花生茎腐病,是我国北方花生产区的一种重要病害,调查证明花生种由于收刨、晾晒不及时或贮藏保管不当,造成霉捂,是诱发花生茎腐病发病的主导因素,因此,群众有“种子捂了死到老”的说法。霉捂的花生种为什么能加重茎腐病的发生,其发病机理尚不清楚.为此,我们对花生种霉捂后诱发花生茎腐病的机制作了进一步的研究,现将结果报导如下:一、材料和方法(一)霉捂花生种带菌量的测定1、材料:供试品种,两年均用伏花生.1977年,试验用霉捂花生系临沭县夏庄公社农技站提供,对照种(不霉捂,下
Peanut stalk rot disease is an important disease in flower production area of northern China. Investigation shows that peanut species are the dominant factor in inducing the occurrence of stalk rot in peanut due to the untimely storage or improper storage and storage of peanut seeds. The masses have “seed cover dead to old” argument. Therefore, we have further studied the mechanism of peanut stalk rot induced by moldy covering of peanut, and the results are reported as follows: Materials and methods (a) Determination of bacteria covered with peanut species 1, material: the test varieties, perennial use of peanut in 1977, the test with moldy peanuts Department Shunshu County Xiazhuang commune farm station provides , Control species (not mold cover, under
