中文摘要:
      [目的]确定木醋液在辽西北地区低、中肥力土壤中的合适浓度,揭示木醋液对土壤酶活性的影响。[方法]设置0.10%,0.15%,0.30%不同浓度木醋液的低、中肥力土壤盆栽试验,测定盆栽小白菜的产量指标,同时测定土壤酶活性,评估其土壤肥力质量。[结果]木醋液显著提高了小白菜茎粗和根长,进而提高了小白菜产量,其中低肥力土壤施用0.30%的木醋液效果最好,中肥力土壤施用0.15%的木醋液效果最好,与对照相比分别将低、中肥力土壤小白菜鲜重提高了57.78%和46.06%。木醋液显著提高了土壤淀粉酶、脲酶、蛋白酶、磷酸酶、过氧化氢酶、脱氢酶活性;低肥力土壤的土壤肥力生物指数、酶活性指数在0.30%的木醋液处理下最高,中肥力土壤在0.15%的木醋液处理下最高。[结论]木醋液可以作为辽西北地区低、中肥力土壤一种良好的土壤改良剂,用于提高土壤肥力,增加蔬菜产量。
英文摘要:
      [Objective] To reveal the effect of wood vinegar concentration on soil enzymatic activities in order to determine the optimal application concentration of wood vinegar in low and medium fertility soils in Northwest Liaoning Province.[Methods] Pot experiments were conducted, and wood vinegar with different concentrations (0.10%, 0.15% and 0.30%) were selected. The agronomic indexes of pot grown pakchoi were determined and the soil enzyme activities were measured to evaluate the soil fertility quality.[Results] Wood vinegar significantly improved the stem diameter and the root length of pakchoi, and consequently increased the yield of pakchoi. Wood vinegar with 0.30% concentration showed the best effect in low fertility soil while wood vinegar with 0.15% concentration showed the best effect in medium fertility soil, and the fresh weight of pakchoi was increased by 57.78% and 46.06%, respectively, compared with the control. Wood vinegar also significantly enhanced the activities of soil amylase, urease, protease, phosphatase, catalase and dehydrogenase. Biological index of fertility and enzymatic activity number were the highest, in low fertility soil with 0.30% concentration of wood vinegar and in medium fertility soil with 0.15% concentration of wood vinegar.[Conclusion] Wood vinegar can be used as a good soil amendment to improve soil fertility and increase vegetable yield in Northwest Liaoning Province.
