随着农村生产责任制的改变,行之有效的高温大屋窖越来越不适应户营为主的生产形式。鲜苕的贮藏几乎又回复到过去的老式窖藏,红苕出窖率因此而降低。我们采取“三改三要”的技术措施改进老式窖贮法,在生产上收到了较好效果,下面对这一技术作一简介。一、改收挖太迟为适时收挖,要严格选苕入窖。收获红苕太迟,遇霜受冻发生冷害,不耐贮藏。我省一般应在霜降开始收挖,立冬前后结束。入窖苕最好在晴天土壤干燥时收挖,土壤过湿可先割藤晾埂后再挖。入窖前严格选苕是安全贮藏的关键。受伤、受冻、受渍、带病和虫蛀的苕块应一律剔除。 With the change of the responsibility system of rural production, the well-established high-temperature large house cellar is becoming more and more unsuited to the form of production mainly dominated by households. Xian fresh storage almost back to the old-fashioned cellar, the rate of red wine out of the pit reduction. We take the “three changes to three” technical measures to improve the old pit storage method, the production has received good results, the following make a brief introduction to this technology. First, the change to dig too late digging timely digging, to be strictly selected 苕 into the pit. Harvest red snapper too late, in case of frost chilling injury, intolerance storage. In our province, the frost drop should start to be collected and the winter and winter ends. Into the cellar 苕 best dry soil in the sunny days when the digging, the soil can be wet first cut the vine and then dig. Strict selection of cellar before the election is the key to safe storage. Injured, frozen, stained, diseased and moth-eaten blocks should be removed.
