| 摘 要： | 通过田间试验研究了连作障碍对干旱地区8个马铃薯品种的影响.结果表明:连作总体上抑制了8个品种马铃薯的株高、茎粗、商品率、单株产量和总产量,但抑制程度因马铃薯品种不同而异,其中‘青薯2号’的平均总产量和平均单株产量最高,分别为518.07kg和5.11kg;‘大西洋’的平均商品率最高为75.01%;‘费乌瑞它’的平均总产量最低为276.74kg;‘陇薯3号’的平均单产最低为3.56kg;‘青薯9号’商品率最低为62.69%.综合评价8个马铃薯品种,‘青薯2号’抗(耐)连作障碍能力相对最强,‘费乌瑞它’最弱. |

| Abstract: | A field experiment to study on the effects of eight potato cultivars to overcome continuous cropping obstacles in the arid regions.The results showed that continuous cropping generally suppressed the potato plant height,stem diameter,commodity rate,yield per plant and the total output.However,the degrees of the inhibition were influenced by different potato varieties.Among all of these degrees,average total yield and average yield per plant of Qingshu 2 were the highest,which were respectively 518.07 kg,5.11 kg.And the average commodity rate of the Atlantic was the highest for the 75.01%.The minimum of the average total production of Favorita was 276.74 kg.And the minimum of Longshu 3's average per unit area yield was 3.56 kg.Besides,the minimum of Qingshu 9's commodity rate was 62.69%.Of the eight varieties Qinshu 2 had the strongest resistance to continuous cropping obstacle.The resistance of Favorita was the weakest. |
