| 摘 要： | 以2年生脂松苗木为材料,采用盆栽方法研究土壤含水量(干旱和水渍胁迫)对脂松苗木生长和光合特性的影响,旨在为脂松的扩大栽培和管理提供依据.采用6种胁迫处理,即淹水胁迫、100%、80%、60%、40%、20%田间持水量(分别简称为FL、FC、FC80、FC60、FC40、FC20).结果表明,干旱和水涝胁迫都会对脂松的生...

| Abstract: | Two-year-old red pine(Pinus resinosa) seedlings were grown in pots to study the effects of different soil water contents(including aridity and waterlogging stress) on the growth and photosynthetic characteristics of red pine seedlings,in order to provide theoretical foundations for the expanded cultivation and management of red pines.Six kinds of stress treatments were adopted,that is waterlogging stress,100%,80%,60%,40% and 20% of field capacity(respectively called FL,FC,FC80,FC60,FC40 and FC20 for short).... |
