种植密度对爆裂玉米产量及品质的影响
摘要:为探究种植密度对爆裂玉米产量及品质的影响,以天津农学院特用作物改良工程中心组配的爆裂玉米新组合B1104为试验材料,设置10个密度梯度开展试验。结果表明,在97 500株?hm-2的密度下,产量最高,为4 kg?hm-2,种植密度与爆裂品质并未表现出明显相关关系。

Abstract: In order to explore the influence of planting density on yield and quality of blowout maize, the bination B1104 corn of Tianjin agronomy courtyard with crop improvement engineering center was selected as experimental material
, and ten density gradient was set. The results showed that, under the density of 97 500 plants?hm-2, the yield was the highest, 4 kg?hm-2. There was no apparent correlation between plant density and explosive quality.

爆裂玉米(Zea mays Leverta Sturt)起源于美洲的墨西哥、秘鲁、智利沿安第斯山麓的广大地区,是玉米的八大类型之一,具有独特的膨爆性[1]。它的果穗和籽粒比普通玉米小,子粒几乎全为角质淀粉,质地坚硬。籽粒多为黄色或白色、也有红色、蓝色、棕色,甚至花斑色的。在子粒含水量适当时加热,能爆裂成大于原体积几十倍的呈蘑菇?罨蚝?蝶状的爆米花,而且即使籽粒被砸成碎块时也不会丧失膨爆力。爆裂玉米也由此而得名。第一个用于工厂化生产的爆裂玉
