柽麻是我省的一种主要夏季绿肥,不仅生长快、养分高,适应性广.而且从3月到8月都可利用不同茬口播种或套种、间种,一般生长40—50天即可加以利用.多年来培肥改土对我省农业增产起了一定的作用,深受群众欢迎.因此,从五十年代初引进我省后,发展很快,至1976年已发展到200多万亩.但是,自1977年起,我省一些地方的柽麻开始发生不同程度的病害,主要是镰刀菌属的枯萎病.我们自1978年起开展柽麻枯萎病的病源、传播途径及防治措施等方面的试验研究工作. 一、柽麻枯萎病症状和病源菌的鉴定
It is not only fast growing, high nutrient, wide adaptability, but also can be used from March to August to seeding or intercropping with different stubble crops, usually growing for 40-50 days To make use of.Marine and soil improvement over the years on agricultural production in our province played a certain role, welcomed by the masses.So, from the early 1950s after the introduction of our province, the rapid development until 1976 has grown to more than 200 million Mu. However, some diseases began to occur in some areas of our province, mainly Fusarium wilt disease, in some parts of our province since 1977. We have carried out the pathogen, transmission route and control measures of Fusarium Wilt since 1978 And other aspects of the experimental research.First, the symptoms of fusarium wilt and identification of pathogenic bacteria
