摘要
本文研究了介质中铁、盐、和根际ｐＨ值对苹果最适生长条件及叶片失绿的关系。结果表明，当介质中盐、水平较低时（ＮａＣｌ＜０．０９％～０．１７％，＜２０３～４１０ｍｇ／Ｌ），根际ｐＨ值显著下降，植株不失绿。高ｐＨ值和低铁水平抑制植株的生长，但可诱使植株根系分泌质子、降低根际ｐＨ值，提高植株对碱和缺铁的适应力。
A study was made of the relations of iron,salinity. and rhizophere to the most suitable conditions for the growth of apple trees andd to chiorosis of leaf. The resultswere that lower rhizophere pH and no chlorosis were measured in lower levels of salinityaiid conditins(NaCl<0.09%～0.17%,<204～419 mg/). Higher pH andlower iron in solution can effect the growth of fruit trees,make roots secrete H￣+,decreaserhizophere pH and increase resistance to soda and Fe一stress
