建省以来,邯郸、邢台两地区在平原沙荒、河滩及西部山区营造了大面积刺槐用材林,七十年代初期出现枯梢,而后日趋严重,并有死亡。今年5月,我们对发病严重的漳河和沙河林场进行了重点调查。两个林场共营造刺槐用材林5.7万余亩,其中有5.5万亩发生枯梢病,发病率85.3%,死亡率10.4%(病情见表)。林内多站杆、倒木和频死木,林相残破。 Since the establishment of the province, Handan and Xingtai have created large areas of Robinia pseudoacacia timberlands in plain sandy deserts, floodplains and western mountainous areas. In the early 1970s, there appeared dead shoots which became increasingly serious and died. In May this year, we conducted a survey on the severely affected Zhanghe and Shahe Forest farms. The two forest farms create a total of 57,000 acres of acacia timber, of which 55,000 mu have withered blight, with a morbidity of 85.3% and a mortality rate of 10.4% (see table for the condition). Linzhan more poles, dead wood and dead wood, broken forest.
