呼市蔬菜公司冷藏蒜苔病害种类初步鉴定和防治处理意见

A Preliminary Identificaton of Gartic-boltings Diseases During Cold Storage in Huhehot and Their Prevention

本文首次明确呼市蔬菜公司菜库在冷藏期间造成蒜苔严重腐烂和损失的主要病害种类。根据诱发产生的病原物镜检,初步鉴定主要是青霉菌(Penicillium sp.)占病斑数的33％,丝核菌(Rhizoctonia sp.) 占病斑数的30％,疫霉菌(Phytophthora sp.)占病斑数的10％,未产生病征的病斑占27％。对冷藏蒜苔发病后可能造成的危害程度和最大贮存期限的估测,提出以湿腐的流行速度和从有效积温予测的探讨。并对冷藏蒜苔控制病的发展提出了防治建议。

Three types of mold diseases which caused important watery rot and severe damage during cold storage and transit in Huhehote, and their causal organisms were first recognized, the diseased samaples were abtained from a cold storehouse of Huhehote Vegetable Company.Identifucation based on careful microscopic observations indicated that in order of decresing importance, as follows: blue mold (Penicillium sp.) 33 per cent of the total lessions, rhizoctonia rot (Rhizoctonia sp.) 30 per cent and shanking diseases (Phytophthora sp.) 10 per cent, the other have not any organisms occurred 27 per cent. The degree of damage due to the watery rot of diseased garlicboltings and its longest time keeped in cold store-house were estimated, and epidemic speed due to the watery rot, effective accumulaed temperature and their significance on forecasting were discussed.And as to the control measures were suggested.
