摘要:
为指导玉米新品种克玉19合理密植，在种植密度6.00万~9.75万株?hm-2，按照梯度0.75万株?hm-2设6个密度处理，研究不同种植密度对玉米产量及其构成因素的影响，探讨克玉19的最佳栽培密度。结果表明：随着密度增加，产量先增后减，空秆率、秃尖增加，穗长、穗粗、行粒数、穗粒重、百粒重减少，株高、穗位升高，穗行数影响较小；克玉19在中等肥力水平下，适宜种植密度为8.25万株?hm-2左右。
Abstract:
In order to guide the rational close planting of the new maize variety Keyu 19，six planting densities were set according to the gradient of 7 500 plants?hm-2 at the range of 60 000 to 97 500 plant?hm-2，and study the effects of different planting densities on the yield and its composition factors,and discuss the optimum planting density of Keyu 19.The results showed that with the density increasing,the yield first increased and then decreased,the ratio of empty stalk and bald tip all increased,while the ear length,ear diameter,grain number per row,ear grain weight and 100-grain weight decreased,the plant height and ear height increased,and the grain number per row was relatively stable.The optimum planting density of Keyu 19 was 82 500 plants?hm-2 under middle fertility level.
