摘要

通过盆栽模拟铅（Pb）胁迫试验，研究了不同秸秆生物炭添加量（20，40 g/kg土壤）、不同鸡粪添加量（20，40 g/kg土壤）、秸秆生物炭和鸡粪等量复配（各20 g/kg土壤）处理对Pb胁迫下玉米生长和生理特性的影响。结果表明：施用生物炭和鸡粪不同处理均显著增加铅胁迫下玉米的株高、鲜重、光合色素含量、光合性能和抗氧化酶活性。生物炭和鸡粪等量复配处理较对照提高鲜重69.9%、株高50.0%、叶绿素b含量50.0%、净光合速率（Pn）97.9%、蒸腾速率（Tr）126.5%、气孔导度（Gs）132.6%、超氧化物歧化酶活性（Superoxide dismutase，SOD）68.4%、过氧化物酶活性（Peroxidase，POD）69.4%、过氧化氢酶活性（Catalase，CAT）115.3%、脯氨酸含量88.6%、可溶性糖含量48.6%。生物炭和鸡粪等量复配处理对促进铅胁迫下玉米的生长，提高叶片的光合能力和抗氧化能力效果最佳，为改善重金属铅污染的土壤质量和作物生长提供了经济有效的途径。

Abstract

A pot experiment was conducted to investigate the effects of different stalk-derived biochar added (20

40 g/kg soil)

different chicken manure added (20

40 g/kg soil)

combination of stalk-derived biochar and chicken manure (20 g/kg soil

respectively) applications on the growth and physiological characters of maize under lead stress. Results showed that all treatments with stalk-derived biochar or/and chicken manure addition significantly increased plant height and fresh weight of maize

photosynthetic pigment contents

photosynthesis characteristics and antioxidant enzyme activities. Amending soil with stalk-derived biochar and chicken manure together produced the largest increment in maize growth and physiological characteristics. This effect was additive

with 69.9%

50.0% greater fresh weight and plant height

50.0%

97.9%

126.5%

132.6% higher chlorophyll b content

net photosynthetic rate (Pn)

transpiration rate (Tr) and stomatal conductance (Gs)

68.4%

69.4%

115.3% higher activities of superoxide dismutase (SOD)

peroxidase (POD)

catalase (CAT)

88.6%

48.6% higher proline and soluble sugar

respectively. The combination of stalk-derived biochar and chicken manure treatment played the best effective role on promoting the growth of maize

improving leaf photosynthetic and antioxidant capacity under lead stress. This study provides a cost-effective way for improving the soil quality of Pb-contamination and crop growth.
