Abstract：Mechanical transplanting is the key link of the whole mechanized seed production technology of hybrid rice,and the seedling quality determines the success or failure of hybrid rice seed production.After many years of experimental research on precision printing sowing and Mechanical transplanting of parents,the seedling raised by printing sowing can greatly prolong the seedling age and improve the seedling quality.The paper introduces the technological process and matters needing attention of printing-sowing technology in large-scale production in detail,and puts forward the matching seed production technology,which provides a strong guarantee for the stability and replicability of high-quality mechanical transplanting seedlings,and lays a foundation for the integration and application of the key techniques of the whole mechanized seed production of hybrid rice.
