万载县中潴灰鳝泥田肥效试验研究

Study on Fertilizer Efficiency in Grey Eel-mud Field of Wanzai County

在江西万载县中潴灰鳝泥田进行了"3414"肥效试验。结果表明:氮是限制水稻产量的主要因子,其次是磷,最后是钾。氮、磷、钾肥的最佳施用量分别为12.02、8.47、3.92 kg/667 m2。

The ＂3414＂ fertilizer efficiency test in the grey eel-mud field of Wanzai county in Jiangxi province was carried out,the results showed that the main factor of limiting rice yield was nitrogen,followed by phosphorus and potassium.The optimum application rates of nitrogen,phosphorus and potassium fertilizer were 12.02,8.47 and 3.92 kg/667 m2 respectively.
