摘要
为探索玉米秸秆直接还田的方法,研究了不同促腐条件下玉米秸秆直接还田的腐解效果和对烤烟生长及产质量的影响。结果表明:促腐条件下玉米秸秆在烤烟移栽前腐解率在75%以上,较好地解决了土壤氮素养分与烤烟需肥规律吻合的矛盾;玉米秸秆直接还田可以改善烤烟农艺性状,提高烟叶产量和产值,提高烟叶开片度,降低烟叶含梗率,提高烟叶结构疏松度,增加烟叶糖含量和钾含量,提高烟叶评吸质量。以添加发酵菌曲的玉米秸秆直接还田处理效果较好。
Effects of maize stalk decomposition in field on growth,yield and quality of flue-cured tobacco were studied under different decay conditions.Results were as follows:the decay rate of maize stalk before tobacco transplanting was above 75%under accretion decay conditions.Maize stalk in field well addressed the relationship between soil nitrogen nutrition and fertilizers needed by tobacco plant.It also improves agronomic traits of tobacco plant,and hence output and value of flue-cured tobacco,enhance leaf length and width proportion,reduce stem ratio,enhance porosity of leaf tobacco,sugar and potassium content of leaf tobacco,and smoking quality of leaf tobacco.Maize stalk added with zymophyte yeast decay had the best effect
