摘 要 ：本文研究了在甘蔗分蘖末期喷施稀土对甘蔗植株ATP酶和根际土壤酶活性以及根际细菌数量的影响。结果表明，分蘖末期喷施稀土提高了甘蔗叶片的Mg2+-ATP酶、Ca2+-ATP酶和根细胞的Na+-K+ATP酶的活性。提高了叶绿素含量、光合还礼经和根系活力，使土壤中有益的根际细菌数量增加，土壤酶活性提高，促进了甘蔗生长，提高了甘蔗产量。

Abstract:Effect of rare earth spraying at the end of tillering phase of sugarcane on activities of ATPase and enzymes in the rhizosphere was investigated. The results suggested that rare earth spraying at the end of tillering phase increased the activities of Mg2+-ATPase and Ca2+-ATPase in sugarcane leaves a
