福清市中稻测土配方施肥肥料利用率试验

Experiment of Soil Testing and Formula Fertilization for Medium Rice in Fuqing City

在福清市中稻上进行测土配方施肥和缺素处理试验,结果表明测土配方施肥处理的水稻籽粒和秸秆氮磷钾含量均高于缺素处理,提升了结实率、千粒重、晒干率、有效穗等产量构成因子,水稻产量最高,且极显著高于缺氮处理。福清市中稻氮肥肥料利用率为40.47%,磷肥利用率为19.51%,钾肥利用率为66.70%。

Effect of nitrogen deficiency,phosphorus deficiency,potassium deficiency on medium rice growth and development was studied with soil testing and formula fertilization as control,results showed that compared to control,the seed setting rate,1000-grain weight,dry rate,effective panicle number were decreased.nutrient deficiency treatment reduced content of nitrogen,phosphorus,potassium in aboveground vegetative organs.The control had the maximum yield and significantly higher than nitrogen deficiency treatment.The utilization efficiency of nitrogen,phosphorus and potassium in Fuqing were 40.47%,19.51%and 66.70%respectively.
