利用野生苜蓿资源进行耐酸铝研究的前景

The Prospect in Studying Aluminum Tolerance of Alfalfa on the Base of wild Accessions

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 an excellent legume forage, which has good quality and high productivity and is loved by all kinds of livestock. Alfalfa has been cultivated for many years and for larger areas in our country. However, alfalfa can only grow well in north of China. Because of the acid soil and the aluminum toxicity in south of China, alfalfa is seldom cultivated there. This article based on the researches of the aluminum tolerance about many plants in the whole world and the conditions of the native resource-Deqin alfalfa in Yun- nan province, viewed the progress and importance of researching the aluminum tolerance about alfalfa.
