Abstract: Food legumes is an important edible crop in China, there are more than 20 kinds that have been cultivated, and the main varieties are mung bean, adzuki bean, broad bean, pea and kidney bean. It is an important means to promote the development of food legumes crops mechanization in China. Due to the large variety of food legumes, wide geographical distribution and various planting modes, the lack of efficient harvesting equipment is an urgent technical problem to be solved in the current production process. Through the analysis of the development status of food legumes industry at home and abroad, combined with the current research results of combined harvest technology and the particularity of mechanized harvest of food legumes, and based on the analysis of the applicability of the existing combined harvest technology, this paper puts forward the mechanized loss reduction harvest technology strategy suitable for the production of food legumes in China. The analysis shows that to reduce the harvest loss of food legumes, we need to comprehensively consider several aspects, such as the selection of suitable mechanized varieties and supporting planting agronomy, the application of multidimensional loss reduction technology of combined harvest machines and tools, and strengthening personnel skill training. The above methods can effectively reduce the loss before harvest and cutting, header loss, threshing loss and cleaning loss. At the same time through the integrated application of low loss harvesting header, efficient threshing and cleaning, and low loss material transportation technology, the harvest loss rate of food legumes combine harvester can be greatly reduced, and the loss reduction effect is remarkable.
