绿肥作为一种生态环保的肥料,在绿色农业的发展中起到积极的作用。这一作用,在一些特殊的农作物的种植中显得尤为突出。近年来在西南地区,尤其是在云南地区,绿肥光叶苕子的种植,对当地烟草的产量、质量都起到了很大的改善作用。光叶苕子可提高烟叶质量烟草是一种特殊的经济作物,其种植和加工是云南省的支柱产业之一,该省常年种植面积超过25万公顷。与我国大部分烟区类似,烟田由于多年连作,加上长期使用化肥而忽视有机肥的投入,造成土壤板结,地力衰退,影响有效养分的释放和迁
Green manure, as an eco-friendly fertilizer, plays a positive role in the development of green agriculture. This effect is particularly prominent in the cultivation of some special crops. In recent years in the southwestern region, especially in Yunnan, the planting of green leaf light-leaf prickly ash has played a significant role in improving the output and quality of local tobacco.
