The adoption of green technology is a key link to realize the green transformation of agriculture and an important support to promote the sustainable development of agriculture. This paper used 429 sample data of grain business households in Changzhou, Yangzhou, Yancheng and Huai’ an, Jiangsu Province, and on the basis of theoretical analysis, used the binary Probit model to empirically analyze the impact of land fragmentation and organizational embeddedness on farmers’ green technology adoption. The results showed that, land fragmentation had a significant inhibitory effect on the adoption of green technology by farmers, and organizational embeddedness had a significant role in promoting the adoption of green technology by farmers. Further adjustment effect analysis found that organizational embeddedness significantly alleviated the constraint effect of land fragmentation on farmers’ green technology adoption. Therefore, from the policy perspective of promoting the adoption of green technology by farmers, it was necessary to promote centralized and contiguous land management, attach importance to the key role of organization embeddedness in promoting the green technology behavior of farmers, and improve the possibility of farmers adopting green technology.
