玉米是我国种植业的主体作物,玉米种子特别是玉米杂交种子的增产幅度较大,对促进“两高一优”农业的发展起着重要作用。因为玉米种子具有:种胚大、营养丰富、含亲水胶体多、细胞组织疏松、种胚的脂肪含量高、种胚的成熟不一致、种胚对低温的耐性差等贮藏特性,所以在贮藏过程中容易吸湿,呼吸强度增大而发热霉烂,容易受仓虫、仓鼠的危害,脂肪易酸败产生有抵制作用的物质,低温下易受冻害等。玉米种子在贮藏中由于技术的不当,轻者会使种子活力下降,重的会丧失种子活力失去种用价值,给生产带来影响,造成经济上的损失。 Corn is the main crop of planting industry in our country. Maize seeds, especially corn hybrid seeds, have a larger yield increase and play an important role in promoting the development of “two high and one excellent” agriculture. Because the corn seeds have: embryo large, nutrient-rich, with many hydrophilic colloids, loose cellular tissue, embryo fat content is high, embryo maturity is inconsistent, poor embryo tolerance to low temperature storage characteristics, so in the storage process Easy to absorb moisture, increased respiratory intensity and fever mildew, susceptible to the hazards of caterpillars, hamsters, fatty acid easily produce resistance to substances, vulnerable to cold damage at low temperatures. Due to improper technology in the storage of corn seeds, the light will reduce the vitality of the seeds, the loss of seed vigor will lose the seed value, affecting the production, resulting in economic losses.
