摘　　要：采用盆栽和田间试验研究特锐菌剂对辣椒疫病的防病效果及对柿子椒的促生作用。结果表明,盆栽试验中,对辣椒疫病的防效可达71.3%,20 d后,株高较对照提高1.71 cm,茎粗较对照增加0.514 mm,叶绿素含量SPAD提高6.317,单位叶片数较对照增加0.86片,叶面积较对照增加0.59 cm^2。田间试验,在定植后施用特锐菌的处理,辣椒疫病的防效可达74.6%,叶绿素含量SPAD提高3.92,株高较对照增加5.79 cm,茎粗较对照增加0.85 mm,增产达35.39%。The pot experiment and field experiment were carried out to study the control effects of Phytophthora blight and plant growth promoting effect of sweet pepper by Trichoderma harzianum. The results showed that,in pot experiments,the control effect reached 71.3%,plant height,thick stems,chlorophyll content were 1.71 cm,0.514 mm,6.317 higher than those of positive control after 20 days,respectively. And leaf number and leaf area were increased by 0.86 and 0.59 cm2 than those of positive control,respectively. In field experiments,the control effect reached 74.6%,chlorophyll content,plant height,thick stems and production were 3.92,5.79 cm,0.85 mm and 35.39% higher than those of positive control, respectively.
