摘要
分析再生稻不同节位分蘖穗与产量之间的关系 ,结果表明 :不同节位分蘖穗与产量间的差异达极显著 ,对产量的贡献大小依次是倒 2节 >倒 3节 >倒 4节 >倒 5节。用不同经验模型分析比较 ,y=114.0 2 - 2 0 .72 x的理论值与实测值较为一致 ,相关关系为极显著。
The analysis of the relationship between grain output and inverse node of ratooning rice shows that the yield variance reached the most significant level and the contribution of inverse node for output ranked as the 2nd inverse node reserved>the 3rd one>the 4th one>the 5th one. After comparison of different models, the model of y=116.58-21.68x is consistent with the fact and its correlation coefficient is most significant.
