摘要
以南疆地区沙土土壤为研究对象,采用一维近红外光谱与二维相关光谱分析技术相结合的方法,研究南疆地区土壤养分,对南疆地区土壤的分析研究有指导意义。试验土壤样品选取0～20cm,20～40cm,40～60cm深度的土壤,通过采用各二维相关光谱方法分析比较不同深度土壤的二维相关谱图得出结论：在20～40cm深度土壤内养分含量最高,0～20cm深度土壤养分含量其次,40～60cm深度土壤养分含量最少。这与化学方法所测得的土壤养分含量基本一致,说明采用二维相关方法分析土壤养分,便于检测土壤养分含量,为农业生产中的施肥调控提供一种新的方法。
Taken sandy soil in southern Xinjiang as the research object.Adopting the one-dimension near infrared spectroscopy combined with two-dimensional spectrum analysis technology to study the distribution of soil nutrients.It has guided significance in southern Xinjiang soil analysis and research.The tested soil samples were selected at 0~20cm,20~40cm,40~60cm depth of soil.By adopting the two-dimensional correlation spectroscopy methods to analyze the soil of different depth is two-dimensional correlation spectra concluded：In 20~40cm depth of soil nutrient content in the highest,0~20cm depth soil nutrient content secondly,soil nutrient content at least 40~60cm depth.The measured soil nutrient content and chemical methods are basically identical.Adopting the method of two-dimensional correlation analysis of soil nutrient,soil nutrient content,facilitate testing the fertilizer in agricultural production control provides a new method.
