青贮玉米生物产量与植株主要农艺性状相关的研究

Correlation Study on the Main Agronomic Characters of Plant and Organism Yield of Silage Maize

以区域试验的青贮玉米品种为供试材料,通过对各青贮玉米品种的区试生物产量结果进行方差分析和农艺性状与生物产量的相关分析,表明株高、采收期日数和穗位是影响产量的主要因素,提出选择综合农艺性状好的品种是提高青贮玉米生物产量的有效途径。

The silage maize of area experiment was tested by analyzing many k inds of maize and the correlation analysis between yield and main agronomic char acters of plant. The result showed that the main contribution to the organism yi eld was from plant height, ear position and number of days of harvestry date. Th e effective way of increasing silage maize organism yield was to select silage m aize with good agronomic characters.
