摘要
使用青海省统计局发布的2000—2023年青海省统计年鉴,提取2000—2023年青海省物资消耗和化肥施用量数据,对青海省24年间化肥施用情况进行纵向比较,剖析青海省不同化肥用量的变化趋势。结果表明:青海省24年间化肥总施肥量(折纯)年增加量共增长-2.62万t,年增长率为-10.92%;氮(N)肥年增加量共计增长-1.51万t,年增长率为-6.57%;磷(P_(2)O_(5))肥年增加量共计增长-0.95万t,年增长率为-3.96%;钾(K_(2)O)肥年增加量共计增长-0.17万t,年增长率为-0.71%;复合肥(折纯)年增加量共计增长0.02万t,年增长率为0.08%。说明青海省24年间化肥总施肥量(折纯)年增长率、氮(N)肥年增长率、磷(P_(2)O_(5))肥年增长率和钾(K_(2)O)肥年增长率均为负增长,复合肥(折纯)年增长率为正增长。可为青海省科学施肥的决策提供数据支撑。
Using the 2000-2023 Qinghai Provincial Statistical Yearbook issued by the Qinghai Provincial Bureau of Statistics,data on material consumption and fertilizer application in Qinghai Province from 2000 to 2023 were extracted to make a longitudinal comparison of fertilizer application over the 24 year period and to analyze the trend of different fertilizer usage in Qinghai Province.The results showed that the annual increase of total fertilizer application(pure)in Qinghai Province during the 24-year period was-26,200 tons,with an annual increase rate of-10.92%.The total annual increase of nitrogen(N)fertilizer was-15,100 tons,with an annual growth rate of-6.57%.Phosphorus(P_(2)O_(5))fertilizer annual increase in total growth of-9500 tons,an annual growth rate of-3.96%.Potassium(K_(2)O)fertilizer annual increase in total growth of-1700 tons,an annual growth rate of-0.71%.Compound fertilizer(pure)total annual increase of 200 tons,an annual growth rate of 0.08%.It shows that the annual growth rates of total fertilizer application(pure),nitrogen(N)fertilizer,phosphorus(P_(2)O_(5))fertilizer and potassium(K_(2)O)fertilizer during 24 years in Qinghai Province are all negative,while the annual growth rate of compound fertilizer(pure)is positive.It can provide data support for the decision-making of scientific fertilization in Qinghai Province.
