有机堆肥对黄壤烟田培肥效应研究

Study on the Effect of Organic Compost on Fertility Improvement of Tobacco Yellow Soil

采用田间试验研究了有机堆肥对烤烟产质量及对黄壤烟田培肥效应的影响.结果表明,供试堆肥在不同程度上促进了烤烟的烟叶质量和产值,其中以堆肥每公顷施4 500kg效果最好,保证了烟田养分的持续供应,可避免新整理烟田烟株后期脱肥,同时提高新整理烟田土壤肥力.

A field experiment was conducted in Chongqing to study the effect of different rates of organic compost on the growth and quality of tobacco and on fertilization of newly consolidated tobacco soil.Laboratory analysis showed that organic compost application in different rate treatments all promoted the growth,nutrient uptake,quality and output of tobacco in different degrees.The treatment of organic compost at 4 500kg/ha gave the best result,which ensured a continuous supply of nutrients in the tobacco field,avoided nutrient deficit of the tobacco plants at the later growth stages and improved the physical and biological properties and fertility of the newly consolidated tobacco fields.
