宁夏六盘山区芹菜栽培对氮肥施用量的响应差异
Response difference of celery cultivation to nitrogen fertilizer application rate in Liupan Mountain area of Ningxia
为解决宁夏六盘山区芹菜生产过程中由于氮肥施用不当引起的一系列问题,以芹菜品种皇后为供试材料,通过单因素多水平随机区组试验设计,研究不同供氮水平(0、150、300、450、600 kg‧hm-2)对芹菜产量和品质等方面的影响。结果表明,适量的氮肥施用有助于芹菜对钾素和磷素的吸收,在增施氮肥后,能够提高芹菜的植株高度、植株周长、叶柄长、干物质积累和产量,且增产范围在15.65%~33.28%。通过对产量进行回归分析得出,芹菜取得最高产量时氮肥用量为394.75 kg·hm-2,最佳经济效益氮肥用量为287.07 kg·hm-2。此外,在一定范围内增施氮肥,会提高芹菜的硝酸盐、粗纤维、维生素C和可溶性固形物含量。采用TOPSIS法对芹菜的多项指标进行评价,N450处理的评分最高,N0处理最低。综上,为减少土壤环境污染,提高氮肥利用率,推荐宁夏六盘山区种植芹菜时氮肥施用量为287.07~394.75 kg·hm-2。
In order to solve a series of problems caused by improper application of nitrogen fertilizer in the production process of celery in Liupan Mountain area of Ningxia, the celery variety Queen was used as the test material, and the effects of different nitrogen supply levels (0, 150, 300, 450, 600 kg·hm-2) on the yield and quality of celery were studied by single factor and multi-level randomized block design. The results showed that the appropriate amount of nitrogen supply was beneficial for celery to absorb potassium and phosphorus. After the application of nitrogen fertilizer, the plant height, perimeter, petiole length, dry matter accumulation, and yield of celery were significantly increased, with an increase ranging from 15.64% to 33.27%. Through the regression analysis of yield, it was concluded that the highest nitrogen fertilizer application for celery was 394.75 kg·hm-2, and the optimal economic benefit nitrogen fertilizer application was 287.07 kg·hm-2. In addition, increasing nitrogen fertilizer within a certain range will increase the content of nitrate, crude fiber, vitamin C and soluble solids in celery. TOPSIS method was used to evaluate and analyze several indexes of celery. The results showed that N450 treatment had the highest score and N0 treatment had the lowest score. In summary, in order to reduce soil environmental pollution and improve the utilization rate of nitrogen fertilizer, it is recommended that the amount of nitrogen fertilizer should be 287.07-394.75 kg·hm-2 when planting celery in Liupan Mountain area of Ningxia.
