一、热如催芽温度太高,易造成种子吃热,引起死亡。使用保温瓶和电灯保温方法催芽,常易发生这种现象,原因是靠开闭瓶塞调节水温,往往控温不严格,使种子受热,导致催芽失败。正确的方法是:将瓶塞打个孔,插入温度计。这样,盖紧瓶塞后就能测出准确的温度。利用电灯催芽时,常常由于后半夜电压升高,温度猛升而烫死种子。此外,利用灶头余热催芽时,往往因温度不够而使发芽缓慢或不 First, heat, such as germination temperature is too high, easy to cause the seeds to eat hot, causing death. The use of thermos and light insulation method of sprouting, often prone to this phenomenon, the reason is that by adjusting the water temperature by opening and closing corks, often temperature is not strict, the seeds heated, resulting in germination failure. The correct way is: Make a stopper hole, insert the thermometer. In this way, you can measure the exact temperature after the stopper is capped. The use of electric light sprouting, often due to post-night voltage increases, the temperature soared and burn seeds. In addition, the use of stove waste heat sprouting, often due to lack of temperature so that germination is slow or not
