| 摘 要： | 通过大田试验,以马铃薯为供试作物,研究了垄沟覆膜集雨对水分和氮肥利用率的影响,结果表明:在施肥条件下,垄沟覆膜集雨处理的马铃薯产量分别比土垄集雨和裸地平作提高126.8%和277.2%,水分利用效率提高127.4%和252.1%,氮肥利用率提高8.82和16.47个百分点;在不施肥条件下,垄沟覆膜集雨处理的马铃薯产量分别比土垄集雨和裸地平作提高153.2%和195.9%,水分利用效率提高168.5%和184.3%。 |

| Abstract: | The effects of plastic-covered ridge rainwater harvesting on potato yield and nitrogen use efficiency were studied in a field experiment. The results showed that, compared with ridge and furrow rain harvesting without plastic-covered ridge and bare flat soil, the plastic-covered ridge rainwater harvesting system could increased potato yields by 126.8% and 277.2%, and water use efficiency by 127.4% and 252.1% in condition of N application. Without fertilization, the plastic-covered ridge rainwater harvesting system could also increase potato yields by 153.2% and 195.9%, and water use efficiency by 168.5% and 184.3%. The plastic-covered ridge rainwater harvesting system increased nitrogen fertilizer use efficiency by 8.82 and 16.47 percentage point. |
