| 中文摘要: |
| 以当地主栽品种“新大坪”为试验材料，研究了揭膜对全膜覆盖马铃薯产量形成、品质及农田水分运转的影响。结果表明，马铃薯播种后75 d揭膜显著提高了马铃薯产量、产量构成要素和品质。与全生育期不揭膜（T5）相比，60天揭膜（T1）、75天揭膜（T2）、90天揭膜（T3）和105天揭膜（T4）分别增产4%、28%、26%和10%，其中T2处理产量最高。揭膜改善了马铃薯薯块品质，与T5相比较，T1、T2、T3和T4显著提高了薯块可溶性糖、可溶性蛋白、游离氨基酸、Vc和淀粉含量，降低了有机酸含量。综合效果以T2处理最好，有利于马铃薯薯块产量的提高和品质的改善。 |

| Local main cultivar of “Xindaping” was used to investigate the effect of removing film on tuber yield, quality and water movement of potato under whole film mulched cultivation. The results indicated that the tuber yield, yield components and quality of potato were improved for film removing on 75 days after planting. Compared with covering film during the whole growth period (T5), tuber yield in treatments of film removing on 60 days after planting (T1), film removing on 75 days after planting (T2), 90 days after planting (T3), and 105 days after planting (T4) were increased by 4%, 28%, 26%, and 10%, respectively. The tuber yield in treatment T2 was the highest. The quality of tuber was improved by removing film. Compared with T5, T1, and T2 treatments, T3 and T4 significantly increased the soluble sugar, soluble protein, amino acid, Vc and starch content, while decreased the content of organic acid. Generally, T2 was the better treatment in increasing both the yield and quality of film mulched potato. |
