摘要
松耕作业能打破犁底层、恢复土壤结构,形成适宜农作物生长的土体构造,是提高地表积温和作物产量的有效措施之一。为此,探讨了在秸秆覆盖条件下各种松耕作业机具的工艺特点及机具在保护性耕作播前作业中的适应性。
Loosening tillage can break the bottom of plough and reform soil fabric. It forms new soil fabric to suit for creature growth. It is a way to increase soil temperature and creature yield. The paper mainly researches on working performances of kinds of loosening implements under mulching system, and loosening implement抯 adaptability to work before conservation sowing.
