1.选、晒种子人工挑选或用筛子筛选,剔除小粒、病粒、杂粒。把选后的种子摊在炕席上或塑料布上,在烈日下暴晒2~3天,以提高种子活力。 2.父本催芽将父本种子用清水洗两遍,置于30~35℃的温清水中浸泡8~10小时,待种子吸足水分捞出,装入盆内,放在20~25℃的火炕上,隔2~3小时翻动一次,经24小时有一半 1 election, sun seed artificial selection or screening with a sieve, excluding small particles, sick tablets, miscellaneous grains. After the election of the seeds on the kang mat or plastic sheeting, in the hot sun 2 to 3 days, in order to improve seed vigor. 2. The male parent germinates the male parent seed twice with clean water and soaks it in warm and clear water at 30-35 ° C for 8-10 hours. After the seed has absorbed enough water to remove it, put it in a bowl and place in a temperature of 20-25 ° C On the kang, every 2 to 3 hours flip once, after half an hour in 24 hours
