| 选取定薯4号为试材，进行田间试验，设6个处理，分别为：黑膜双垄全覆膜垄播（A）、白膜双垄全覆膜垄播（B）、黑膜单垄覆膜垄播（C）、白膜单垄覆膜垄播（D）、垄播覆草（E），裸地种植为对照（CK），研究旱地不同覆盖垄作种植对马铃薯生长、产量、品质和经济效益的影响。结果表明：不同覆盖处理较对照成熟期提早5～21 d，全生育期缩短，出苗率提高5.7～11.6个百分点，株高增加1.2～10.5 cm，植株开展度扩大11.1%～42.1%；不同覆盖处理较对照单株结薯数增加0.61～2.82个，单株结薯重增加3.2%～15.6%，小区大薯重增加0.02%～29.1%，小区小薯重增加4.5%～56.6％，产量增加11.5%～31.2%，除处理B和E较CK商品薯率提高1.82～3.06个百分点，其它覆盖处理较CK降低0.16～7.02个百分点；处理B较CK干物质含量增加4.2%，其它覆盖处理较CK减少1.37%～17.49%；处理B、D和E粗淀粉含量与CK差异不显著，处理A、C较CK减少6.98%～13.37%；不同覆盖处理较CK粗蛋白含量降低3.83%～9.36%，维生素C含量降低1.61%～15.43%；不同覆盖处理薯块Zn和Ga含量均高于CK，分别增加10.22%～21.17%和17.93%～84.14%，Fe含量降低22.12%～28.32%，Se含量除处理C和D较CK减少2.63%～7.02%，其它覆盖处理较CK增加5.26%～12.28%；处理C、A和E较CK每公顷纯收入分别增加5.97%、16.31%和20.95%，其它覆盖处理较CK减少22.85%～54.27%。 |

| The purpose of this study is to investigate potato growth, yield, quality and economic benefit for different cover and ridge tillage planting in the dry land. Dingshu#4 was selected as material, six treatments were carried out in the field experiment, including whole film coating planting with black film double ridges (A), whole film coating planting with white membrane double ridges (B), the single ridge with black film coated planting (C), the single ridge with white film coated planting (D), grass planting for control (E), and bare land (CK). The results showed that emergence rate was increased by 5.7%～11.6%, plant height by 1.2～10.5 cm, plant spreading by 11.1%～42.1% in different mulching treatment. The number of tuber per plant was increased by 0.61～2.82, the tuber weight per plant by 3.2%～15.6%, big potato ratio by 0.02%～0.02%, small potato weight by 4.5%～4.5%, yield by 11.5%～31.2%, commodity potato rate by 1.82%～3.06%. There was no significant difference for crude starch content in B, D and E compared with control. The crude protein content in different coverage was decreased by 3.83%～9.36% than control. |
