摘要
对艾纳香氮肥施用量试验结果表明,施氮可提高艾纳香原料产量和药用有效成分含量。尿素用量25kg／667m2 可达生物和原料产量的峰值,6～10kg／667m2可达有效成分含量的峰值,20kg／667m2可达有效成分产量的峰值;氮素用量过多,产量和有效成分含量均下降,经济系数和氮的有效性降低。有效成分中L-龙脑与其他成分(艾纳香油)的比例也可施氮调控。
The results show that N application will increase the yield of raw material and content of medical active ingredient. 25 kg/667m^2 of urea application can reach the peak of biological and raw material yield, 6- 10 kg/667m^2 of urea application can reach the peak of medical active ingredient content, 20 kg/667m^2 of urea application can reach the peak of active ingredient yield. Too much N causes the decrease of yield, active ingredient content, economical coefficient and N availability. N application can also regulate the ratio of L-camphol and the oil in the active ingredient.
