摘要:
以江单4号为试验材料，在4.50、5.25、6.00、6.75、7.50万株·hm-2五个种植密度下，研究了种植密度对玉米产量和品质及穗部性状的影响。结果表明：玉米的产量随着种植密度的增加先增加后减少，产量在6.75万株/hm2时最高，在4.5～7.5万株/hm2的密度范围内，随着种植密度的增加，蛋白质、百粒重、穗长、穗粗、行粒数、秃尖长度达到显著水平，蛋白质、百粒重、穗长、穗粗、行粒数随之减小，秃尖长度随着种植密度的增加而增加；玉米的淀粉含量、脂肪和穗行数没有达到显著水平，说明密度对它们影响不大。
Abstract:
With the test materials of Jiangdan 4，under the planting density including 45.0, 52.5, 60.0, 67.5, 75.0 thousands·hm-2. The effect on the output and quality affected by the planting density, as well the characters were researched. The results showed that with the development of planting density, the output increases a little and then reduces. The output achieves the highest top at 67.5 thousands·hm-2. Accompanying with the increase of planting density, the protein, weight of hundred grain, ear length, diameter and grain number of per row reduced contrarily, on the contrary the length of bare tip increased more. There is not significant of starch content, body fat and kernel rows per ear of the corn, which indicates a little effect on it.
