Study on Minimum Tillage with Water Saving Technology and Implement for Paddy Field
(0) In the paper, a brand-new method of tillage and soil preparation for paddy field is discussed, the method using a special rototiller to rotary hoeing field in strip, instead of the traditional moldboard plow or rotary tillage. The characteristics of this tillage method are as follows: first, reduce the power consumption and the operation cost significantly comparing to tradition tillage and soil preparation for paddy field. For the adoption of new strip minimum tillage, soil humifying and rice seedling transplanting, the 4 operations of harrowing, smashing, leveling and dragging paddy residue were canceled, and the power consumption was reduced, the cost for soil preparation was saved 50 to 60％.Second, compared to traditional soil preparation, the wastage of water for dunking field was saved 30 to 40％, thus, it is a new and high effective technology in saving water. Third, it can curtail the period of tilage and soil preparation for paddy field from the primary 10 to 15 days to 1 to 2 days. Forth, it realized the conservation tillage by reduced tillage and putting rootstalk and part of straws back into field. Fifths, it increases outputs and income 18％. This technology is an innovation and has a great function on the development of paddy production.
