摘要
通过对广东某高尔夫球场果岭土壤粒径、酸碱度、速效N、P、K、Ca、Mg、pH和有机质等含量的测定分析,结合国内外相关指标,对高尔夫球场土壤理化性状进行评价并提出一些施肥建议。结果表明:球场砂性太重、有机质含量太低,是制约果岭土壤保水保肥性的因素;不平衡施肥是导致果岭质量下降的主要原因。建议球场加大有机肥的投入,提高氮肥和钾肥的施用频率,减少每次施用量,定期喷施0 4%～2%KNO3或KH2PO4;减少磷肥的投入,重在通过施用有机肥等提高其有效性。球场还应进行测土施肥和平衡施肥以求可持续发展。
The soils were sampled from the green of golf course in Guangdong.Soil pH and organic matter, available N,P,K,Ca, Mg were determined. The results showed:the highly sandy texture and lower content of organic matter were limited factors of soil conservative water and fertilizer. It is the unbalanced fertilization that decreased the quality of the golf course. Some suggestions were put forwarded: The first was to emphasize the input of organic fertilizer; The second was to apply nitrogen and potassium in more frequent way while decrease the amount of each time, as well as to spay 0.4%～2% KNO_3 or KH_2PO_4 in some time interval;The third was to decrease the use of phosphorus and to enhance the effectiveness of it via the higher amount of organic fertilizer, etc. The manager of the golf course may pay more attention in the features of the soil by soil test and have the fertilization balanced so as to have a sustainable development.
