不同形态氮素对半夏生长及品质的影响
Effects of nitrogen forms on the growth and quality of Pinellia ternata
摘要
Abstract
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.关键词
