摘要
对不同密度下的玉米株高整齐度与德部性状的相关分析表明，玉米株高整齐度随密度的提高而降低，株高整齐度与穗长、行粒数、穗粒数、单穗重和穗粒重均呈极显著正相关，与秀尖呈极显著负相关，相关程度：行粒数＞秃尖＞穗长＞单穗重＞穗粒重＞穗位数。生产上可以通过栽培措施的标准化，提高玉米株高整齐度，实现丰产稳产的目的。
Correlation analysis was done between plant height consistency and ear characters in maizewith different densities. The results show that: plant high comisteny decreases as density rises. Thecorrelation is most significance positive between plant height consistency and eat characters including ear length, the numbers of row kemels, ear kemels, the ear weight, the ear kemels weight and the numberof ear kemels. The correlation is most significance negative between plant height consisteny and ear baldlength. Significance levels is the number of row kemels > ear bald length > ear length > ear weight > earkemel weight> the number of ear kemel. In production, high and stable yield will be obtained whenplant height consistency is raised by standard cultivation.
