摘要
通过对仙草不同施肥水平的田间试验,研究了武平县岩前镇仙草对氮、磷、钾的肥料效应,结果表明,合理施用氮、磷、钾肥对仙草的增产效应是钾肥>氮肥>磷肥。钾肥的增产量最大,每667m2增产179.3 kg,增产率32.7%;氮肥的增产次之,为163.2 kg,增产率28.9%;磷肥的增产最小,为147.8 kg,增产率25.5%。仙草每667m^2最佳施氮(N)、磷(P_2O_5)、钾(K_2O)量分别为12.59 kg、6.05 kg、15.68 kg,三要素比例为1∶0.48∶1.25;最佳经济产量每667m^2为723.92 kg。
The fertilizer effects of different nitrogen（N）, phosphorus（P） and potassium（K） levels based on ＂3414＂ experiment design on Xiancao（Mesona chinensis Benth.） were studied at Yanqian Town of Wuping county. The results showed that the effect of yield increase of N, P and K fertilizer on Xiancao ranked KNP, with a yield increase of 32.7%, 28.9% and 25.5% respectively. The every 667m^2 optimal application rates of N, P_2O_5 and K_2 O for Xiancao were 12.59 kg, 6.05 kg and 15.68 kg respectively, with a proportion of 1∶0.48∶1.25, which resulted in the maximum economic every 667m^2 yield of 723.92 kg.
