杂交稻的优势,最为突出的首先表现在生长优势上。据我们多年考察,除穗颈节外,几乎每个茎节尤其是基部密集节上的休眠腋芽,一旦遇到适宜的生态条件均可萌发为新生蘖苗。我们于1977—1978年在海南试验蘖苗育秧,将籼型杂交稻大田用种量降低到0.5斤(曾获地区农学会科技成果奖)。198 The advantages of hybrid rice, the most prominent first manifested in the growth advantage. According to our many years of investigation, in addition to the panicle neck section, almost every stem section, especially on the base of the dense section of the axillary buds sleep, in the event of appropriate ecological conditions can germination of new tillers. We tested tillers and seedlings in Hainan from 1977 to 1978 and reduced the seedling yield of Indica hybrid rice to 0.5 kg (won the Science and Technology Achievement Award of the Regional Agricultural Association). 198
