健薯、适温是安全保存甘薯种薯,防止烂薯烂窖的技术核心。一、健薯系指秋季从田间收获的无病虫、无伤、无冻、未受水淹过的种薯。二、适温甘薯在15℃以上开始萌发,高温条件下还易染病;9℃以下开始受冷害,受冷种薯易遭致软腐病害的发生发展。秋季气温是从高温逐渐转为低温,种薯在贮藏过程中的生理活动——呼吸放热也是从强转弱。15℃以下可抑制甘薯病害的发生,10℃以上可防冷害及
Sweet potatoes, suitable temperature is safe to save the sweet potato seed, rotten pot to prevent the technical core. First, the sweet potato refers to the harvest from the field in the autumn without pest, no injury, no freezing, not flooded seed. Second, the sweet potato temperature above 15 ℃ began to germinate, high temperature conditions are also susceptible to disease; below 9 ℃ began to suffer cold damage, susceptible to cold seed potato susceptible to the occurrence of soft rot disease development. In autumn, the temperature gradually changed from high temperature to low temperature. Physiological activity of seed potato in storage process was also weakened from exothermic respiration. Below 15 ℃ can inhibit the occurrence of sweet potato disease, 10 ℃ or more can prevent cold damage and
