth promoting.
