摘要
研究了贵阳市植烟大黄泥土、大泥土、大砂泥土、黄砂泥土、黄黏泥土、砾石黄砂泥土等6个土种土壤养分含量与烟叶质量的关系,旨在为该区优质烤烟生产提供理论依据。结果表明,贵阳市6个植烟土种土壤除有效硼缺乏,有效硫、有效铁、有效锰含量过高外,其他土壤养分含量总体处于适宜水平;与大黄泥土、大泥土、黄砂泥土、黄黏泥土土种烟叶糖碱比显著相关的土壤养分指标分别为硝态氮含量,全氮含量,铵态氮含量,全磷、有效钾含量;大黄泥土、大泥土、黄砂泥土、黄黏泥土生产出的烟叶糖碱比均与某一个土壤养分指标(分别为硝态氮、全氮、铵态氮、全磷含量)呈典型的直线回归函数关系,而大砂泥土、砾石黄砂泥土2个土种生产的烟叶糖碱比与土壤养分含量没有明显的直线相关关系。大泥土上种植的烟叶最接近于优质烟叶标准,黄黏泥土最差,应在大泥土上大面积推广烤烟生产。
The relationship between nutrients content of six different soil types （ big yellow soil,big soil, big sandy soil,yellow sandy soil,yellow clay,gravel yellow sandy soil） in Guiyang city and the quality of tobacco leaf was studied.The results showed that the nutrients content of six soil types in Guiyang city was basically within the optimum range,except that available B content was lack,available S,Fe,Mn contents were too high.Nitrate N content, total N content,ammonia N content,total P and available K content were significant related with the quality of tobacco planted in big yellow soil,big soil,yellow sandy soil,yellow clay,respectively.Sugar alkali ratio of tobacco planted in big yellow soil,big soil,yellow sandy soil,yellow clay had a typical linear regression equation relation with a soil nutrient（ nitrate N,total N,ammonia N,to-tal P） content,but that in big sandy soil and gravel yellow sandy soil had not obvious linear relation with the soil nutrient content.As to the quality of flue-cured tobacco,the big soil was the best,and yellow clay＆amp;nbsp;was the worst.The soil type of big soil should be largely popularized for flue-cured tobacco production.
