摘要
通过肥料试验 ,对红壤退化人工草地的合理施肥技术进行了研究。结果表明 :缺磷是导致草地退化的主要养分限制因素 :磷、钾肥配施具有显著的增产作用 ;改良初期氮肥的施用将提高磷肥肥效。
Effective fertilization was studied by fertilizer experiment in red soil deteriorate pasture. The results showed that phosphorus was the critical factor for deteriorate pasture in red soil region in Yunnan-Guizhou plateau. Marked pasture yield was obtained by PK-fertilizer. During the initial stage of the improving pasture, P-fertilizer effect was raised by N-fertilizer applied.
