Harvesting, drying and storage of paddy are three important links, these three links are not independent matters, but interrelated each other, the former affects the latter． In actual production, many producers do not harvest paddy at the best time, a few of them were harvested early by cutting and sunning, and most of them were harvested after early stage of ripening for better threshing, in the north still has the harvest after frost． Paddy in the south will be piled up on site before drying, which would become mildew and rot after a long time． When paddy is stored at normal temperature and ventilated, it is easy to cause fever, roof topping, diseases and insect pests in the barn under high temperature and humidity． These traditional methods can cause paddy losses and nutrient loss to varying degrees． In view of existing problems in three links of paddy harvesting, drying and storage in China and specific measures for grain saving and loss reduction, new scientific and reasonable suggestions and methods were put forward for research, discussion and gradual implementation, so as to promote technical progress in these three links of production and minimize the loss of paddy．
