江西绿肥－双季稻超高产种植模式与调控技术研究 ——Ⅰ. 不同移栽方式对早稻生长发育及产量的影响

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。

Jiangxi Green Manure - Double-Crop Rice Super-High Production Technology Pattern and Regulation Method Research ——Ⅰ. Differently transplants influence to the early rice growth and the yield

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.
