Study on the Implementation ofthe Comprehensive Technologies of Paddy Field Mechanization for Increasing Production

This paper briefly presents the main contents, procedures and methods of implementing the project "the comprehensive technologies of paddy field mechanization for increasing pro-sduction", and the results after the implementation of the project, which include an increase of 57.8 kg paddy per mu,an economization of 15 man-days per mu and a decrease of 10.6 Yuan per mu in production cost. It is obtained, based on the economic benefit analysis, that the ratio of investment in science and technology to benefit is 1:15.35, with an economic critical point 1:16.35. The procedures and methods are of value to popularize in the two-crop paddy areas. Some basic method about the mechanization of paddy field operations and the implementation of bumper harvest plan are also discussed.
