| 摘 要： | 为了改良植烟土壤质量,探讨连续施用不同种类生物炭对植烟土壤养分含量的影响,通过3年大田定位试验研究了连续施用不同生物炭(CK：不添加生物质炭；T1：添加烟秆炭；T2：废弃烟叶炭；T3：玉米秸秆炭)下植烟土壤中的养分含量。结果表明：①连续施用不同种类生物质炭能够显著提高土壤有机质、全氮、速效磷和速效钾含量,但对全磷、全钾以及碱解氮的作用并不显著。②在2018年采收期,三种生物质炭处理分别提高有机质10.26%、9.12%和6.96%；提高全氮10.36%、18.29%和9.03%；提高速效磷6.96%、18.57%和9.82%；提高速效钾16.53%、33.84%和13.05%。③随着试验年限的延长,添加烟秆炭对土壤有机质含量提升效果最好,其次是废弃烟叶炭,玉米秸秆炭最次。废弃烟叶炭对提升土壤全氮、速效磷和速效钾含量效果最佳。综合分析来看,连续施用生物质炭能提高土壤养分含量,改良土壤肥力,以废弃烟叶炭效果最好,适宜大面积推广。

| Abstract: | In order to improve the quality of tobacco-planting soil, the effects of continuous application of different kinds of biochar on the tobacco-planting soil nutrient content was discussed. Through 3-year locating experiment, the continuous application of different biochar (CK: no biochar added; T1: tobacco stem-derived biochar; T2: wasted tobacco leaf-derived biochar; T3: maize straw-derived biochar) nutrient content of tobacco-planting soil. The results showed that the contents of soil organic matter, total nitrogen, available phosphorus and potassium could be significantly increased by continuous application of different biochar, but the contents of total phosphorus and potassium, alkali-hydrolyzed nitrogen had no significant influence. In the harvest period of 2018, three biochar treatments increased organic matter by 10.26%, 9.12% and 6.96%, respectively; increased total nitrogen by 10.36%, 18.29% and 9.03%, respectively; increased available phosphorus by 6.96%, 18.57% and 9.82%, respectively; and increased available potassium 16.53%, 33.84% and 13.05%, respectively. With the extension of the test period, the addition of tobacco stem-derived biochar had the best effect on the increase of soil organic matter content, followed by wasted tobacco leaf-derived biochar and maize straw-derived biochar. However, the wasted tobacco leaf-derived biochar had the best effect on increasing the content of soil total nitrogen, available phosphorus and available potassium. According to comprehensive analysis, continuous application of biochar can improve soil nutrient content and soil fertility, and the effect of wasted tobacco leaf-derived biochar worked best to application and prospect. |
