摘要
研究了不同材质覆盖处理对烟田水土流失、土壤养分含量以及烤烟生长发育、产量、质量的影响。结果表明:各个覆盖处理均能减少烟田水土和养分流失,调节土壤水分含量,促进烟株生长发育,减轻病害的发生,提高烤烟的质量和产值。在5个处理中,以地膜盖垄(移栽后35 d揭膜)+稻草盖沟处理的经济效益最好,地膜盖垄处理的次之。
The effects of five different mulching treatments on the water and soil loss , soil nutrient content in tobacco field , as well as the growth , yield and quality of flue -cured tobacco were studied .The results indicated that all mulching treatments could reduce the loss of water , soil and nutrient in tobacco field , regulate soil moisture content , promote the growth and development of to-bacco plants , alleviate the occurrence of tobacco diseases , and enhance the quality and output value of flue -cured tobacco .Among 5 treatments, the treatment of covering ridge with plastic film （removing plastic film on the 35th day after transplanting） plus cover-ing ditch with rice straw obtained the best economic benefit , which was followed by the treatment of only covering ridge with plastic film.
