Field comparison test was carried out by choosing different types of rice varieties with high yield potential with pot seedling and carpet seedling machine transplanted methods. The results showed that the former seedling quality was higher, survived fast, tillering early, high spike rate, big panicle, more grains and increased output significantly under the same conditions of soil fertility and cultivation management. Under the super high yield cultivation conditions, pot seedling machine transplanted rice had bigger basal internodes, better lodging resistance, early maturing. It provided a new way for safe, stability, efficient and super high yield of a large area of machine transplanted rice cultivation and wheat-rice production.
