本文以平邑甜茶(Malus hupehensis Reld),平顶海棠(M. prunifolia Bork)和新疆海棠(M. sieversii Roem)三种苹果常用砧木苗为试材,采用分层取样的根际箱法对其根际微域的环境状况进行了研究。结果表明,根际微域pH和氧化还原电位(Eh)下降,N、P、K表现根际亏缺,Ca和Mg在报表积累。根际影响范围多为2-3mm,有时可达4-5mm。果树根际环境状况随砧木不同而变化,表现出种间差异。
The environment and nutrient status of the rhizosphere were studied using three apple rootstock seedlings, Malus hupehensis Reld, M. prunifolia Bork and M. sieversii Roem. The results showed that pH and Eh decreased and N, P and K were depleted in the rhizosphere compared with the bulk soil. Ca and Mg were enriched in the rhizoplane. The rhizosphere range of apple rootstock seedlings was mostly about 2-3mm from root surface, sometimes it might reach to 4-5mm. Results also showed that different species had different environments and nutrient status of the rhizosphere.
