摘　　要：稻株个体生长障碍是水稻再高产的限制因素，优化基本苗群体（秧田、本田）是消除或减少稻株个体生长障碍的有效措施，试验证明，采用带蘖大苗，单本稀植后，可以通过大幅度提高稻株个体分蘖力和分蘖成穗率来稳定高产栽培的穗群体。通过提高个体质量，使平均穗粒数增加１０粒以上，结实率提高５％以上，从而使籽实产量提高１５％以上而获得超高产量。Individual growth obstacle is a limit factor of super high yield of rice plant.Optimizing seedling population is an effective measure for removing or reducing individual growth obstacle.The experiment results showed that the spike population for high yield could be stabilized by increasing tillers and heads through aged seedling with tillers and transplanting sparsely with only one plant a hill.Since the quality of individual plant was ameliorated,the average spikelets per ear increased more than 10,seed setting rate increased by 5 percent,therefore,grain yield increased by 15 percent,and got super high yield.
