蔬菜种子在播种前进行高温烫种,能增进种子活力,提高发芽率,缩短萌发时间,而且能使其发芽整齐,杀死表面的病原菌和虫卵,从而提高蔬菜产量和品质。 高温烫种一般先浸冷水,后注热水。即将种子盛入容器后,先注入少量冷水,微搅拌,使种子表面都浸湿。随之注入翻滚热水,边倾注边搅拌,使水温迅速升高达70—80℃。约1—2分钟后,将种子
Vegetable seeds hot sowing before sowing, can increase seed vigor, improve germination rate, shorten the germination time, but also make it germinate, kill surface pathogens and eggs, thereby increasing vegetable yield and quality. High-temperature hot first dip cold water, hot water after injection. Immediately after the seed is filled into the container, a small amount of cold water is injected into the container to slightly agitate the seed so that the surface of the seed is wetted. Then poured into hot water, while pouring while stirring, so that the water temperature rose rapidly up to 70-80 ℃. About 1-2 minutes later, seed
