%X <span style=\"font-size:14px;\">利川红皮山药产量高、品质好、抗性强，是山药中的佼佼者。因多年重茬、品种混杂等原因退化严重，面积及单产呈下滑趋势，对利川特色产业发展十分不利。本文简述了利川山药产业的发展史，描述了山药退化的主要表现，分析了品种退化的成因，针对性制定了提纯复壮的技术措施，并为全面抓好山药提纯复壮工作提出了新的建议。仅供当地政府、技术部门及广大种植者借鉴参考。</span><br />
<span style=\"font-size:14px;\">Lichuan Hongpi yam has high yield, good quality, and strong resistance, making it the best among yams. Due to years of continuous cropping and mixed varieties, the degradation is serious, with a downward trend in area and yield per unit area, which is very detrimental to the development of Lichuan’s characteristic industries. This article briefly describes the development history of the yam industry in Lichuan, describes the main manifestations of yam degradation, analyzes the causes of variety degradation, formulates targeted technical measures for purification and rejuvenation, and puts forward new suggestions for comprehensively grasping the purification and rejuvenation work of yam. It is only for reference by local governments, technical departments, and growers.</span>
