摘要: 探讨缓解根系腐解液自毒物质抑制番茄幼苗生育的方法.试验以珍珠岩基质进行盆栽试验,研究了珍珠岩基质中添加碳化玉米芯对番茄根系腐解液抑制番茄幼苗生长、光合作用及番茄叶片保护酶活性变化的缓解效果.结果表明:与对照相比,施用番茄根系腐解液对幼苗的生物量、叶绿素含量、光合作用指标均具有显著的抑制作用,番茄叶片的保护性酶活性在处理初期提高,随着处理时间的延长,POD和CAT活性明显下降,同时显著增加了番茄叶片内MDA的含量.在添加碳化玉米芯或活性炭可显著缓解番茄根系腐解液对番茄幼苗的毒害作用.与活性炭相似,碳化玉米芯具有显著缓解番茄根系腐解液自毒物质抑制番茄幼苗生长的作用.因此,番茄生产中施用碳化玉米芯可作为防止番茄连作障碍的措施之一.

关键词: 番茄, 自毒作用, 活性炭, 碳化玉米芯

Abstract: We examined the way which alleviates autotoxicity in tomato.Tomato seedlings were transplanted in perlite as growth substrate.Decomposed tomato root solution(DS) was added to Hoagland solution with or without the addition of activated charcoal or carbonized maize cob.Biomass,photosynthesis and antioxidant enzymes activity of tomato seedlings were systematically investigated.Results showed that DS suppressed the biomass,photosynthesis and chlorophyll contents of tomato seedlings.At the same time the activities of POD,CAT in leaf were increased firstly,then decreased and the MDA content was increased by the treatment of DS.DS-induced growth inhibition and physiological changes,however,were greatly alleviated by application of carbonized maize cob and activated carbon.Similar to activated carbon,carbonized corn cob could alleviate the DS induced inhibition on the growth of tomato seedlings.Carbonized corn cob can be used to prevent the plants from monocropping obstacles.

Key words: Tomato, Autotoxicity, Activated carbon, Carbonized maize cob
