保护性耕作是农业部重点推广的技术之一。但是,由于这项技术是对传统耕作技术的变革,农民接受困难,需要强化培训。常规的培训教材大部分以文字为主,农民不愿看,或者看不懂,培训效果差,对保护性耕作的培训方式提出了新的要求。农业部保护性耕作研究中心李洪文教授等人在多年从事保护性耕作技术研究,并参与编写相关培训材料基础 Conservation tillage is one of the key technologies promoted by the Ministry of Agriculture. However, since this technology is a revolution in traditional farming techniques, farmers have to accept difficulties and need intensive training. Most of the conventional training materials are text-based. Peasants are unwilling to read, or do not understand, the training effect is poor, putting forward new requirements on the training methods of conservation tillage. Professor Li Hongwen from the Conservation Tillage Research Center of the Ministry of Agriculture has been engaged in the research of conservation tillage for many years and has been involved in the preparation of relevant training materials
