| 摘 要： | 以贵州春马铃薯威芋5号为研究对象,通过大田试验研究了不同生物有机肥对马铃薯产量、结薯性状、养分与品质和土壤肥力的影响,结果表明：与习惯施西洋复合肥750kg/hm 2+追施尿素112.5kg/hm 2相比,加施生物有机肥1 800kg/hm 2可使马铃薯出苗率增加,马铃薯产量提高2.11%~26.46%,单株结薯数提高5.45%~38.18%,单株产量提高1.41%~47.16%,均以加施RW促腐剂混合有机肥处理最佳;加施不同生物有机肥可以显著提高马铃薯磷素含量,增幅为19.55%~42.46%,同时可使马铃薯淀粉含量提高2.44~8.69个百分点,但对马铃薯块茎中的氮素、水分和还原糖含量无明显影响;从土壤养分变化来看,与习惯施肥相比,加施生物有机肥使土壤有机质、全氮、碱解氮、有效磷和速效钾含量分别提高49.31%~91.35%（金葵子LPK生物肥除外）、38.21%~52.36%、10.42%~21.74%、10.92%~68.41%和10.53%~39.47%。综合来看,RW促腐剂混合有机肥可作为贵州高海拔地区春马铃薯高产优质栽培的最佳生物有机肥。

| Abstract: | Weiyu No.5 (spring potato variety in Guizhou) was used in an field experiment to study the effects of different biological organic fertilizers on potato yield, characteristics such as nutrient and quality as well as soil fertility. The results showed that the application of biological organic fertilizer could significantly increase the emergence rate of potato, and the yield increased by 2.11%-26.46%; the number of potatoes per plant increased by 5.45%-38.18%; the yield per plant increased by 1.41%-47.16% compared with the conventional fertilization. T2 treatment in which the RW was added as an organic decomposition enhancer was the best. The content of phosphorus in potato tubers was increased by 19.55%-42.46% significantly, and the content of starch was increased by 2.44-8.69 percentage points, but no significant change in contents of nitrogen, water content and reducing sugar. The application of biological organic fertilizer significantly increased the contents of soil organic matter, total nitrogen, alkali-hydrolysis nitrogen, available phosphorus and available potassium by 49.31%-91.35% (except Jinkuizi LPK biological fertilizer), 38.21%-52.36%, 10.42%-21.74%, 10.92%-68.41% and 10.53%-39.47% compared with T1 treatment, respectively. In general, RW can be used as the best biological organic fertilizer for high yield and high quality cultivation of spring potato in the high altitude area of Guizhou. |
