| 摘 要： | 通过大田试验方法,研究分析生物质炭不同施入量(0、10、20、30 t·hm-2)对旱作农田白浆土土壤碳、氮变化的影响。结果表明,生物质炭施入土壤可有效提高土壤有机质(SOM)、全氮(TN)、微生物生物量碳(MB-C)、微生物生物量氮(MB-N)、硝态氮(NO3--N)、铵态氮(NH4+-N)含量,且这些指标均随施入量的增加而提高。与对照(CK)处理相比,土壤SOM与TN含量分别提高了6.88%~43.77%、1.68%~15.91%,土壤MB-C与MB-N分别提高了9.76%~60.88%、6.72%~68.91%,且均在30 t·hm-2的施用量下达到最大值。添加生物质炭可以显著提高各深度土层NH4+-N和NO3--N含量,总体表现为0—10 cm>10—20 cm>20—30 cm。建议以30 t·hm-2生物质炭为白浆土旱作农田土壤的最佳施用量。

| Abstract: | In the present study, the effect of different biochar application rate (0,10,20,30 t·hm-2) on soil carbon and nitrogen content was explored via field test. It was shown that application of biochar increased contents of soil organic matter (SOM), total nitrogen (TN), microbial biomass carbon (MB-C), microbial biomass N (MB-N), nitrate (NO3--N) and ammonium (NH4+-N), and the more application, the higher the contents. Compared with CK, SOM, TN, MB-C, MB-N content was increased by 6.88%-43.77%, 1.68%-15.91%, 9.76%-60.88%, 6.72%-68.91%, respectively. The highest contents for above indexes were all reached at the highest biochar application rate. Application of biochar significantly increased NH4+-N and NO3--N content in every soil depth, and showed an overall tendency of 0-10 cm>10-20 cm>20-30 cm. Thus, application of 30 t·hm-2 was recommended for albic soil. |
