| 中文摘要: |
| 通过2005—2010 年连续6 年166 个大豆试验数据的分析，结果表明，土壤类型和气候条件均对
吉林省大豆产量和施钾效果产生显著影响。大豆在冲积土地区增产显著，其产量和钾肥的施用效果显著高于
白浆土和暗棕壤地区。吉林省降雨量年际间变化显著，明显影响大豆产量。干旱或涝害均会造成大豆的明显减
产，且降低钾肥的施用效果，涝害尤为严重。不同生态区因其光照、温度等气象因子对大豆产量有明显影响，
吉林省中部种植区产量明显高于东部种植区，但东部地区施钾增产效果显著。因此，吉林省大豆应根据土壤和
气候条件微调施钾量，从而提高大豆产量和钾肥利用率。 |
| 英文摘要: |
| The field experiment data of 166 soybeans were analyzed for 6 years in 2005-2010，the results showed
that soil type and climate conditions had obvious effects on soybean yield and potassium fertilizer efficiency in Jilin
province. On Alluvial soil，soybean yield and potassium fertilizer efficiency were significantly higher than those on Albic
soil and on dark brown forest soil. The change of annual rainfall in Jilin province significantly affected the soybean yield.
Drought and flood decreased soybean yield and potassium fertilizer efficiency seriously，especially in flooding years.
Different ecological zones due to the sunshine，temperature and other meteorological factors had obvious effects on
soybean yield，that in middle planting zone was higher than that in east planting zone，however，the effect of potassium
fertilizer in east plant zone was significant and yield increasing was remarkable. Therefore，we should adjust slight
potassium fertilizer rate according to the soil type and climate to increase soybean yield and use efficiency of potassium. |
