Abstract:

Rice is one of China’s major food crops. The development of mechanized rice production is of great significance for enhancing China’s comprehensive agricultural production capacity, ensuring food security, increasing farmers’incomes, promoting agricultural supply-side reform and green development. Regulation of rice seedling age is the limiting factor and the key process of rice mechanization production, which has a very significant impact on precision cultivation of rice mechanization production and yield formation. In order to provide an effective way for the entire mechanization of rice development, this paper summarized the classification of rice seedling for mechanized rice production, clarified the existing problem and its developing technical measures of machine-transplanted rice.

Key words: rice, machine-transplanted rice of big seedlings, problem, technical measures
