由北京化工研究院和北京市农业局联合承担的“九五”国家攻关项目一高分子包衣材料用于玉米高产,日前在北京通过技术鉴定。这一新技术是根据玉米种子发芽需要氧气、水分、温度的原理,用高分子聚烯烃材料加工,在玉米种子表层形成种衣膜,在设定的时间内控制外界水分进入种子内,达到控制玉米种子延迟发芽的目的。该项目课题组用所开发的工艺和设备试生产数万斤玉米包衣种子,并在
By the Beijing Chemical Industry Research Institute and Beijing Municipal Bureau of Agriculture jointly assume “95 ” a national research project of a polymer coating material for high-yielding corn, recently passed the technical appraisal in Beijing. This new technology is based on the principle of germination of corn seeds need oxygen, water, temperature, processing with high molecular weight polyolefin materials, the formation of seed coating on the surface of the corn seed, within a set period of time to control the outside water into the seeds, to control Corn seeds delay germination. The project team with the development of technology and equipment to test the production of tens of thousands of jins of corn seed coating, and
