Abstract: 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.

摘要： 选用具有超高产潜力的不同类型水稻品种为材料，进行钵苗机插与毯苗机插两种育插秧方式比较试验。结果表明，在同等地力及栽培管理水平条件下，钵苗机插秧苗素质高，大田活棵快，低位分蘖发生早，成穗率高，穗大粒多、粒重，增产效应显著。同时，在超高产栽培条件下，钵苗机插基部节间增粗，抗倒性增强，成熟期提前。钵苗机插为大面积机插水稻稳定超高产栽培及稻麦两熟周年安全高效生产开辟了一条新的途径。
