| 摘 要： | 以小麦为供试作物,研究了长期施用化肥条件下,不同耕法处理对白浆土锰、锌含量及形态影响。结果表明,长期免耕在减缓微量元素锰、锌含量下降上优于普翻与深松处理;土壤有效态锰、锌含量3种处理均表现为减少;形态变化上免耕处理有机结合态锰锌下降幅度低于深松和普翻,由于长期施用化肥,土壤酸度的改变,碳酸盐结合态和铁锰氧化物态各个处理均表现为下降。

| Abstract: | The effect of content and forms of Mn and Zn in long-term different cultivation in albic soil of wheat field were studied. The results showed that zero-tillage was excelled to conservation tillage and deep tillage on slowing total content of Mn and Zn. The available Mn and Zn decreased in three cultivation. During long-term experiment, zero-tillage had lesser in decreasing OM-Mn, Zn than conservation tillage and deep tillage, but had bigger effect in decreasing CARB-, OX-Mn, Zn than the other two sides. This was because the soil acid and organic matter should all be decreased by using fertilizer. |
