摘　　要：为培育合格的机插秧苗,观察了水稻幼苗根叶伸长动态。结果表明,N节叶片、N-1节叶鞘、N-3节节根同步伸长;1叶1心期,第一层节根—胚芽鞘节节根萌发伸长,至4叶1心期,共有4节节根及其分枝根萌发,在秧盘底部缠结成网,确保秧苗连片不散,便于带土机插。For cultivating qualified rice seedling by mecnamcm transplanting,thh and N-3 node s nodal root root-leaf was observed. The results showed that N node s leaves, N-1 node s leaf shoat elongated synchronization. At the stage of one mature leaf and one new leaf, the first layer nodal root-coleoptile nodal root were sprouting and growing. At the stage of one mature leaf and four leaves, there were 4 node＇ s nodal root and their branch roots germination, and their entangled into a network at the bottom of seedling plate to ensure the rice seedling contiguous lingers, in order 1o convenient for machine-transplanted with soil.
