茄子黄萎病原菌(Verticillium dahliae Kleb.)以厚垣孢子、微菌核和休眠菌丝随病残体在土壤中可存活6～8年,茄子连作栽培黄萎病的发病率高达30%～50%。据我们调查,发生茄子黄萎病的地块一般减产20%～30%,有的甚至绝产。目前,防治茄子黄萎病的方法一是进行嫁接,二是利用药物进行防治。本试验采用硝基·黄腐酸盐溶液早期灌根进行预防,防治效果非常明显。材料和方法一、试验材料试验在莱州市东宋镇潘家村进行。供试品种为济杂长茄,属中晚熟品种。试验采用小区顺序排列对比的方法,每小区定植28株,重复2次。播种期1月10日,分苗期3月15日,定植期4月20日,除灌根
Verticillium dahliae Kleb. Can survive for 6-8 years in the soil with chlamydosporidium, microsaccum and dormant mycelium. The incidence of continuous cropping Verticillium wilt is as high as 30% ~ 50 %. According to our survey, plots of eggplant verticillium wilt generally cut 20% to 30% and some are even dead. At present, the first method of prevention and treatment of eggplant Verticillium wilt is grafting, the second is the use of drugs for prevention and treatment. In this experiment, the use of nitro-fulvic acid solution early irrigation prevention, prevention and treatment effect is very obvious. Materials and methods First, the test material test Laizhou Dong Songzhen Pan Village. Test varieties for the complex long eggplant, is a middle-late maturing varieties. In the experiment, the method of arranging the cells in sequence was used. 28 plants were planted in each plot and repeated twice. Seeding period January 10, seedling stage March 15, April 20 planting period, in addition to irrigation root
