摘要
杨梅根结线虫病是一种新发现的杨梅病害,病原线虫为爪哇根结线虫(Meloidogynejavanica)、南方根结线虫(M.incognita)和北方根结线虫(M.hapla).爪哇根结线虫为优势种.病害的影响因素有果树品种、种植年限、种植方式和土壤pH值.呋喃丹对病害具有防治效果.调节土壤pH值和用客土改良土壤可以减缓病害和促进果树生长.
The disease caused by Root-knot nematodes are recently found on Red bayberry (Myrica rubra Sieb. & Zucc)in Nanan,Fujian. The nematode species were identified as Meloidogyne javanica, M. incognita, M. hap-la. M. javanica is a dominant species in the locality. Factors such as variety, age of orchard, planting pattern and soil pH value influence nematode population development and damage severity. Carbofuran is a effective nematicide in control this disease. Application of lime and soil replacement were suggested to be effective in reducing seriousness of the disease and promoting growth of the fruit trees.
