摘要
对三种不同播种密度的旱育秧和湿润育秧苗根系进行比较研究，结果表明，旱育秧苗根系在不定根总数、白根数、分枝根数、发根力、根系活力及干物质积累等方面均占有明显优势，更有利于增强秧苗抗逆性和适应性。
In this article, the authors studied the root systems field of the three kinds of dry breeding and wet breeding seedlings of different planting density. The result showed that the root systems of the dry breeding seedlings were superior in the number of the adventitious roots, white roots, branch roots, the ability of root growth, the vitality of root systems and the accumulation of dried materials. Thus, it was good for the strengthening of the resistance and adaptability of the seedlings..
