| 摘 要： | 为明确全膜垄作栽培方式对黄土高原旱作马铃薯生长及产量的影响,以克新1号马铃薯品种为材料,设全膜双垄垄上播种（A1）、全膜单垄垄上播种（A2）、全膜单垄垄上微沟播种（A3）和露地常耕平作（CK）4种栽培方式的田间试验。结果表明,全膜垄作栽培方式均能够提高各生育时期0~40cm土层土壤含水量,以全膜单垄垄上微沟播种效果最好;与露地常耕平作相比,全膜垄作栽培方式可以极显著或显著提高马铃薯株高、冠幅、茎粗及叶片SPAD值。同时,全膜垄作栽培方式能够提高马铃薯产量、商品薯率,降低马铃薯青薯率和烂薯率,全膜单垄垄上微沟播种比全膜双垄垄上播种的产量增加5.53%, 比全膜单垄垄上播种的产量增加14.23%,其中全膜单垄垄上微沟播种极显著高于其他处理,可作为西北黄土高原旱作区节水高产栽培模式。

| Abstract: | In order to clarify the effect of whole plastic-film mulching ridging cultivation on the growth and yield of rainfed potato of Loess plateau, “Kexin 1” was selected as the material in this experiment with four kinds of cultivation systems of the whole film double ridge sowing (A1), the whole film single ridge sowing (A2), the whole film single ridge micro-furrow (A3) and traditional planting (CK). The results showed that the whole film ridge cultivation systems could improve soil moisture content in depth of 0-40 cm, and the whole film single ridge micro-furrow sowing displayed the best effect; Compared with traditional planting, the whole film ridge could significantly improve the potato plant height, stem diameter and leaf SPAD value. At the same time, it was found that the whole film ridge cultivation could increase potato yield, commercial tuber percentage, reduce the rate of green potatoes and rotten potatoes. The whole film single ridge micro-furrow sowing could increase yield by 5.53% of the whole film double ridge sowing, 14.23% of the whole film single ridge sowing, respectively. The yield of whole film single ridge micro-furrow sowing was significantly higher than that of other treatments, which could be used as water saving cultivation system in northwest Loess Plateau. |
