摘要
为改良土壤,提高烟叶质量,实现会东烟叶生产可持续发展,2008—2012年连续5年采用烤烟-绿肥轮作还田田间试验与室内分析相结合的方法,研究了长期绿肥还田对烤烟产质量以及土壤改良的影响。结果表明,长期绿肥还田不仅提高烟叶均价、上等烟比例、经济效益,而且显著提高烤后烟叶含钾量,化学成分较协调;绿肥还田量15000～22500kg/hm2时,烟叶外观质量较好,评吸得分较高;同时绿肥还田增强土壤酶活性,提高土壤养分与土壤含水量,对于土壤改良、恢复土壤肥力有重要意义。
To improve soil improvement,tobacco quality and make sustainable development of flue-cured tobacco production in Huidong tobacco growing-area were the purpose of this research.With tobacco-green manure crop rotation field experiments and indoor analysis for five consecutive years from 2008 to 2012,the field experiment was conducted to study long-term green manure to field on the yield,quality of flue-cured tobacco and soil improvement.The results showed that green manure could improve average price,fine tobacco ratio and economic benefits.The potassium content was significantly increased and the chemical composition was more coordinate.The appearance quality was better,and smoking score was higher while the used amount was 15000-22500 kg/hm 2.Meanwhile,the soil enzyme activity,soil nutrient and water content were also enhanced.It played an important role in soil improvement and recovering the soil fertility.
