山药种薯的保管和出窖时选种的工作,对产量有密切的关系。山药很娇嫩,留种山药窑内温度不能过高,也不能过低。窑藏山药在零下2℃几小时,就会受冻发硬,解冻后表面渗水,不久薯肉就变褐发黑;轻微的短期受冻,皮下也会出现块状干斑。在零下1℃长期低温下,山药不易腐烂,
Yam seed storage and selection of cellars when the work of the output is closely related. Yam is very delicate, stay kind of yam kiln temperature can not be too high, nor too low. Kiln Tibetan yam at minus 2 ℃ a few hours, it will be frozen hard, thawed surface seepage water, and soon the brown potato brown brown; slight short-term freeze, the skin will appear patchy dry spots. At minus 1 ℃ long-term low temperature, yam is not perishable,
