中文摘要	为明确生物质炭输入对盐胁迫下玉米生物学性状的影响,以轻、中、重度盐渍化土壤为基础模拟不同程度的盐胁迫环境,设置0(CK),1%、2%、4%、8%生物质炭输入水平,进行室内玉米盆栽试验。检测播前及苗后盆栽土壤的理化指标,观测玉米种子萌发及其苗后的生物学性状。结果显示: 1%、2%、4% 生物质炭输入轻、中度盐渍化土壤可显著降低土壤总盐,但对pH 影响不显著; 8%生物质炭输入水平导致轻、中、重度盐渍化土壤pH 和总盐含量显著升高,pH 较CK 增加2. 93%、5. 49%、8. 16%,总盐含量较CK 增加31. 76%、9. 17%、11. 13%。生物质炭输入可以显著提高盐胁迫下玉米种子的活力,提高幅度与生物质炭输入量呈正相关。轻、中、重度盐胁迫下: 8%生物质炭输入处理中玉米种子发芽率提高145. 43%、174. 57%、73. 72%。2%、2%、4% 生物质炭输入处理中玉米茎粗和株高较CK 处理分别增加32. 73%、15. 19%、44. 76%和61. 78%、36. 50%、63. 96%; 8%、2%、8%生物质炭输入水平对玉米干物质累积量的促进效应最强,地上干物质累积量较CK 分别增加115. 9%、151. 2%、648%,地下干物质累积量较CK 分别增加117. 5%、91. 7%、241%; 生物质炭输入与玉米叶片MDA 含量降低,CAT、SOD 酶活性增强相关。轻、中、重度盐胁迫下酶活性表现: MDA 含量均在8%生物质炭输入水平降至最低; SOD 酶活性均在2%水平达最高; CAT 活性分别在2%、1%、8%输入水平达到最高。因此生物质炭可作为盐渍化土壤改良剂。
英文摘要	In order to Study the effect of biomass carbon input on biological characteristics of maize cultivated in saline soil,different salinized soils were used to simulate different salt stress environments. The study materials were gray desert soil in three salinity levels: level 1,low salinity,level 2,medium salinity,and level 3 high salinity with different percentage of biomass carbon inputs. Corn was cultivated in these media and the physicochemical indexes were investigated before and after sowing to observe the germination of maize seeds and their biological characteristics after emergence. The results showed that the 1%,2% and 4% biomass carbon inputs into level 1 and level 2 salinity soil could reduce the pH and total salt content of the soil. 8% biomass carbon input to salinity soil could induce the soil’s pH and total salt content up to the highest. Biomass carbon inputs to salinity soil could boost the corn seeds germination and promote the seedsvigor,the increasing range was positively related to biomass carbon input ratio. When the level 1,level 2 and level 3 salinity soil had 2%,2% and 4% biomass carbon inputs accordingly,the cultivated cornsstem diameter and plant height had the biggest increase,the 8%,2% and 8% biomass carbon inputs into the salinity soil accordingly could induce the biggest above and underground cornsdry matter accumulation,increasing ratio which compared with CK were 115. 9%,151. 2%,648% and 117. 5%, 91. 7%. 241%. The biomass carbon inputs were related to the cornsMDA content decrease and the increasing of CAT and SOD in the same time. The biomass carbon could be used as a kind of salinity soil improvement agent.
