我国小粒种子作物(指种子千粒重在10克以下的作物)的栽培技术发展很快,但前期作业(播种和省力育苗技术)开发进展较慢,主要是小粒种子作物要做到精量播种是非常困难的。种子包衣丸化(小粒种子大粒化)就是在种子外面包裹含有微量元素、杀菌剂、杀虫剂、生长激素、固氮菌、根瘤菌等的种衣剂,是种子加工现代化的一顶新技术。子包衣丸化后,种子表面物理性状整齐一致,具有良好的机械适应性,适宜精量播种,有利于实现机械化播种,节省种子,减少间苗用工。育
The cultivation technology of China’s small seed crops (crops with a grain weight of less than 10 g) has developed rapidly. However, the early operation (sowing and labor-saving seedling cultivation techniques) has progressed slowly, mainly because the small seed crops must be precision sowed difficult. Seed coating of the pill (granule seed granulation) is wrapped in seeds containing trace elements, fungicides, insecticides, growth hormones, nitrogen-fixing bacteria, rhizobia and other seed coating agent, is a seed processing modernization of a new technology . After the sub-coating and pelleting, the surface physical properties of the seeds are neat and consistent, and have good mechanical adaptability and suitable for precision sowing, which is favorable for mechanized sowing, seed saving and seedling saving.
