摘要

为探索改善土壤质量和提升水稻产量的农艺措施，通过田间小区试验，设置对照（CK）、深翻30 cm（T1）、生物炭15 t/hm

（T2）、生物炭15 t/hm

+深翻30 cm（T3）处理，探究土壤性质和水稻产量对不同农艺措施的响应。结果显示，与对照相比，施用生物炭使土壤渗透系数、有机质、水稻产量、穗粒数和生物量分别提升224.66%、22.42%、9.46%、23.90%和6.51%；深翻对土壤性质及水稻产量无显著影响；生物炭配合深翻使土壤渗透系数和水稻产量分别增加184.25%和9.93%；生物炭和深翻仅对穗粒数有显著交互效应；水稻产量和生物量均与土壤渗透系数和有机质呈现显著正相关；穗粒数与土壤渗透系数呈极显著正相关。结果表明，施用生物炭是改善土壤质量并提高水稻产量的有效措施，可以通过改善土壤通透性、提高有机质含量，增加水稻穗粒数最终提高产量。

Abstract

Treatments including the control （CK）， deep tillage of 30 cm （T1）， biochar 15 t/hm

（T2）， and biochar 15 t/hm

+ deep tillage of 30 cm （T3） were set up to conduct a field experiment to study the response of the properties of soil in paddy fields and the yield of rice to different agronomic measures in order to investigate agronomic measures for improving the quality of soil and increasing the yield of rice. The results showed that the application of biochar significantly increased the permeability coefficient in soil， organic matter， the yield of rice， the number of grains per panicle， and the biomass by 224.66%， 22.42%， 9.46%， 23.90%， and 6.51%， compared with that of the control. Deep tillage had no significant effect on the physicochemical properties of soil in paddy fields and the yield of rice. Biochar combined with deep tillage significantly increased the permeability coefficient in soil and the yield of rice by 184.25% and 9.93%， respec

tively. Biochar and deep tillage plowing had a significant interactive effect on the number of grains per panicle. The yield of rice and the biomass were significantly positively correlated with the permeability coefficient in soil and organic matter. There was a significant positive correlation between the number of grains per panicle and the permeability coefficient in soil. It is indicated that the application of biochar is an effective measure to improve the quality of soil and increase the yield of rice. It can improve the permeability in soil， increase the content of organic matter and the number of rice grains per panicle， and ultimately increase the yield of rice.
