通过研究玉米密度与产量以及产量构成因素的关系。结果表明：密度对玉米秃尖长的影响最大，对玉米株高的影响也很大，其次是千粒重、行粒数，对穗长的影响不显著。密度是影响玉米产量的关键因素，攀西地区及其类似地区的玉米高产密度不宜超过87608株／hm2，最佳经济生产密度为80000～85000株／hm2。

The study analyses the relationship between maize planting density, maize yield and yield constitutes factor. The results are: Planting density has greatest influence on the height of plant and the length of bare ear, then the weight of per 1000-grains, grains, grain number of per row. Planting density makes no notable impact on the ear length. Planting density is the key factor influencing yield; the best maize planting density in Pan-xi district and other similar area is 87608 plants/hm2.
