摘要： 本研究以牛轭草(Murdannia loriformis (Hassk.) Rolla Rao et KammathyS)为试验材料,通过不同量的氮磷钾施肥的处理,探讨和分析了牛轭草成坪有关形态及生理指标的变化。结果表明：(1)牛轭草的盖度随施肥处理时间的延长而逐渐增加,不同量的施肥处理的牛轭草盖度均高于CK对照处理,且存在显著差异；(2)除氮4水平施肥处理与CK处理分蘖数少且无显著差异外,其他施肥处理均比CK处理分蘖数多,并存在显著差异；(3)各施肥处理下的叶绿素含量均高于CK处理,除了处理3(N1P3N3)、4(N1P4N4)、8(N2P4N3)之外,其他施肥处理的叶绿素含量均与CK处理存在显著差异；(4)各施肥处理的地上部鲜重均比CK处理高,且除处理2、4、5、6、9、12、16之外,其余均与CK存在显著差异；(5)不同施肥量下牛轭草植株株高和叶宽均高于CK处理,但不存在显著差异。

Abstract: The authors discuss and analyze the changes of morphological and physiological indicators for the turf ofMurdannia loriformis under different fertilization amounts of nitrogen, phosphorus and potassium. The results showed that: (1) the coverage was gradually increased with the extension of fertilization processing time, and the coverage of different treatments was also higher than that of CK treatment with a significant difference; (2) except nitrogen level 4, fertilization treatment had more tillers number than CK treatment with a significant difference; (3) the chlorophyll content of each fertilization treatments was higher than that of CK treatment basically and apart from the treatment of 3 (N1P3N3), 4(N1P4N4) and 8 (N2P4N3), the chlorophyll contents of the other fertilization treatments were significantly different from that of CK treatment; (4) the aboveground fresh weight of all fertilization treatments were higher than that of CK, and there was a significant difference between CK and the treatments except 2, 4, 5, 6, 9, 12, 16; (5) the plant height and leaf width of different fertilization treatments were higher than that of CK treatment, but there was no significant difference.
