紫花苜蓿是一种优质高产且各类家畜均喜食的豆科牧草,在中国种植历史悠久且种植面积较大,但是,这些仅限于中国北方地区,在中国南方却少有种植。究其原因,与南方大部分地区土壤呈酸性有关,酸性土壤带来了铝的毒害,这些都大大影响了紫花苜蓿在南方的栽培与推广。结合现今国内外对植物耐酸铝性的研究以及云南本地野生资源的状况,阐述苜蓿耐酸铝性研究的进展与意义。
Alfalfa is a high quality and high yielding legume forage that is well received by all kinds of domestic animals. It has a long history of cultivation and large area planted in China. However, these are limited to the northern part of China and rarely to the south of China. The reason for this is that the soils in most parts of the South are acidic, and the acid soils are responsible for the poisoning of aluminum. All these have greatly affected the cultivation and popularization of alfalfa in the south. Combined with the current domestic and foreign research on plant acid-proof aluminum and Yunnan local wild resources, the progress and significance of the research on acid-proof aluminum of alfalfa is described.
