摘要/Abstract

摘要：

为探究烤烟油菜轮作及平衡施肥对土壤有机碳(SOC)含量的影响，通过田间小区试验，采用双因素裂区设计，测定烤烟与3个油菜品种（‘重蓉油1号’、‘德油早1号’和‘GSX-1’）轮作以及平衡施肥（减氮和增磷）下油菜季与烤烟季土壤的总有机碳(TOC)和可溶性有机碳(DOC)含量。结果表明，从油菜移栽初期到收获，SOC含量均有不同程度的上升，上升幅度为7.7%~166.49%；轮作处理的TOC含量和DOC含量相较对照有所增加，且收获期（180天）的TOC含量和DOC含量以‘重蓉油1号’最高，分别为对照处理的1.26和4.78倍。在烤烟整个生育期内，除个别处理外，其他土壤DOC含量呈下降趋势，TOC含量有所增加。此外，就施肥模式而言，减氮处理效果最佳。在烤烟收获期，除‘德油早1号’外，土壤TOC含量均以减氮处理最高，分别为常规施肥处理的1.20、1.44和1.02倍。综上，‘重蓉油1号’油菜与烤烟轮作、减施氮肥时SOC含量较高，是当地较优的种植模式。

Abstract:

To explore the effects of tobacco-rape rotation and balanced fertilization on soil organic carbon (SOC) content, a two-factor split plot design, which included tobacco rotation with three rape varieties (‘Chongrongyou 1’, ‘Deyouzao 1’ and ‘GSX-1’) and balanced fertilization (nitrogen reduction and phosphorus increase), was adopted to analyze the content of soil total organic carbon (TOC) and dissolved organic carbon (DOC) in rape season and tobacco season. The results showed that from the initial stage of rape transplanting to harvest, the SOC content increased to varying degrees, ranging from 7.7% to 166.49%. The content of TOC and DOC of the rotation increased compared with those of the control, and the content of TOC and DOC of ‘Chongrongyou 1’during the harvest period (180 d) were the highest, which were 1.26 and 4.78 times that of the control, respectively. In the whole growth period of tobacco, except some individual treatments, the DOC content in soil showed a downward trend, while the TOC content increased. In addition, in terms of fertilization mode, nitrogen reduction treatment had the best effect. In the harvest period of tobacco, except ‘Deyouzao 1’, the TOC content of soil in nitrogen reduction treatments was the highest, which was 1.20, 1.44 and 1.02 times that of the control, respectively. In conclusion, the SOC content is relatively high under ‘Chongrongyou 1’ -tobacco rotation and nitrogen reduction, which is a good local planting system.
