To explore the effects of organic fertilizer nitrogen replacing chemical fertilizer nitrogen on the growth, carbon and nitrogen metabolism of hulless barley in the Qinghai Tibet Plateau, pot experiments were conducted under the same nitrogen, phosphorus, and potassium application rates. The differences in growth characteristics, leaf carbon and nitrogen balance, and nitrogen metabolism enzyme activity of hulless barley variety Kunlun 14 were compared and analyzed among different proportions of organic fertilizer nitrogen replacing chemical fertilizer nitrogen (0%, 40%, and 100%, designated as ORF0, ORF40, and ORF100) treatments. The results showed that compared with ORF0, the root length and old leaf carbon to nitrogen ratio of hulless barley significantly increased under ORF40 treatment, while the changes in plant height, aboveground or root biomass were not significant. Under ORF100 treatment, plant height and aboveground biomass significantly decreased, but root length and biomass significantly increased (P<0.05), and carbon to nitrogen ratio of new leaves significantly increased. Compared with ORF0 treatment , the activities of glutamate synthase (GOGAT) and glutamate dehydrogenase (GDH) in old leaves under ORF40 treatment were increased by 1.18%-2.53% and 17.39%-39.40%, respectively, from seedling stage to flowering stage. The GOGAT activity of new and old leaves under ORF100 treatment showed no significant difference, while the GDH activity significantly decreased. The activity of glutamine synthetase (GS) in the new leaves under ORF40 treatment was higher than that under ORF0 treatment during the heading and flowering stages. The activity of glutamine aminotransferase (GOT) in the new leaves was significantly increased by 22.22%-35.29% from seedling stage to flowering stage (P<0.05). The GS activity of both new and old leaves under ORF100 treatment significantly decreased. Overall, compared with the ORF0 treatment, the ORF40 treatment showed less variation in root length and plant height of hulless barley. The leaves showed more stable C/N, and the activities of GS and GDH increased in the old leaves, while the activities of GS and GOT increased in the new leaves. Both the new and old leaves under ORF40 treatment maintained a certain level of nitrogen metabolism ability, with the nitrogen metabolism ability of the old leaves being more stable, indicating that an appropriate proportion of organic fertilizer replacing chemical fertilizers is helpful for the stable growth and carbon and nitrogen metabolism of hulless barley plants.

为探讨青藏高原有机肥氮替代化肥氮对青稞生长及碳氮代谢的影响,在氮磷钾施用量相同条件下,通过盆栽试验,比较分析了不同比例有机肥氮替代化肥氮(0%、40%和100%,分别记为ORF0、ORF40、ORF100)处理下青稞品种昆仑14号生长特性、叶片碳氮平衡和氮代谢酶活性的差异。结果表明,与ORF0处理相比,ORF40处理下青稞的根系长度、老叶碳氮比均显著增加(P<0.05),株高及地上部和根系生物量变化不显著;ORF100处理下株高和地上部生物量均显著降低,根系长度和生物量均显著增加,新叶的碳氮比显著提高。与ORF0处理相比,ORF40处理的老叶中谷氨酸合成酶(GOGAT)和谷氨酸脱氢酶(GDH)活性在苗期至扬花期分别增加1.18%~2.53%和17.39%~39.40%(P<0.05);ORF100处理的新叶和老叶GOGAT活性无明显变化规律,GDH活性显著降低。ORF40处理的新叶谷氨酰胺合成酶(GS)活性在抽穗期和扬花期均高于ORF0处理,新叶中谷草转氨酶(GOT)活性在苗期至扬花期显著增加,增幅22.22%~35.29%;ORF100处理的新叶和老叶GS活性均显著下降。综合来看,与ORF0处理相比,ORF40处理下青稞根长和株高变化较小,叶片拥有更稳定的碳氮比,且老叶中谷氨酸合成酶和谷氨酸脱氢酶活性增加,新叶中GS活性和GOT增加,ORF40处理的新叶与老叶都保持了一定的氮代谢能力,其中老叶的氮代谢能力更为稳定,说明适宜比例的有机肥替代化肥有助于青稞植株稳健生长和碳氮代谢。

