| 摘 要： | 采用生育期与枯心率随机区组排列、人工模拟螟害试验．试验结果表明，水稻在低叶位时比高叶位的分蘖补偿能力大；随着生育期增大，随着模拟枯心率增大，每株有效穗呈逐渐减少趋势；水稻增大实粒数和千粒重来达到产量补偿，并且其补偿率随叶龄的增大而增长．产量是补偿能力的综合体现，低叶龄期受低螟害，水稻对产量损失有补偿能力

| Abstract: | Two factors of the compensation of yield loss random block experiment was carried at Sihui City in 1986 The results showed that the compensation capacity of tillers on lower position was larger than that of tillers on higher position In the middle and the late tillering stage, following the reduction of capability of tillering, the effective ear has been found to be reduced too The compensation of yield loss by enlarging the filled percentage and 1 000 grain weight, the older the ages of leaves, the highter the percentage of compensation The yield of rice was integrated results of the compensation and the rice has the compensative capability to the yield loss, while the damage of stem borers was lower density during the early stage |
