| 摘 要： | 通过对信阳市完成的13个油菜"3414"试验、10个氮肥用量试验、10个五区丰缺试验数据进行汇总分析,建立了信阳市油菜施肥模型,摸清了在本区域内油菜单位产量养分吸收量、土壤有效养分校正系数、土壤供肥量、土壤养分丰缺指标等技术参数,制定出了信阳市油菜施肥建议,为指导全市测土配方施肥技术推广提供了依据。

| Abstract: | Rapeseed fertilization model of Xinyang City was established based on the summary and analysis of experimental data of 13 rapeseed“3414” experiments, 10 trials on the fertilization amount of nitrogen fertilizer and 10 nutrient deficiency and abundance ex-periments.Nutrient uptake amount per unit yield of rapeseed, soil available nutrients correction factor, soil nutrient deficiency and a-bundance index and other technical parameters in this region were figured out and proposals on rapeseed fertilization were made, which provides evidence for guiding technology promotion of soil testing for formulated fertilization in Xinyang City. |
