“脚腐病”又叫裙腐病,烂蔸病。是柑桔类果树易感染的病害。在我县甜橙(黄果)和温州蜜柑最易感病,金桔、川桔、柚子次之。随着近年我县“温州蜜桔”的大量引种种植,在五、六年至八、九年青壮树上经常发现此病,感病果树根颈部产生水渍状病斑,严重时,病斑绕树杆一圈发展,形成自然“卡脖”,致使树体水、养份失调,叶子发黄,不抽枝梢,不长叶片,逐渐枯死。发病果树根也会腐烂,失去正常生理功能。 “Foot rot” also known as skirt rot, rotten hysteria. Citrus fruit trees are susceptible to disease. In our county, sweet orange (yellow fruit) and mandarin orange are the most susceptible, followed by kumquat, chuanjian and grapefruit. With the recent introduction and cultivation of a large number of Wenzhou tangerines in our county, the disease has been frequently found in green trees of five to six years to eight years and nine years. Waterlogging-like spots are formed on the neck of susceptible fruit trees. In severe cases, Spots around the tree pole in the development of the formation of a natural “card neck”, resulting in tree water, nutrient imbalance, yellow leaves, not pumping branches, not long leaves, gradually dead. Morphological root disease will rot, losing normal physiological function.
