Abstract: 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.
