People have paid attention to the pollution of soil and water quality caused by using organic arsenic chemistry reagent to prevent and cure apple-tree canker in our apple area, so it has an important purpose to seek a harm-free way for sustaining development of apple. The tests studied the effect of prevention and cure on apple-tree canker with EM mud, EM liquid, 40%'Fumeishen powder' and contrast. The results showed that the EM mud was superior to the EM liquid, 40% 'Fumeishen powder' and contrast. The prevention and cure effects of EM in 2006 and 2007 were 92.7% and 93.5%, while the recurrence rates of canker scars 1.8% and 2.8% respectively. And the healing effect of scar is 50.4%. So, it was considered as a new way to prevent and cure apple-tree canker with EM mud.
中国各苹果主产区果农长期使用有机砷等化学制剂防治腐烂病,对土壤、水质等环境造成的污染已引起人们的关注,寻求无公害的方法防治腐烂病,对苹果业可持续发展具有重要意义;本试验设EM活性菌泥涂抹、EM活性菌液涂抹、40%福美砷可湿性粉剂50倍液刮涂和对照(只刮除腐烂病疤,不涂药)4个处理,三次重复,进行了苹果树腐烂病的防治研究;结果表明,EM活性菌泥在防治效果、病疤复发率和促进病疤愈合效果方面均优于其它处理,其当年和第二年4月的防治效果分别为92.7%、93.5%,病疤复发率分别为1.8%、2.8%,促进病疤愈合效果也最好(50.4%);因此,作者提出,将EM活性菌融入粘泥载体中制成菌泥,涂抹在腐烂病疤上,以菌治菌,是防治苹果树腐烂病的新途径。
