马铃薯窖藏期的腐烂,在武威地区普遍发生,特别是在收获期遇到阴雨,或灌水过多,入窖后腐烂更为严重。 我所于1964—1965年进行“401”防治马铃薯的烂窖试验。 供试品种为洋白、深眼窝,薯块入窖前进行严格挑选,入窖后10天施药,进行窖内熏蒸,窖温在14℃以下。密闭4天,其后30天检查腐烂率。用药量每千斤薯块分别为80、70、60、50、30、20毫升。试验结果:腐烂率依次为1.75％、1.88％、 Potato cellar decay during the widespread in Wuwei, especially in the harvest encountered rainy days, or excessive irrigation, into the pit after decay more serious. I carried out in 1964-1965 “401” prevention and cure of potato rotten pit test. Test varieties for the white, deep nest, tubers into the pit before the rigorous selection, into the pit after 10 days of application, the pit fumigation, pit temperature below 14 ℃. Airtight for 4 days, followed by 30 days to check the rotten rate. Dosage per kilogram of tubers were 80,70,60,50,30,20 ml. Test results: The decay rates were 1.75%, 1.88%
