摘要: 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

关键词: 玉米, 密度, 玉米产量, 产量构成因素

Abstract: 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.

Key words: MAIZE, PLANTING DENSITY, MAIZE YIELD, CONSTITUTE FACTOR OF YIELD
