有关种子包衣的研究,以前主要是集中在改善种子的不规则外形、防治病虫害、改善苗期及作物的营养和提高种子对自然环境的抵抗力等方面。根据我国人多地少的农业特点,中石化集团公司北京化工研究院以早播晚出为指导思想,开发出高分子玉米包衣材料,使传统套播作业提前,即可克服农业机械无法在麦收前进入田间作业的困难,又能达到套种高产的目的,并从根本上防止了燃烧麦秸,有利于环境保护。该项目已申请了中国发明专利。
Studies on seed coating have mainly focused on improving the irregular appearance of seeds, controlling pests and diseases, improving seedling and crop nutrition, and improving seed resistance to the natural environment. According to the agricultural characteristics of our country with a small population, the Beijing Chemical Industry Research Institute of SINOPEC, with the principle of early sowing late, as the guiding ideology, developed polymer corn coating material to make the traditional crop planting work ahead of time, Before entering the field operation difficulties, but also to achieve the purpose of high-yielding intercropping, and fundamentally prevent the burning of wheat straw, is conducive to environmental protection. The project has applied for a Chinese invention patent.
