近年来本省大小麦在不同地区陆续发现一些影响生产的病害,特别是一些病毒病,除了容易同生理性病害混淆外,在不同病毒病之间,因外表症状类似,更不容易鉴别,因而往往引起不同的看法。如大麦伪条斑病经过试验,业已明确是由种子、花粉或汁液传带病毒的,其主要特征除叶片呈花叶斑驳外,有细小的散生褐色条斑,或较长的褐色条斑;但近年又发现一种大麦病害,叶片上也有褐色条点,常在麦田连片发生,不同的是这种褐色条点是和叶脉平行的。经过1973和1974两年的观察,初步明确这是一种由土壤传带的大麦病毒病,类似大麦条纹萎缩病。现将观察经过总结如下,以供参考。
In recent years, large and small wheat in different provinces of our province have successively discovered some diseases that affect production, especially some virus diseases. In addition to being easily confused with physiological diseases, appearance symptoms are similar and not easily identified between different virus diseases, Cause different views. For example, barley pseudo-leaf spot disease has been tested and it has been clearly transmitted by seeds, pollen or juice. Its main features include fine scattered brown streaks, or longer brown streaks ; But in recent years, a barley disease has also been found. There are also brown spots on the leaves, which often occur contiguously in the wheat fields. The difference is that the brown spots are parallel to the veins. After two years of observation in 1973 and 1974, it was tentatively and initially clarified that this is a barley virus disease carried by soil and resembles barley stripe atrophy. Now the observation is summarized as follows for reference.
