| Abstract: | For the application of "hidden ridge close planting" in high yield soybean cultivation techniques, a multifunctional precision seed spacing drill was developed with the functions of no ridge flat planting, double-row drilling, multilayer subsoil fertilizer application. And a national patent for utility model for the drill has been obtained. After performance test and field trial, with the design of the sliding blade fertilizer coulter and twin disk seed coulter, and by using a vertical indent hole wheel feed run, outside grooved wheel fertilizer feed in the drill, it has been proved that the technical performance of the drill met the requirements of "hidden ridge close planting" in high yield soybean cultivation techniques, the soybean yield could be increased by more than 20%. The drill is proved to be suitable for extending application in soybean production areas. |
| Keywords: | soybean "hidden ridge close planting" drill fertilization |
