摘　　要：试验结果表明,叶康能使病毒病症状消失,使叶片形态恢复到正常,从而使叶片光合面积增加。喷施浓度为800倍、1000倍、1200倍叶康以后,改善番茄病毒病症状的效果为90.6%～96.6%,增产16.6%～43.3%;改善甜椒病毒病症状的效果为83.8%～95.2%,增产33.0%～125.2%;试验结果还表明,叶康还能使烟草、黄瓜、番茄叶片中的叶绿素含量增加,减少烟叶中烟草花叶病毒的含量。The experimental results showed that Yekang would make virus disease symptoms disappear and make the shape of leaves resume normal, and then increase the illumination area. By sprayed Yekang concentration at 800, 1000, 1200 fold respectively, the effect on preventing tomato virus disease was 90.6%~96.6% and increase the yield of per unit area by 16.6%~43.2%; effect on hot pepper virus disease was 83.8%~95.2%, the yield increased by 33.0%~125.2%. Experimental results also showed that Yekang could add to the chlorophyll content of tobacco leaf,cucumber,tomato and reduce the TMV content of tobacco leaf.
