2014年在凤凰县通过大田试验研究不同绿肥品种翻压还土对烤烟产质量及土壤性状的影响。结果表明,光叶紫花苕综合生物学性状较好,对缺磷土壤有改良作用;黑麦草可改良缺磷地区土壤;箭舌豌豆翻压还土的烟叶产量、产值较高,质量较好;满园花是改良酸化土壤较好的绿肥品种,尤其在缺磷地区是较好的绿肥品种;不同绿肥品种翻压还土均能提高烟叶的产量。
In 2014, field trials were conducted in Fenghuang County to study the effects of different green manure types on the quality and soil properties of flue-cured tobacco. The results showed that the comprehensive biological characters of M. purpureum had better comprehensive biological characters and improved the phosphorus deficiency soils. Ryegrass improved the soil of phosphorus deficiency areas. Manyuanhua is a better green manure to improve the acidified soils, especially good green manure in phosphorus deficient regions. Different green manure varieties can both increase the yield of tobacco leaves.
