食用根类作物种子的春化处理若干食用根类作沏(如胡蘿卜、甜菜、根用洋芫(?))的种子出芽乃是很慢的。为了使幼苗早日出土和促进以往植株的发育,应该对种子进行春化处理。胡蘿卜种子经过春化处理,可比乾的、未经过春化处理的种子早5—8天出土,或比濕的、未经过春化处理的种子早3—5天出苗,同时经过春化处理的种子,以后植株的生长也将会显得十分盛旺,并且可以获得较高的收穫量。比如,莫斯科州希米金斯克中学的少年实验家们,使用经过春化处理的种子曾在1946年获得了比用普通种子多達两倍的产量。加里宁州少年自 Vernalization of edible root crops Seeds germinated slowly by several edible root crops such as carrot, sugar beet, and rooted with cilantro (?). In order to early excavated seedlings and promote the development of previous plants, the seeds should be vernalized. After vernalization, the carrot seeds could be excavated 5-8 days earlier than the un-vernalized seeds, or germinated 3-5 days earlier than the vernalized seeds and vernalized Seed, the future growth of plants will also be very prosperous, and you can get a higher yield. For example, juvenile laborers at the Shiminsk High School in Moscow, using vernalized seeds, achieved up to twice as much fruit in 1946 as seeds used for planting. Kalining teenager since
