摘要:

为探讨腐熟剂与生物炭协同作用对水稻秸秆还田后土壤质量和水稻生长的影响,设计5个处理——对照(S1)、单独秸秆还田(S2)、秸秆还田配施腐熟剂(S3)、秸秆还田配施生物炭(S4)、秸秆还田配施腐熟剂和生物炭(S5),通过田间试验,分析不同处理对土壤理化性质、酶学性质、微生物群落结构和水稻生产的影响。结果表明,与S2处理相比,腐熟剂与生物炭共同配施处理下,土壤的全氮、全磷、全钾、有机质、有效磷和速效钾含量显著(P<0.05)增加,水稻成熟期土壤过氧化氢酶和蔗糖酶的活性分别显著提高16.06%和19.11%,土壤中微生物的多样性和丰度亦得到提升,水稻产量和地上部干重分别增加了11.42%和11.74%,水稻的地上部氮、磷、钾素吸收总量分别显著提高24.00%、26.12%和13.21%。该研究凸显了腐熟剂与生物炭的协同作用在促进秸秆高效还田、改善土壤生态系统方面的潜力,为强化秸秆等农业废弃物高效还田利用新技术的实际应用提供了科学依据。

Abstract:

In order to investigate the synergistic effects of decomposition agents and biochar on soil quality and rice growth with straw returning to the field, five treatment groups were designed: control group (S1); straw return group (S2); straw return with decomposition agent (S3); straw return with biochar (S4); straw return with both decomposition agent and biochar (S5). A field experiment was performed to analyze the impacts of different treatments on soil physicochemical properties, enzymatic activities, microbial community structure, and rice growth and development. It was shown that the combined application of decomposition agent and biochar significantly (P<0.05) increased the contents of total nitrogen, total phosphorus, total potassium, organic matter, available phosphorus, available potassium in soil as compared with the S2 treatment. The soil catalase activity and sucrase activity were significantly increased by 16.06% and 19.11%, respectively, at the rice maturity stage under the S5 treatment than those under the S2 treatment. Besides, the combined application of decomposition agent and biochar positively enhanced the soil microbial diversity, abundance. Additionally, compared with the S2 treatment, the rice yield and aboveground biomass were significantly increased by 11.42% and 11.74%, respectively, under the S5 treatment, while the total uptake of nitrogen, phosphorus and potassium in the aboveground part of rice was significantly increased by 24.00%, 26.12% and 13.21%, respectively. These findings demonstrated promising practical benefits of decomposition agent and biochar in enhancing nutrient uptake and increasing rice yield, highlighted the synergistic effects in promoting efficient straw incorporation and improving the soil ecosystem, provided scientific basis for the practical application of new technologies for the efficient utilization of agricultural waste such as straw.
