猪粪和石灰对矿区污染土壤中芹菜生长及生理生化的影响_农业科学.doc

摘  要

　　　通过盆栽试验，研究了矿区污染土壤上施用猪粪、石灰2种改良剂对芹菜株高、最大叶面积、地上部鲜重、过氧化物酶（POD）活性、维生素C及游离脯氨酸含量的影响。结果表明：（1）施加石灰（除高量）和猪粪时，均能增加芹菜株高、最大叶面积和地上部鲜重，猪粪高量时显著高于对照，石灰高量时的影响表现为抑制；石灰中量时株高显著高于对照。（2）施加石灰和猪粪（除高量），均能增加芹菜POD活性，施石灰时与对照之间差异不显著，施猪粪低量时显著高于对照。（3）施加石灰（除中量）和猪粪时，游离脯氨酸含量显著低于对照。（4）施加石灰（除高量）和高量猪粪时芹菜的维生素C含量显著高于对照。

ABSTRACT

　　Pot experiment was used to study the effects of organic manure and lime amendment on plant height, maximum leaf area, fresh weight of aboveground, peroxidase (POD) activity，content of vitamin C and free proline influence in Celery grown in soil polluted by heavy metals . The results showed that (1) Application of lime (except high amount) and organic manure, can increase the celery plant height, maximum leaf area and fresh weight of aboveground, high amount of organic fertilizer was significantly higher than control, the influence of the amount of lime high performance for the inhibition; middle amount lime in the plant height was significantly higher than control. (2) Application of lime and organic manure (high amount), can increase the peroxidase (POD) activity of celery, lime was no significant when difference between with the control，low levels of organic manure was significantly higher than control. (3) Application of lime (except middle amount) and organic manure, the free proline content was significantly lower than control. (4) Application of lime (in addition to high levels) and organic manure high in vitamin C content of celery was significantly higher than control.
