通过对安徽省涡阳、蚌埠、滁州和芜湖调查发现,竹柳病害危害最重的为水泡型溃疡病,病原为聚生小穴壳菌,平均发病率24.63%;竹柳虫害主要有5类:天牛类、柳蓝叶甲、膜肩网蝽、刺皮瘿螨和大青叶蝉,其中天牛类发生最为严重,平均虫株率46.13%。竹柳密度和病害发生率呈负相关关系,但林龄等与病虫害均无较强关系。通过对竹柳进行不同施肥处理,得出L4-4处理下的竹柳胸径最大,为10.26 cm,病虫害与对照相比明显减轻。
According to the survey of Guoyang, Bengbu, Chuzhou and Wuhu in Anhui Province, the most harmful species of birch will be vesicular canker, the pathogen is Polygonatum, the average incidence rate is 24.63% Cerambycidae, Diabrotica aureus, Schizochytrium scapuloidea, Spider scabies and Dictyopteris, the most serious of which were Bees and Caterpillars, with an average rate of 46.13%. There was a negative correlation between the density of bamboo and the disease incidence, but there was no strong relationship between age and other pests and diseases. Through different fertilizations of bamboo willow, it was concluded that the diameter at breast height of bamboo under L4-4 treatment was 10.26 cm, and that of pests and diseases significantly reduced compared with the control.
