虽然玉米和大豆少耕制可减少土壤侵蚀,但也可改变所有的其他生产环节。应该考虑这些生产环节,发展新的植物保护方法,有时还必须探讨新的技术。一种特殊的耕作制对生态系统的物理特性、化学特性和生物学特性具有综合的影响。例如,免耕制与常规耕作相比,春天土壤湿度较高,而土壤温度偏低.使作物残体留在土壤表面的少耕制,其基本概念是与 Although less tillage in maize and soy reduces soil erosion, it can also change all other production processes. These linkages of production should be considered, new methods of plant protection developed and sometimes new technologies explored. A special tillage system has a combined effect on the physical, chemical and biological properties of ecosystems. For example, no-till farming has higher soil moisture in spring and lower soil temperature than conventional tillage. The basic concept of less tillage leaving crop residues on the soil surface is that
