Systematic study on Notoginseng mechanized precision seeding based on integration of agricultural machinery and agronomy

In order to explore the modernization planting patterns of Notoginseng in the means of standardization, scale and engineering, this paper first introduced the systematic thought, divided the Notoginseng mechanized precision seeding system into Notoginseng factory breeding agronomic system, mechanized planting processes and standard system, precision seeding technology system, analyzed co-ordination and mutual adaptation among the three subsystems from the aspect of integration of agricultural machinery and agronomy. Then this paper measured the physical and mechanical characteristics of Notoginseng seeds, including three-axis dimensions, 1 000-grain weight, porosity rate, angle of repose, gliding friction angle. The results showed that, the average three-axis dimensions were 6.20, 5.82, 5.46 mm, the average 1 000-grain weight was 165.86 g, the average porosity rate was 32%, the average angle of repose was 23.2 , the average gliding friction angle on stainless steel plate, metal plate and plastic plate were 21.6, 27.65 , 29.5 respectively
