中国是世界上盛产稻米的国家,水田面积占世界水田面积的四分之一,而水田耕整作业季节性强、耗工多、劳动强度大,迫切需要机械化。我国创制的机耕船,采用“浮”式工作原理,突破了传统拖拉机的形态,表现了较好的适应性与经济性,深受我国平原湖区农民的欢迎。机耕船能适应我国南方很多地区的自然环境,特别是机耕船在平原湖区作业时,生产率、耗油量、作业成本等技术经济指标一般优于传统的拖拉机,表现了较好的优势。如果在设计、制造上加强机耕船的综合利用,进一步提高它的可靠性、耐用性,机耕船的适应性经济性将进一步提高。 China is a country rich in rice in the world. Paddy fields account for one-fourth of the paddy field in the world. However, paddy field tillage operations are seasonal, labor-intensive and labor-intensive. There is an urgent need for mechanization. The plow-cultivating vessel created in our country has adopted the working principle of “floating” type, which has broken through the traditional tractor form, showing good adaptability and economy, and is deeply welcomed by peasants in the plain Lake region of our country. Machine-driven farming can adapt to the natural environment in many parts of South China. Especially when the plow-cultivating craft operates in the plains and lakes, the technical and economic indexes such as productivity, fuel consumption and operating cost are generally superior to the traditional tractors and show better advantages. If the design and manufacture of enhanced comprehensive utilization of plowed vessels to further enhance its reliability, durability, adaptive economy of plowed vessels will be further improved.
