1972、1973年我所搞了6个土豆简易沙层贮藏窖,每年贮土豆近万斤。这种贮藏法的优点是①省工、省料,不用窖木、秫秸,从入窖到开窖,120天不用倒个。⑦温、湿度稳定,损耗小,据开窖时(3月16日)窖内15厘米深处温度始终保持在2℃(贮藏适宜温度2～4℃),沙层中间湿度保持在73～74％。由于温湿度适宜,一般年份“男嚼”品种损耗不到5％,“丰收白”不到2～3％,水分大的“红眼圈”也不超过10％,“克新一号”损耗只有1～2％。 1972, 1973, I made a simple potato sand storage cellar 6, nearly 10000 pounds of potatoes each year. The advantages of this storage method is ① labor-saving, material-saving, without cellar, straw, from the pit to open pit, 120 days do not have to pour one. ⑦ temperature and humidity stability, low loss, according to the opening of the pit (March 16) 15 cm deep inside the pit temperature is always maintained at 2 ℃ (storage temperature 2 ~ 4 ℃), the middle layer of sand to maintain the humidity in the 73 ~ 74 %. Due to the appropriate temperature and humidity, the average annual “chewing” varieties less than 5% loss, “harvest white” less than 2 to 3%, water, “red eye” is not more than 10% 1 ~ 2%.
