摘要
通过对合肥城区绿化垂柳健康状况的调查,发现其健康状况欠佳。河道边的垂柳受虫害危害最严重,其次是公园垂柳,公路边的垂柳健康状况最好。由于前期的干旱与虫害的作用,死亡数占总数的16.67%,其中河道边的死亡数达到调查死亡总数的25%,公路行道垂柳死亡数占其总数的10%,公园垂柳的死亡数仅仅占0.96%。河道边死亡的垂柳中82.43%有虫害危害症状,而公路边死亡的垂柳中仅仅6.67%有虫害症状。河道边死亡的垂柳主要是干旱与虫害交互作用的结果,公路街道边死亡的垂柳主要是干旱作用的结果。
After the investigation into the health of ornamental willows in Zunyi, we find that the ornamental willows, esp., the willows on the either side of the river, are infested with pest; and the willows on the either side of roads are not so infested with pest. Owing to the drought in the early days and the pest, the number of deaths accounts for 16.67% of the total, and the deaths on the either bank of the river reached 25% of the total deaths surveyed, the deaths on the either side of roads takes up 10%, and the deaths in the parks occupies 0.96%. Of the total deaths on the either bank of the river, 82.43% has the symptom of pest. The deaths of the willows on the either bank of the river are caused by the interplay between drought and pest whereas the deaths on the either side of roads or streets are mainly resulted from drought.
