摘　　要：通过盆栽试验,研究了复合菌肥对锌污染土壤中油菜生长的影响。结果表明:在一定量的锌浓度下,油菜鲜重、叶绿素a、叶绿素b、叶绿素a+b含量均随复合菌肥用量的增加而升高,而油菜锌含量则随复合菌肥的增加而下降。并且叶绿素a+b含量、叶绿素a/叶绿素b与锌在一定浓度范围内也存在一定的负相关。The effect of combined bacterial manure to rape growth in soil polluted by the Zinc was studied through pot experiment. The results showed that： with a certain density of zinc in soil, the weight of fresh rape and the chlorophyll a, chlorophyll b chlorophyll a ＋ b content of the rape rise along with the increasing use of compound bacterium fertilizer; on the contrary, apart from the above with a certain zinc density in soil, the content of chlorophyll a ＋ b, chlorophyll a or chlorophyll b is inversely proportional to that of zinc.
