调查了云南马铃薯主产区 17个农户家庭贮存马铃薯的现状和损失。作为商品薯贮存失去商品价值的损失率达到 4 7 4 % ,其中发芽薯占 35 4 % ,损失最大 ,贮存时间 12 0d块茎发芽率仅1 5 % ,但 15 0d迅速增加到 5 6 88% ;破损块茎占 7 2 % ;病害烂薯占 4 8%。马铃薯种薯与商品薯同仓混贮 ,在同样无光照的条件下 ,造成种薯过早发芽 ,而且芽细弱 ,降低了种薯的质量。马铃薯疮痂病 (S .scabies)发生普遍 ,在一些地方发病率高达 10 0 % ,应当引起重视。讨论了马铃薯贮存中存在的问题 ,提出了马铃薯贮存技术发展的意见。
Investigated the status quo and loss of potato stored by 17 rural households in Yunnan’s main potato producing areas. The loss rate of commercial products lost 47.4% of the value of the commodity, of which 35.4% were sprouted and the loss was the largest. The tuber germination rate was only 15% at the storage time of 120 days, but rapidly increased to 56.8% after 15d. Damaged tubers accounted for 72%; disease rotted potatoes accounted for 48%. Seed potatoes and potato products in the same storage and storage, under the same no light conditions, resulting in premature seed germination, buds and weak, reducing the quality of seed. Potato scabs (S. Scabies) occur generally, in some places the incidence of up to 10%, deserve attention. The problems in potato storage are discussed, and the opinions on the development of potato storage technology are put forward.
