洋葱茎线虫在我区未见专门报道和资料,今将我们发现和掌握它在本地区为害情况作如下报道,供有关部门参考。 一、发 现 经 过 一九七八年我校窖藏洋葱几乎全部损坏,经检查病原,发现洋葱大量感染线虫。今年将感染线虫的洋葱进行分离、消毒和接种后,进行种植,发病严重,并于六月中旬引起死亡。对病株和死株进行分离,得到大量活泼的线虫。因此,初步认为线虫的寄生是造成洋葱生病和死亡的原因。在洋葱收获期,我们对呼图壁、昌吉两县进行了普查,发现洋葱茎线虫在上述地区发生极为普遍,并造成不同程度的损失。这是洋葱生产上值得注意的新问题。
Onion stem nematodes in our area no special reports and information, we will now find out and grasp of the situation in the region made the following coverage for the relevant departments for reference. First, it was found that after 1978, almost all the onions in our cellars were damaged. After examination of the pathogen, large quantities of onions were found to infect nematodes. This year will be infected with nematode onions were isolated, disinfected and inoculated after planting, severe onset, and in mid-June caused the death. The diseased and dead strains were isolated, to obtain a large number of lively nematodes. Therefore, the initial thought that parasitic nematodes is the cause of onions caused by illness and death. During the harvest of onions, we conducted a census of two counties in Hutubi and Changji, and found that Onion stem nematodes were extremely common in these areas and caused varying degrees of loss. This is a notable new issue in onion production.
