摘　　要：凉山是四川粳稻种植集中区,常年种植面积约50余万亩,主要分布于海拔1,500-2,200m之间。海拨1,700-1,900m的山林地带粳稻区具有实施有机栽培良好的自然及社会环境条件。发展凉山有机粳稻栽培,扩大凉山有机粳稻出口,对当地农民增收,维护农田生态平衡,提高凉山知名度具有重要的意义。而开展有机栽培优质粳稻新品种的引进,筛选及配套栽培技术的研究、推广又是凉山发展粳稻有机栽培的关键措施。Liangshan Prefecture is a major growing area of round-grained rice, with a growing area of 500,000 mu annually, distributing over an altitude of 1,500-2,200 meters. Hilly terrain with an altitude of 1,700-1,900 m provides a nice natural and social environment for round-grained rice's organic cultivation. Developing organic round-grained rice's cultivation and expanding export of round-grained rice in Liangshan has a significant role in increasing the local farmers' income and maintaining local farm lands' ecological balance. On the other hand, introduction of new varieties, their selection and research on corresponding cultivation methods are the key issues in developing round-grained rice cultivation.
