摘要：

为了明确棉花综合品质与主要生态地质地球化学因子的关系，采用多目标地球化学调查法，研究河北省棉花纤维品质指标、棉花综合品质指数与各个主要土壤生态地球化学因素的关系。结果表明，冲洪积或冲积平原中的冲积平地较其他地貌条件更适宜棉花种植；潮土、潮褐土类型土中轻壤质、砂壤质、中壤质较其他土壤类型而言，更适宜棉花生长和优质棉花纤维的形成。河北省平原棉花种植区土壤硝态氮基本上分布在很低和低水平，其所占比例为69.06%；速效磷主要分布在低水平，分布在中、高水平上的样点仅占18.24%、3.07%；有效钾主要分布在中等水平、高和很高水平，分别占31.97%、44.67%。土壤钙含量较丰富，有效钙分布在8086~9658 mg/kg范围中；氧化态镁属于中等偏低水平；有效硫大多分布在很低和低水平，分布在中等水平的仅占15.45%。河北省平原区土壤铁主要分布在中、高水平，其比例分别为51.82%、42.73%；大部分地区土壤锌水平较低，分布在中等、高水平的仅为占15.45%、1.82%；锰含量水平中等适当；土壤硼主要属中等适量水平，所占比例为59.09%；土壤铜大多属于偏高水平，其比例占98.18%。在诸营养元素中，磷、钾素对棉花纤维品质的影响大于氮素，中微量元素中硼、锰、硫元素对棉花纤维品质的形成影响相对高于其他各元素。

Abstract:

In order to search the relation between cotton quality and main ecological geochemistry factor, with multiple target geochemical survey method, the correlation was studied between the cotton quality, integrated cotton fiber quality and the soil ecological geochemistry factor in plain area of Hebei Province. It was suitable for cotton growing in the alluvial flat of alluvial or diluvium plain compared with other landforms condition. There were suitable soil including light loam soil, sandy loam, loam soil of both fluvo-aquic soil and cinnamon soil, which conserved water and fertilizer well. And these kinds of soil were more suitable for cotton growth and increasing quality of cotton fiber. The soil nitrate nitrogen was in low or very low level, which the ratio was 69.06%. Most of available phosphorus was in low level, the medium and the high level only accounted for 18.24%, 3.07%. The medium and the high level of available potassium accounted for 31.97%, 44.67% respectively. The soil calcium content was abundant and distributed 8086-9658 mg/kg. The oxidation magnesium belonged to medium level or low level. Available sulfur content distributed mostly in very low or low level, and the ratio of medium level only was 15.45%. Available iron content was abundant, the medium and high level accounted for 51.82%, 42.73%. Available zinc was lack in most of area, and the ratio of medium and high only were 15.45%, 1.82%. Manganese, boron content was in right level. But available copper belonged to high level, which ratio reached 98.18%. In addition, the affection of phosphorus and potassium on cotton fiber quality were higher than nitrogen. B, Mn and S of elements content affected cotton fiber quality more highly than the other trace elements.
