| 摘 要： | 通过2001年和2007年两次定点取样和分析,研究了三门峡市烟田土壤养分现状及动态变化.结果表明,三门峡市烟田土壤表现为中性偏碱性;有机质和氮素含量适宜优质烤烟生产;速效磷含量差异较大,平均含量中等;速效钾和有效锌平均含量较高,但需补充钾、锌营养的烟田比例较大;水溶性氯含量平均值较低,符合优质烤烟生产标准;土壤硼营养普遍缺乏,超过60%的烟田处于极缺水平.与2001年同期相比,2007年土壤pH值总体呈增加趋势,碱性特点更为突出;有机质和氯素营养有所增加,且含量分布较集中,适宜烤烟生长和营养调控的烟田比例增加幅度较大;速效磷含量平均值提高幅度较大,磷素含量不足的烟田比例变化不大,达极缺水平的烟田比例成倍增加;速效钾含量平均值略有降低,但仍属"丰富"水平;水溶性氯含量平均值明显减少,含量小于30mg·kg-1的烟田比例增加将近1倍;有效锌平均含量增加幅度较大,含量缺乏的烟田比例大幅度降低;有效硼普遍缺乏,硼营养严重不足的烟田大幅度增加.提出了"控氮、增磷、补钾,分类施锌和普遍补硼"及"不施碱性肥料"的施肥策略,强调施用农家肥或微生物有机肥、推广绿肥掩青和秸秆覆盖等栽培措施改良烟田土壤.

| Abstract: | The nutrients situation and its dynamic variation in tobacco field soil of Sanmenxia city was studied by positional sampling and analyzing in 2007 and 2001.The results showed that the tobacco field soil in Sanmenxia city was neutral and deflected alkaline;the contents of soil organic matter and nitrogen was optimum for flue-cured tobacco planting;the differ-ence of available P content in soil was great,the average content was middle;the average content of available K and Zn was high,but there still were a l... |
