“AB型增粒剂”是一种能够显著提高杂交稻繁制异交结实率的最佳新型制剂。经多年多地试验证明,运用“AB型增粒剂”后: 1.能够刺激穗下第一、二节间的迅速伸长,从而使不育系包颈程度大为减轻,有效颖花数提高,尤其是穗下节的伸长十分显著。 2.能促进花时提早,开花集中,增大开颖角 “AB-type granule-raising agent” is a new type of preparation that can significantly improve the outcrossing rate of hybrid rice. After many years of testing to prove that the use of “AB-type granulation agent”: 1. Can stimulate the ear under the first and second section of the rapid elongation, so that sterile lines greatly reduce the package neck, the effective number of spikes Increase, especially the next section of spike elongation is very significant. 2. To promote early flowering, flowering, increased open angle
