柽麻是南阳地区主要的夏播绿肥,生长快,适应性广。近年来,有些地区柽麻在生长期植株发病凋萎枯死,形成大片缺株,致使种子产量下降,对柽麻的大发展威胁极大。为了摸清这种病害,寻求有效防治措施,我们于1977—1978年作了一些研究工作。现将研究的部分结果简报如下。 Ma flax is the main summer sowing green manure in Nanyang, which grows fast and has wide adaptability. In recent years, in some areas, flax plants withered and wilted in the growing season, forming a large number of missing strains, resulting in a drop of seed yield and a great threat to the great development of flax. In order to find out the disease and seek effective prevention and control measures, we made some research work in 1977-1978. Now part of the research results briefed as follows.
