木麻黄青枯病是威胁木麻黄生长的一种严重病害。七十年代初期,我区的新海、岛东林场仅发现零星病株,以后蔓延成块状分布,至1978年发病面积达5000—6000亩,严重病区达1000—1500亩。这些病树都是10年生左右,尚未达到工艺成熟期.为此,我们从1976年起就进行调查观察,1977年在新海林场和岛东林场进行了防治试验.现将结果报道如下:
Casuarina is a serious disease that threatens the growth of Casuarina equisetifolia. In the early 1970s, only a few sporadic diseased plants were found in the Xinhai and Donglin Forest Farms in our area, spreading to lumpy distributions later in 1978, with a disease area of 5000-6000 mu in 1978 and a serious ward of 1000-1500 mu. These trees are about 10 years old and have not yet reached the maturity of the process.To this end, we conducted a survey from 1976 onwards, in the control of the new Hailinchang and East Forest Farm in 1977. The results are reported as follows:
