小麦深松分层施肥宽苗带免耕播种机的设计与试验

Design and Experiment on Wheat Precision No-tillage Planter with Subsoiling Layered Fertilization and Wide Seedling

根据黄淮海小麦玉米轮作区种植体系的种植要求,研发了一种同时完成深松、分层施肥、播种、覆土及镇压等作业的小麦深松分层施肥宽苗带精量播种机。该播种机采用了深松分层施肥精播技术,在播种时一次性施足包括基肥和底肥在内的控释肥,省去了追肥作业环节,提高了作业效率,显著地降低了生产成本,节能减排,增产增收。试验表明:该机组符合各项指标,满足生产的需要。

According to the Huang-huai-haicropping system of wheat and maize planting,we developed a machine called Wheat precision no-tillage planter with subsoiling layered fertilization and wide seedling which can complete the operation of deep loosening,layered fertilization,sowing,soil covering and compaction at the same time. The seeding machine adopts the precise seeding technology of deep loosening and layered fertilization,At a time when sowing,it provides application of controlled release fertilizer to meet the needs of wheat in different periods,saves the operation fertilizer,improvs working efficiency,reduces production cost,energy saving and emission reduction,increase production.The test results show that the machine can meet the standards and requirements of production.
