摘　　要：以低海拔地区的冕宁县回坪乡、冕宁县宏模乡、普格县鲁基乡和高海拔地区的布拖县拉达乡,布拖县火烈乡、布拖县乐安乡为试验点,研究了布拖当地品种黄洋芋、乌洋芋、西薯3号在不同生态种植区的生长、产量及品质。结果表明,西薯3号在不同的种植区单株产量、单株结薯数、大薯数均优于黄洋芋和乌洋芋,西薯3号在产量及质量方面表现较好,可在凉山地区推广种植。海拔对春马铃薯的影响趋势表现为高海拔地区的株高低于低海拔地区,主茎数大于低海拔地区,单株结薯数低于低海拔地区,大中薯率高于低海拔地区。除海拔外,地形、土壤肥力等也会影响马铃薯的生长、产量及质量性状,导致不同生态区不同品种在生长、产量及质量性状上表现出复杂性和多样性。Huiping Township and Hongmo Township of Mianning County,Luji Township of Xide County in the low-altitude area,Lada Township,Huolie Township and Le'an Township of Butuo County in high-altitude area were used as experimental sites to study the influences on growth,yield and quality of spring potato in different ecological planting areas of Liangshan prefecture.The results showed that the yield per plant,the number of potato per plant and the number of big potato in different planting areas were better than those of purple potato and yellow potato.The yield and quality of Xishu 3 were better in Liangshan that it may promote planting in the area.The trend of altitude on spring potato of the plant height in high-altitude was lower than that in low-altitude,the number of main stems was higher than that in low altitude,the number of potato per plant was lower than that in low altitude,and the rate of large and medium potato was higher than that in low altitude.In addition,geographical position,soil fertility,etc also affected the growth,yield and quality traits of potatoes,resulting in the complexity and diversity of growth,yield and quality traits of different potatoes in different ecological regions.
