In order to test effects of fertilize for seedlings raised in plastic trays which used for machine-transplant in Hunan province, a comparative experiment was conducted to three different seedling-raising methods, which applying Yanghao brand of fertilizer for seedlings raised in plastic tray (Yanghao fertilizer), common fertilizer and no fertilizer, respectively.Use the low-temperature stress of cold wave with average daily temperature of 4.3℃ ~8.1℃ during seedling raising period to analyze cold-resistant effect of Yanghao fertilizer.The results indicated that in comparison with common fertilizer treatment and no fertilizer treatment, Yanghao fertilizer had higher fertility and more complete nutrients, and the seedlings treated with Yanghao fertilizer had stronger resistance.Applying Yanghao fertilizer also can increase chlorophyll content, improve CAT activity and seedling quality, promote emergence of new tillers, and increase spike number and yield.%为了检验湖南省机械插秧的盘育秧秧盘肥的效果,用秧好秧盘肥、普通肥、不加肥3种育秧方式进行了育秧机插对比试验,利用育秧期间遇寒潮日平均温度4.3～8.1℃72 h的低温胁迫,对秧好秧盘肥育秧耐寒的田间效果进行了分析.结果表明:秧好秧盘肥育秧比普通施肥盘育秧和不加肥盘育秧的肥力水平高、养分齐全,秧苗抗逆性强,采用秧好秧盘肥育秧还可增加叶绿素含量,增强CAT活性,提高秧苗素质,促进秧苗早生快发,并有增穗增产效果.
