本文通过氮肥运筹和后期施磷的试验研究，明确了抛秧稻超高产栽培的氮磷运筹技术。即氮肥运筹基蘖肥与穗肥比例５∶５为宜；磷肥在等量基肥前提下，后期施磷有一定效果。运用上述运筹方法，能确保适宜群体动态，增加高效叶面积，提高成穗率、粒叶比和后期光合效率，增加抽穗后干物质积累量，主攻总颖花量夺高产。
In this paper, through nitrogen fertilizer operation and late-stage phosphorus application experiment, it is clear that the technology of nitrogen and phosphorus in super-high-yielding rice throwing rice cultivation technology. That is, the proportion of nitrogenous fertilizer base tillering fertilizer and panicle fertilizer is 5: 5, while phosphorus fertilizer has the same effect on the base fertilizer of the same amount. Using the above-mentioned operational methods can ensure the appropriate population dynamics, increase the effective leaf area, increase the rate of ear, grain-leaf ratio and post-photosynthetic efficiency, increased dry matter accumulation after heading, the main total spike yield high yield.
