Economic analysis on the adaptability of the major grain post-production patterns in South China.

An analysis model was established in order to evaluate the adaptability of grain post-production patterns from harvesting to drying for different economic circumstances using three components, i.e. labour cost saving effects, benefits from increased production or reduced losses, and income from saved labour. System analysis of four major patterns of grain post-production existing in South China was undertaken using the model. The pattern: 'manual harvesting - manual threshing - manual cleaning - sun drying' was suitable for areas where technical and economic conditions were relatively low and labour was abundant with an average value of less than 2.62 yuan/d. Patterns comprising a higher degree of mechanization were more suitable in areas where the technical and economic conditions were more favourable and manpower was more scarce and more expensive.
