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8086～9658mg/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。 In order to clarify the relationship between the comprehensive quality of cotton and the main eco-geo-geochemical factors, a multi-objective geochemical survey method was used to study the relationship between cotton fiber quality index and cotton comprehensive quality index and various major eco-geochemical factors in Hebei Province. The results show that the alluvial flat in the alluvial or alluvial plain is more suitable for cotton planting than other landform conditions. The light loam, sandy loam and mid-loam in the alluvial and cinnamon soil are more than other soil types Suitable for cotton growth and high-quality cotton fiber formation. Soil nitrate nitrogen in plain cotton planting area in Hebei Province was mainly distributed at very low and low levels, accounting for 69.06% of the total; available phosphorus was mainly distributed at low levels, with only 18.24% of samples distributed at medium and high levels, , 3.07% respectively. Available potassium was mainly distributed at medium level, high level and high level, accounting for 31.97% and 44.67% respectively. Soil calcium content is rich, available calcium distribution in the range of 8086 ~ 9658mg / kg; magnesium oxide is a moderate low level; available sulfur are mostly distributed at very low and low levels, accounting for only 15.45% of the average level. Soil iron in the plain of Hebei Province was mainly distributed in the middle and high levels, with the proportions of 51.82% and 42.73%, respectively. The soil Zn levels in most areas were low and distributed at medium and high levels only accounting for 15.45% and 1.82% respectively. Manganese Moderately appropriate levels of content; soil boron is moderately moderate level, accounting for 59.09%; soil copper mostly belong to the high level, the proportion accounted for 98.18%. Among all the nutrients, the effects of phosphorus and potassium on the fiber quality of cotton were greater than that of nitrogen, while the contents of boron, manganese and sulfur in middle and trace elements were higher than those of other elements.
