摘要
蔬菜穴盘精量播种是蔬菜工厂化育苗的关键环节,气力式播种是广泛采用的精量播种方法之一。通过试验研究三种类球形蔬菜种子的物理特性,测定其形状尺寸、千粒重、孔隙率、休止角等,为蔬菜气力式穴盘精量播种装置结构和性能参数设计提供依据。
Vegetable seeds precision seeding on potted tray is the one of the main problems in industrial raise of vegetable seedlings.Aerodynamic seeding is one of the widely used precise seeding methods.The experimental study on physical of three kinds of vegetable seeds which are extensively transplanted were carried out.The dimensions,weight of a thousand seeds,porosity,resting angle of vegetable seeds were measured and tested.The results could be as reference for the determination of parameters of structure and performance of aerodynamic vegetable seeds seeding device.
