摘　　要：对2005年早稻的不同移栽方式进行了比较研究,揭示并阐明了抛秧早稻的生态生理特征如下:秧苗带土抛秧不伤根,返青快,促进了水稻分蘖的早生快发,以及有效穗的形成;抛秧水稻的单株叶面积要低于手插稻,但是群体的叶面积指数高,提高了水稻群体的光合速率;抛秧稻的根数、根重、根系活力都要比手插稻的显著要高,为水稻的灌浆结实积累了大量的物质。抛秧稻最终获得超高产的有效途径是在有效穗,穗粒数提高的前提下,保证结实率不下降。Research the effect of the two different transplant on the early-rice in 2005 year. Illuminate the ecology and physiology characteristic of the throwing-transplanted rice as follows： The throwing-transplanted rice with some soil couldn＇t hurt the root, and accelerate the paddy tiller, as well as the formation of the spike. The community＇s leaf area index of throwing-transplanted rice is higher than the hand-transplanted rice paddy ,athough individual plant leaf area index of throwing-transplanted rice is lower. Meanwhile the root number, the weight of the root and the root system vigor of the throwing-transplanted rice is also higher than the hand-transplanted rice. Those enhanced the paddy rice community＇s photosynthesis speed, and accumulate massive matter for the paddy rice＇s grouting. Ensure throwing-transplanted rice obtain the super-high yield, Enough effective spikes and grains enhance, under the premise guaranteed the fertility does not drop.
