摘要:
以玉米沈农T120种子为试验材料,采用室内盆栽试验,在正常供水(80%田间持水量)、中度干旱(50%田间持水量)、重度干旱(30%田间持水量)条件下分别接种丛枝菌根真菌(AMF)、植物根际促生菌(PGPR)、AMF+PGPR联合接种及不接种处理(CK),测定玉米叶绿素含量、气体交换参数、营养元素吸收、活性氧代谢、内源激素含量以及单株产量的影响。结果表明,正常供水、中度干旱、重度干旱下接种PGPR均可以增加AMF菌根侵染率,接种AMF可以增加PGPR定植数量,二者具有协同作用,重度干旱胁迫下AMF+PGPR联合接种处理的AMF侵染率较AMF处理提高34.6%,PGPR定植数量较PGPR处理提高31.3%;重度干旱胁迫下,与CK相比,AMF+PGPR联合接种的玉米叶绿素a、叶绿素b、总叶绿素、类胡萝卜素含量分别增加14.4%、95.5%、22.2%、42.2%,净光合速率、气孔导度、蒸腾速率较CK分别增加28.9%、23.9%、42.8%,胞间CO2浓度降低8.6%;与正常供水相比,中度干旱、重度干旱胁迫下玉米根系和茎内氮、磷、钾含量总体表现为下降趋势,且表现为茎>根系,重度干旱下AMF+PGPR联合接种的玉米根系氮、磷、钾含量较CK分别增加5.2%、18.5%、19.0%,AMF+PGPR联合接种的玉米茎内氮、磷和钾含量较CK分别增加34.9%、6.8%、13.9%;重度干旱胁迫下,玉米叶中超氧化物歧化酶(SOD)、过氧化物酶(POD)活性下降,丙二醛(MDA)和过氧化氢(H2O2)含量增加,其中AMF+PGPR联合接种的SOD、POD活性分别增加26.9%、354%,MDA、H2O2含量分别下降26.3%、28.6%;重度干旱胁迫下,AMF+PGPR联合接种还能增加生长素(IAA)和脱落酸(ABA)含量,IAA、ABA含量较CK分别增加9.0%、10.3%,AMF+PGPR联合接种的玉米百粒重和单株产量较CK分别增加3.2%、26.8%。可见,对于干旱严重制约作物生产的地区而言,AMF+PGPR联合接种为提升玉米产量更具前景的田间管理策略。
