根据保护性耕作技术模式、技术流程以及作业规模,本着以最少机具完成更多作业和作业面积的原则,这里将推荐3种田间作业机具配置方案。(1)免耕播种机械选择能够满足在免耕、全部秸秆覆盖和高留茬覆盖条件下进行复试播种作业的免耕播种机,一次进地完成深施化肥、苗带秸秆清理、苗带整形、单粒播种、施口肥、挤压覆土、重镇压等工序。 Based on the conservation tillage technology model, technical process and operation scale, and in line with the principle of completing more operations and work areas with the fewest number of machines, three kinds of field work implement configurations are recommended. (1) No-tillage sowing machinery selection No-tillage seeder capable of re-sowing seeding under no-tillage, all-straw mulching and high stubble mulching was completed in one time with deep fertilizer application, seedling with straw straightening and seedling shaping , Single sowing, Shi Kou fat, crush soil, heavy repression and other processes.
