杂交稻春季或夏季繁殖制种,在成熟期,若遇连续几天阴雨或大雾的影响,造成穗上发芽,种用价值严重降低。如果浸种与催芽的方法不当,发芽率更低,甚至全部不发芽。经我站试验,芽谷粒率达30.51%的协优辐26种子,采用煤渣灰催芽法。发芽率达60.44%,不仅比精心管理的常规浸种催芽法的发芽率提高15.94%,达极显著标点,根长与芽长分别长60.28%与41.36%,而且是一种安全可靠、操作简便,易于千家万户农民掌握应用的催芽法。煤渣灰催芽操作方法:把种子放入清水中反复搅动淘汰,捞去浮在水面的空壳、瘪谷等杂质后,将种子
Hybrid rice in spring or summer seed production, in the mature period, if the case of rain or heavy fog for several days, resulting in ear sprouting, the value of serious decline. If soaking and germination improper method, the germination rate is lower, or even do not germinate. After my station test, the bud grain rate of 30.51% of 26 hybrid seed, the use of coal ash sprout method. The germination rate reached 60.44%. Compared with the well-managed conventional soaking germination method, the germination rate was increased by 15.94%, reaching a very significant punctuation. The length of the root and the bud were 60.28% and 41.36% respectively. Moreover, it was a safe, reliable and easy- It is easy for thousands of farmers to master the application of germination method. Cinder ash sprouting operation method: the seeds into the water repeatedly stirred out, fishing to float the surface of the shell, deflated Valley and other impurities, the seeds
