摘要：探究不同形态氮素对半夏(Pinellia ternata)生长和品质的影响,可为半夏的优质高产栽培提供氮肥施用依据。本研究采用单因素随机区组试验,设置铵态氮、硝态氮、酰胺态氮3种形态氮素及5、10、15 g·m^(?2)施氮量处理,以不施氮素为对照,测定半夏植株的农艺性状、产量及品质指标。结果表明,硝态氮5 g·m^(?2)处理下半夏珠芽和母茎的直径和重量最大;铵态氮10 g·m^(?2)处理下半夏产量最高;铵态氮15 g·m^(?2)处理下次黄嘌呤和腺苷含量均最高;酰胺态氮10 g·m^(?2)处理下尿苷含量最高;硝态氮15 g·m^(?2)处理下鸟苷和水溶性蛋白含量最高。通过熵权-TOPSIS对农艺性状、产量和品质进行综合评价,得出铵态氮15 g·m^(?2)处理最佳,酰胺态氮10 g·m^(?2)处理最差。研究结果表明,施用15 g·m^(?2)的铵态氮总体上有利于半夏的生长和品质提高。
To explore the effects of different forms of nitrogen on the growth and quality of Pinellia ternata,and to provide the basis for nitrogen fertilizer application for high quality and high yield cultivation of P.ternata.A single-factor randomized block design was used.Three forms of nitrogen of ammonium nitrogen,nitrate nitrogen,and amide nitrogen were applied at rates of 5,10,and 15 g·m^(?2).The agronomic traits,yield and quality indexes of P.ternata plants were determined with no nitrogen application as control.The results showed that the nitrate nitrogen treatment 5 g·m^(?2)produced the largest bulbil and mother stem diameters and maximum fresh weights.Maximum tuber yield was achieved with ammonium nitrogen at 10 g·m^(?2).Phytochemical analysis demonstrated that ammonium nitrogen at 15 g·m^(?2)enhanced hypoxanthine and adenosine concentrations,while amide nitrogen application 10 g·m^(?2)optimized uridine content.Notably,nitrate nitrogen at 15 g·m^(?2)simultaneously maximized guanosine levels and water-soluble protein content.A multi-criteria evaluation integrating agronomic traits,yield,and quality indices through an entropy-weighted TOPSIS(technique for order preference by similarity to and ideal solution)model revealed significant treatment efficacy differences.The ammonium nitrogen treatment at 15 g·m^(?2)demonstrated optimal performance,while the 10 g·m^(?2)amide nitrogen application exhibited the lowest efficacy.The results showed that application of 15 g·m^(?2)ammonium nitrogen was generally conducive to the growth and quality improvement of P.ternata.
