摘要： 种蔬菜经沤肥浸渍液(猪粪、马粪、牛粪浸渍液)处理后,黄瓜叶内过氧化氢酶,青椒叶内多酚氧化酶和番茄叶内β-1,-葡聚糖酶活性及黄瓜叶内叶绿素含量与对照相比有明显的增加.青椒叶内苯丙氨酸解氨酶、β-1,-葡聚糖酶活性增幅较小.上述酶活性及叶绿素含量的增高表明植物抗病性的增强,说明沤肥浸渍液对种蔬菜的抗病性具有诱导效应.沤肥浸渍液中,猪粪浸渍液的诱导效果最好.

Abstract: Compost extracts of livestock manure have remarkable preventive function to plant disease.T he paper studies the changes of the chlorophylLcontents and the activity of severaLenzymes inside three vegetables after they have been treated with compost extracts of pig manure, horse manure and cow manure.The experi ment result shows that, compared with the control, the activity of CAT in leaves of cucumbers, of PPO in leaves of green peppers, of 1, 3 dextranase in leaves of tomatoes and the content of chlorophylLin leaves of cucumbers increased obviously;the activity of PAL, 1, 3dextranase in leaves of green peppers increased slightly.T he paper concluded that as the activity of the enzymes mentioned above and the chlorophylLcontents are in positive relation to the disease resistance of plants, the compost extracts of livestock manure have resistance inducing function to the three vegetables and the compost extracts of pig manure is the most effective among the three types discussed.
