摘要:

以蚕豆连作障碍严重的土壤为试验材料,设计4种生物质炭不同施用方式,探讨生物质炭不同施用方式对根际土壤酚酸物质降解、微生物区系、酶活性及蚕豆产量和品质的影响。结果表明,采用不同方式施用生物质炭,均能降低蚕豆根际土壤酚酸物质含量,提高土壤酶活性,改变微生物区系。但4种施用方式下生物质炭发挥作用效果不同,综合土壤环境和蚕豆产量及品质指标分析,条施深施效果优于条施浅施,种植穴深施效果优于种植穴撒施,条施深施效果优于种植穴深施。

Abstract:

In this study, four different application methods of biochar were designed, the soil with severe continuous cropping obstacle of broad bean was used as the test material, the effects of different application methods of biochar on the degradation of phenolic acids, microflora, enzyme activity, yield and quality of broad bean in rhizosphere soil were investigated. The results showed that the different application methods of biochar could reduce the content of phenolic acids in rhizosphere soil, improve soil enzyme activity and change the microflora in rhizosphere soil of broad bean. Under the four application methods, the effect of biochar was different. Based on the comprehensive analysis of soil environment and yield and quality indicators of broad bean, the deep application of row replacement was better than the shallow application of row replacement, the deep application of the planting hole was better than the spreading application of the planting hole, and the deep application of row replacement was better than the deep application of the planting hole.

Key words: biochar, application methods, broad bean, continuous cropping obstacle, quality
