陈稻种发芽势弱,发芽率一般在60%左右。实践证明,隔年乃至两年的陈稻种在生产上是可以利用的,其关键是掌握浸种催芽技术。1、采用温水、活水间歇浸种。这种浸种方法能汰除种子中的泥沙及其呼吸过程中产生的有毒物质,不致影响根、芽的生长。具体做法是:种子清洗消毒后,倒入盛有45℃左右温水的桶或缸内并拌匀,使温度稳定在35℃左右,然后在桶或缸上覆膜保温,晚上浸,白天沥,重复一两 Chen rice seed germination weak, germination rate is generally about 60%. Practice has proved that the next year or even two years of rice in the production is available, the key is to master the soaking seed germination technology. 1, the use of warm water, live water intermittent soaking. This seed soaking method can eliminate the sediment in the seed and the toxic substances produced in the process of respiration, and will not affect the growth of roots and buds. The specific approach is: seed cleaning and disinfection, poured into a barrel or cylinder filled with warm water at about 45 ℃ and mix well, the temperature stabilized at about 35 ℃, and then covered in the barrel or cylinder insulation, immersed at night, leaking during the day, Repeat one or two
