由北京农业大学与河北省曲周县农机研究所共同研制的2BXT-3型铁茬播种机于今年初通过省厅级科研新产品鉴定。该机是在2BXA-12型播种机基础上改进的。改进后的2BXT-3型铁茬播种机除具有原机一切性能外,既可在平整地后播种谷类作物,还能在小麦收割后铁茬地上直接播种各种夏茬作物,如玉米、豆类、谷子、棉花等。可一次完成开沟、排种、覆土、镇压等全过程。此机的问世为实现全面覆盖、免耕打下了基础。 2BXT-3 type stubble sowing machine jointly developed by Beijing Agricultural University and Quzhou County Agricultural Machinery Research Institute of Hebei Province passed the appraisal of provincial and ministerial level scientific research new products earlier this year. This machine is based on 2BXA-12 planter improved. Improved 2BXT-3 stubble planter in addition to the original machine with all the performance, both in the smooth after the sowing of cereal crops, but also in the wheat after harvest stubble direct seeding of various summer crops, such as corn, beans Category, millet, cotton and so on. Can be completed once ditching, seeding, soil cover, the entire process of repression. The advent of this machine to achieve full coverage, laid the foundation for no-till.
