我队在渭河北沿,每年在河滩地插红薯150～200亩,占滩地面积的1/3左右。过去,没有解决好薯种的安全贮藏问题,总是从外地购买薯苗,投资大、质量低,插后缓苗期长,成活率低,产量不高。有些生产队曾在地下挖2～2.5米深的井窖贮放,因地下水位高(雨季1.5米左右,冬、春季2.5～3米),窖型不合理,窖内湿度过大,温度偏低,通气不良,一般在春节前就发生烂窖。实践证明,这种窖只能短期贮放食用红薯,而解决不了种用红薯的安全贮藏。为了解决这一问题,我们学习
My team is along the Weihe River, sweet potato every year in the floodplain 150 ~ 200 acres, accounting for about 1/3 of the beach area. In the past, the problem of safe storage of potato seed was not solved. Potato seedlings were always purchased from other places. The investment was large, the quality was low, the seedlings were slow after plugging, the survival rate was low, and the yield was not high. Some production teams had dug underground wells 2 to 2.5 meters deep for storage. Because of the high groundwater level (about 1.5 meters in the rainy season, 2.5 to 3 meters in winter and spring), the pit type is irrational, the humidity in the pit is too large and the temperature is too high Low, poor ventilation, usually occurs before the Spring Festival rotting cellar. Practice has proved that this cellar only short-term storage and consumption of sweet potatoes, and can not solve the safe storage of sweet potatoes. In order to solve this problem, we study
