洋麻炭疽病的种子消毒处理,在現有方法中,虽以冷水溫湯浸种为最好,但杀菌效果仍不能彻底,效果也不稳定。試驗証明,預浸后种子的含水量是决定溫浸效果的关鍵性因素。一般种子在20℃的冷水中預浸12小时,含水量由10%增加到40%,以后在50℃的温水中处理15分钟或52℃处理10分钟,就可获得彻底杀菌的效果。随着預浸时間的延长,种子的含水量相应增加,同时种子間含水量的差异也逐漸减少,更易达到彻底的目的。种子成熟度的不同和保藏情况对种子的吸水速度也有很大的影响,尤以晒种的作用更为明显。种子在处理前晒种1小时就显著減低种子的吸水速度,从而影响种子处理的效果。
Seed germination of anthracnose in the current method, although the best soaking cold water temperature soup, but the bactericidal effect is still not completely, the effect is not stable. Experiments show that the water content of pre-soaked seeds is the key factor to determine the effect of temperature-soaking. The general seed is pre-soaked in cold water at 20 ° C for 12 hours, the water content is increased from 10% to 40%, and then the bactericidal effect can be obtained by treating in warm water at 50 ° C for 15 minutes or at 52 ° C for 10 minutes. With the prolonging of prepreg time, the water content of seeds increases correspondingly, meanwhile, the difference of water content between seeds also decreases gradually, which makes it easier to reach a thorough goal. The differences in seed maturity and preservation have also had a significant impact on the rate of water absorption by the seed, especially in the sunburn. Seeding seeds for 1 hour before treatment significantly reduces the rate of water absorption by the seeds, thereby affecting the effectiveness of the seed treatment.
