摘要
选择3种植烟土壤(酸性、中性及偏碱性),设置禾本科秸秆与化肥配施,单施化肥等处理,通过对植烟土壤根区氧化还原电位(Eh)的原位测定,研究施用有机物对植烟土壤根区Eh、烤烟吸收矿质营养效率和烟叶质量等的影响。结果表明:配施秸秆能提高土壤根区的Eh,显著增加烤烟的营养效率吸收以及增加烟叶的产量和产值。
Three typical soils,acldlc soil,neutral soil and light alkaline soil are chosen for this experiment. Research was carried out with different fertilizations：wheat straws with chemical fertilizers,corn straws with chemical fertilizers and chemical fertilizers. Through the measurements of redox status（Eh） of root region in tobacco soil ,effects of organic material on Eh of root region in tobacco soil ,efficiency of tobacco mineral nutrient and quality of tobacco leaves were investigated. The results showed that Eh of root region ,efficiency of tobacco nutrient ,yield and output value were significantly increased by use of gramineous straws with chemical fertilizer.