为探讨青藏高原有机肥氮替代化肥氮对青稞生长及碳氮代谢的影响,在氮磷钾施用量相同条件下,通过盆栽试验,比较分析了不同比例有机肥氮替代化肥氮(0%、40%和100%,分别记为ORF0、ORF40、ORF100)处理下青稞品种昆仑14号生长特性、叶片碳氮平衡和氮代谢酶活性的差异。结果表明,与ORF0处理相比,ORF40处理下青稞的根系长度、老叶碳氮比均显著增加(P<0.05),株高及地上部和根系生物量变化不显著;ORF100处理下株高和地上部生物量均显著降低,根系长度和生物量均显著增加,新叶的碳氮比显著提高。与ORF0处理相比,ORF40处理的老叶中谷氨酸合成酶(GOGAT)和谷氨酸脱氢酶(GDH)活性在苗期至扬花期分别增加1.18%~2.53%和17.39%~39.40%(P<0.05);ORF100处理的新叶和老叶GOGAT活性无明显变化规律,GDH活性显著降低。ORF40处理的新叶谷氨酰胺合成酶(GS)活性在抽穗期和扬花期均高于ORF0处理,新叶中谷草转氨酶(GOT)活性在苗期至扬花期显著增加,增幅22.22%~35.29%;ORF100处理的新叶和老叶GS活性均显著下降。综合来看,与ORF0处理相比,ORF40处理下青稞根长和株高变化较小,叶片拥有更稳定的碳氮比,且老叶中谷氨酸合成酶和谷氨酸脱氢酶活性增加,新叶中GS活性和GOT增加,ORF40处理的新叶与老叶都保持了一定的氮代谢能力,其中老叶的氮代谢能力更为稳定,说明适宜比例的有机肥替代化肥有助于青稞植株稳健生长和碳氮代谢。

To explore the effects of organic fertilizer nitrogen replacing chemical fertilizer nitrogen on the growth, carbon and nitrogen metabolism of hulless barley in the Qinghai Tibet Plateau, pot experiments were conducted under the same nitrogen, phosphorus, and potassium application rates. The differences in growth characteristics, leaf carbon and nitrogen balance, and nitrogen metabolism enzyme activity of hulless barley variety Kunlun 14 were compared and analyzed among different proportions of organic fertilizer nitrogen replacing chemical fertilizer nitrogen (0%, 40%, and 100%, designated as ORF0, ORF40, and ORF100) treatments. The results showed that compared with ORF0, the root length and old leaf carbon to nitrogen ratio of hulless barley significantly increased under ORF40 treatment, while the changes in plant height, aboveground or root biomass were not significant. Under ORF100 treatment, plant height and aboveground biomass significantly decreased, but root length and biomass significantly increased (P<0.05), and carbon to nitrogen ratio of new leaves significantly increased. Compared with ORF0 treatment , the activities of glutamate synthase (GOGAT) and glutamate dehydrogenase (GDH) in old leaves under ORF40 treatment were increased by 1.18%-2.53% and 17.39%-39.40%, respectively, from seedling stage to flowering stage. The GOGAT activity of new and old leaves under ORF100 treatment showed no significant difference, while the GDH activity significantly decreased. The activity of glutamine synthetase (GS) in the new leaves under ORF40 treatment was higher than that under ORF0 treatment during the heading and flowering stages. The activity of glutamine aminotransferase (GOT) in the new leaves was significantly increased by 22.22%-35.29% from seedling stage to flowering stage (P<0.05). The GS activity of both new and old leaves under ORF100 treatment significantly decreased. Overall, compared with the ORF0 treatment, the ORF40 treatment showed less variation in root length and plant height of hulless barley. The leaves showed more stable C/N, and the activities of GS and GDH increased in the old leaves, while the activities of GS and GOT increased in the new leaves. Both the new and old leaves under ORF40 treatment maintained a certain level of nitrogen metabolism ability, with the nitrogen metabolism ability of the old leaves being more stable, indicating that an appropriate proportion of organic fertilizer replacing chemical fertilizers is helpful for the stable growth and carbon and nitrogen metabolism of hulless barley plants.
