| 摘 要： | 以安丘生姜为试材，研究了生姜不同生长期的养分吸收特性，以及不同钾水平对生姜产量和土壤肥力的影响。结果表明：姜对钾素的需求最多，每生产1 000 kg姜需要从土壤中吸收6.1 kg N、2.36 kg P2O5、9.4 kg K2O。K3处理〔K2O 70 kg?（667 m2）-1〕的生姜产量最高，但与K2处理〔K2O 50 kg?（667 m2）-1〕之间差异不显著。通过产量和施肥量的拟合曲线获得最高产量的钾肥施用量为60 kg?（667 m2）-1，综合考虑不同钾水平对生姜养分吸收和土壤肥力的影响，得出本试验条件下生姜周年生产的钾肥（K2O）投入量为667 m2 50～60 kg比较适宜，同时适宜的氮钾比例为4∶5～4∶6。

| Abstract: | Field experiment was conducted to study ginger(Zingiber officinale Rosc.)nutrient characteristics,yield and soil fertility by different K fertilizer levels.The results showed that ginger nutrient absorption amount was firstly for K.Ginger must absorb N 6.1 kg,P2O5 2.36 kg and K2O 9.4 kg from soil,if its root-stem yield was 1 000 kg.The yield for K3 treatment was the highest,but there was no significant difference in yields between K2 treatment and K3 treatment.We could obtain by linear equation of yield and... |
