机械化免耕播种是针对传统耕作弊端而发展的一种新技术,通过取消铧式犁耕翻,在地表保留大量或部分残茬覆盖下,以对土壤结构最小的扰动,进行作物播种,以达到保护土壤、节水抗旱、增加农民收入等积极的目的。京郊地区目前已基本实现夏玉米免耕播种,由于播种地面条件与传统耕作的不同而需要专门的播种机械,这也是该项技术实施的关键。目前,国产免耕机具大多处于开发、试验阶段,适应性和可靠性差。进口机型虽然性能好,但价格贵。为探讨和开发适合中国国情的机型,北京市大兴区农机研究所对迪尔免耕条播机进行了试验作业,取得了阶段性成果。 Mechanized no-till sowing is a new technique developed against the drawbacks of traditional farming. Crops are sown to achieve minimum disturbance to soil structure by eliminating plow trowels and covering the surface with large or partial residues Protect the soil, water and drought, increase farmers’ income and other positive purposes. At present, suburbs of Beijing have basically realized no-till summer sowing of summer maize, and special sowing machinery is needed due to different ground sowing conditions and traditional farming practices. This is also the key to the implementation of this technology. At present, most of the domestic tillage machines are in the development and experimental stage, with poor adaptability and reliability. Although the performance of imported models, but expensive. In order to explore and develop models suitable for China’s national conditions, Daxing District, Beijing Institute of Agricultural Machinery on Deere tillage drill was tested and achieved initial results.
