Abstract:

【Objective】 The objective of this study is to understand the conservation tillage modes and farmers’ adoption, and to reveal the factors influencing farmer adoption. 【Method】 A face-to-face investigations on peasant household were carried out in main demonstration area of conservation tillage of typical ecological region: the Northeast China plain, the North China plain, the Chengdu plain, and the Northwest China oasis. The original data were obtained and the cognition of peasant households on conservation tillage technology was analyzed. 【Result】 Results of research indicate that the conservation tillage adoption rate is higher in the North China plain and the Chengdu plain, the conservation tillage adoption rate is lower in Northeast China plain and the Northwest China oasis. There are some adaptive conservation tillage types in different areas. These tillage types are wide-row and narrow-row rotation planting and leaving high stubble and cutting stubble combined with ridge of tillage mode in the Northeast China plain, rotary tillage seeding technique for sowing wheat under the best row of the corn stalk, no-tillage seeding technique for sowing corn and others under the best row of the whole wheat stalk in the North China plain, no-tillage seeding technique for sowing wheat and others under the best row of the whole rice stalk in Chengdu plain. They have obvious effect on yield increase. The data show that yield increase, government’s demonstration and guide, the example of neighborhood are major factors attracting farmer adopting conservation tillage technology. However, no-matching equipment inhibited the extension of conservation tillage technology. 【Conclusion】 The extension of conservation tillage measures and modes should be determined according to different regional conditions and main limiting factors because of the different ecological factors and productive conditions. The conservation tillage technology should be popularized and developed.
